Omicron and Vaccines: What You Should Know

Omicron is unlikely to have completely outsmarted the vaccines, experts say, even with its unusual array of mutations. 

There are a lot of unknowns, but they expect that the shots will still do what they do best: Keep people out of the hospital and out of the grave.

Omicron raised alarms when it was first identified during a sharp spike in cases in South Africa. The World Health Organization added it to its list of variants of concern last week.

The virus contains dozens of mutations, including several that are thought to make it more infectious and others that appear to help it evade the immune system.

“But I think it’s still very possible that vaccines will hold up against severe disease, even with those mutations,” said Dr. Carlos del Rio, a professor of medicine at Emory University and president-elect of the Infectious Diseases Society of America.

That’s what has happened with every variant so far. With delta, he noted, “breakthrough” infections among vaccinated people have increased, but those cases are mostly mild.

Omicron seems to be better able than other variants to infect people who have already had COVID-19, according to early data from South Africa. But people with reinfections generally have not been seriously ill.

Experts are recommending boosters for people who can get them. U.S. officials have authorized them for everyone age 18 and older. 

Open questions 

Researchers will have more questions than answers about omicron for the next few weeks while they study the variant. They don’t yet know for sure how the virus stacks up against other variants in terms of how easily it infects or how sick it makes its victims.

Hospitalizations have increased in South Africa during the omicron surge, but it’s not clear if that’s because the virus causes more severe infections or because more people are getting infected. Most of the country is not vaccinated. 

Scientists need to figure out whether the rise in infections is “vaccine failure or failure to vaccinate,” said Dr. Walter Orenstein, associate director of the Emory University Vaccine Center.

“If it’s vaccine failure, is it a problem of time since the last dose and waning immunity?” Orenstein said. 

Though it does not yet seem to be necessary, some companies are working on modifying their vaccines to better protect against the new variant.

Moderna and the Pfizer-BioNTech partners say they can have a new vaccine ready in about three months. Johnson & Johnson says it is working on a new version but did not give a timeline. Oxford University told Reuters news agency that the vaccine it produces with AstraZeneca is still highly effective but that it can quickly update it if necessary. 

Many companies have started developing modified vaccines against previous variants, but none has gone to regulators for approval.

The U.S. Food and Drug Administration says it will not require drugmakers seeking approval for their updated vaccines to go through a process as lengthy as the one for the original versions. Much like with the annual flu vaccine, a few tests for safety and immune response will do.

NASA Astronauts Conduct Previously Postponed Spacewalk

Two astronauts with the U.S. space agency, NASA, left the International Space Station (ISS) Thursday to conduct a spacewalk to replace a broken antenna system, two days after the walk was postponed over concerns about space debris.

NASA astronauts Thomas Marshburn and Kayla Barron stepped out of the ISS airlock early Thursday to replace the faulty antenna, used to communicate voice and data to ground control. The operation was expected to last six-and-a-half hours.

The spacewalk had originally been scheduled for Tuesday but was postponed late Monday after NASA said it had received a notification of space debris that it needed to assess. The space agency said once it determined the debris did not pose a risk, the operation was rescheduled for Thursday.

It was not immediately clear whether the debris field that prompted the spacewalk to be postponed was related to a Russian anti-satellite missile test two weeks ago. That event created a debris field that forced ISS crew members to seek shelter in their escape capsules as a precaution.

US Seeks Norms for Outer Space After ‘Irresponsible’ Russia Test 

U.S. Vice President Kamala Harris on Wednesday criticized an “irresponsible” Russian test that endangered the International Space Station with debris, and the Biden administration laid out a new strategy for responsible use of space. 

Harris convened the inaugural meeting of the National Space Council and asked members of the government body to promote responsible civil, commercial and national security-related behavior in space, where there are growing commercial interests and concerns about Chinese and Russian competition. 

“Without clear norms for the responsible use of space we stand the real risk of threats to our national and global security,” Harris said. 

She said Russia’s “irresponsible act” of testing anti-satellite technology last month created debris that endangered the International Space Station (ISS). 

U.S. officials have fretted over rising security activity by Washington’s major rivals in space. China’s test of hypersonic weapons this year raised the prospect of an arms race over Earth-orbiting systems that could dodge current missile defenses. 

Meanwhile, a growing number of companies, including SpaceX, Blue Origin and Virgin Galactic, are seeking to usher in a new era of private commercial space flights following years of private firms working alongside the U.S. government’s National Aeronautics and Space Administration (NASA) in rocket launches. 

President Joe Biden also signed an executive order on Wednesday adding the heads of the Education, Labor, Agriculture and Interior Departments as well as his national climate adviser to the National Space Council. 

The administration also wants the group’s work to increase space climate data and enhance scientific-related efforts that could aid job creation and U.S. competitiveness, it said in a statement. 

The National Space Council is separate from the U.S. Space Force military branch created under former President Donald Trump.

Biden Marks 33rd World AIDS Day With New Commitments

Marking the 33rd annual World AIDS Day on Wednesday, the Biden administration announced it would ramp up its domestic and international efforts to fight the HIV virus, which has killed 36 million people worldwide in four decades.

President Joe Biden also released Wednesday the domestic-focused National HIV-AIDS Strategy, which aims for a 90% reduction in new HIV cases in the U.S. over the next nine years. Currently, about 1.2 million Americans are thought to be living with the virus. The epidemic peaked in the U.S. in the 1980s.

The administration has said that racism that leads to unequal medical care is itself “a public health threat” that needs to be acknowledged in the battle against the virus. 

The president offered two new measures aimed at ending the epidemic in the United States by 2030 and boosting U.S. efforts to end the spread of HIV, the virus that can progress to AIDS, around the world.

“Today, we once more raise a two-story-tall red ribbon from the North Portico of the White House to remember how far we have come,” Biden told an audience of American activists, politicians and medical experts, including AIDS research pioneer Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. “And the work we have left to finish, so we never forget the prices paid all along the way.” 

Internationally, where the bulk of new infections occur, the U.S. seeks to increase donor funding. On Wednesday, Biden said the U.S. would host the Global Fund to Fight AIDS replenishment conference next year. The U.S. is the fund’s largest donor, contributing about $17 billion to it last year. That’s in addition to a commitment Biden made earlier this year in which he sent $250 million of American Rescue Plan funding to the President’s Emergency Plan for AIDS Relief (PEPFAR), a program established in 2003 by President George W. Bush to combat the disease internationally.

Slow, unequal response 

Still, it’s not clear whether even that infusion of funds will right the ship. The United Nations’ AIDS organization said Wednesday that the global goal to end the epidemic by 2030 has been derailed — and not just by the coronavirus pandemic that upended global health policy and practices.

“Even before the COVID-19 pandemic hit, many of the populations most at risk were not being reached with HIV testing, prevention and care services,” said Tedros Adhanom Ghebreyesus, director-general of the World Health Organization. “The pandemic has made things worse, with the disruption of essential health services and the increased vulnerability of people with HIV to COVID-19. Like COVID-19, we have all the tools to end the AIDS epidemic, if we use them well. This World AIDS Day, we renew our call on all countries to use every tool in the toolbox to narrow inequalities, prevent HIV infections, save lives and end the AIDS epidemic.” 

Tedros has warned that discrimination and inequality are at the root of the epidemic, and that inattention to these problems would lead to 7.7 million AIDS-related deaths in the next 10 years. 

Other critics have knocked Biden for not moving fast enough on his promises to fight HIV. In August, the world’s premier medical journal, The Lancet, published a critique of Biden’s pace in nominating a new leader for PEPFAR. Biden announced his pick for the job, Cameroon-born John Nkengasong, a U.S. citizen who heads the Africa Centers for Disease Control and Prevention, in late September. The Senate received the nomination in mid-October and referred it to the Committee on Foreign Relations, where it remains.

“During his candidacy, U.S. President Joe Biden committed to prioritizing the global AIDS response,” the authors — two American and two African activists — wrote in the medical publication. “This promise has been contradicted by a 6-month delay in nominating an ambassador-at-large to lead PEPFAR, which has functioned without a presidentially appointed health diplomat since Ambassador Deborah L. Birx was detailed to the White House Coronavirus Task Force in February 2020.”

On Wednesday, as he recognized Nkengasong among the crowd gathered at the White House, Biden was hopeful.

“We can do this,” he said. “We can eliminate HIV transmission. We can get the epidemic under control in the United States and in countries around the world. We have a scientific understanding. We have treatments. We have the tools we need. We’re going to engage with people with lived experience with HIV and ensure that our efforts are appropriate and effective and centered around the needs of the HIV community.”

Biden HIV/AIDS Strategy Calls Racism ‘Public Health Threat’

The Biden administration in its new HIV/AIDS strategy calls racism “a public health threat” that must be fully recognized as the world looks to end the epidemic.

The strategy released Wednesday on the annual commemoration of World AIDS Day is meant to serve as a framework for how the administration intends to shape its policies, research, programs and planning over the next three years.

The new strategy asserts that over generations “structural inequities have resulted in racial and ethnic health disparities that are severe, far-reaching, and unacceptable.”

New HIV infections in the U.S. fell about 8% from 2015 to 2019, but Black and Latino communities — particularly gay and bisexual men within those groups — continue to be disproportionately affected, according to Centers for Disease Control and Prevention data.

African Americans make up about 13% of the U.S. population but accounted for more than 40% of new infections. The Latino population accounted for nearly 25% of new infections but makes up about 18.5% of the U.S. population.

Historically, gay and bisexual men have been the most disproportionately affected group. They account for about 66% of new HIV infections, even though they account for only 2% of the population, according to the CDC. In 2019, 26% of new HIV infections were among Black gay and bisexual men, 23% among Latino gay and bisexual men, and 45% among gay and bisexual men under the age of 35.

To reduce the disparities, the strategy includes calls for focusing on the needs of disproportionately affected populations, supporting racial justice, combating HIV-related stigma and discrimination and providing leadership and employment opportunities for people with or at risk for HIV.

Besides addressing racism’s impact on Americans battling the virus or at risk of contracting it, the new strategy also puts greater emphasis on harm reduction and syringe service programs, encourages reform of state laws that criminalize behavior of people with HIV for potentially exposing others and adds focus on the needs of the growing population of people with HIV who are aging.

More than 36 million people worldwide, including 700,000 in the U.S., have died from AIDS-related illnesses since the start of the epidemic more than 40 years ago. Nearly 38 million people are living with HIV, including 1.2 million in the U.S.

President Joe Biden’s administration recently announced it will host the Global Fund to Fight AIDS replenishment conference next year. The United States has contributed about $17 billion to the fund, about a third of all donor contributions.

A giant red ribbon, a symbol of support for people living with HIV, was also displayed on the North Portico of the White House to mark World AIDS day. The two-story ribbon display has become an annual tradition at the White House since 2007.

“Honored to continue this tradition on #WorldAidsDay, remembering the lives lost to HIV/AIDS and supporting those living with the virus across the world,” first lady Jill Biden said in a Twitter posting that included a photo of her posing in front of the ribbon display.

EU Leaders Consider Mandatory Vaccinations to Fight Omicron Variant

European Union leaders said Wednesday they are considering a number of public health options, including vaccine mandates, to address the growing threat posed by the omicron variant of the virus that causes COVID-19. 

Speaking to reporters in Brussels, European Commission President Ursula von der Leyen said little is currently known about the variant, but enough is known to be concerned. She said they expect scientists to have a handle on the nature of the variant in about two to three weeks, but in the meantime are hoping for the best and preparing for the worst. 

Von der Leyen said the best use of that time is to get more people vaccinated, and those who are inoculated should get booster shots. She said more than one-third of the European population — 150 million people — are not vaccinated.

The European Commission president said that while not everyone can be vaccinated, the majority of people can.

“This needs discussion. This needs a common approach, but it is a discussion that I think has to be had,” she said. 

Von der Leyen said Pfizer-BioNTech has indicated it can accelerate the production and distribution of its children’s vaccine, which will be available to European children beginning December 13.

She also said Pfizer and Moderna are set to deliver 360 million more doses of their vaccines by the end of March 2022, and that boosters are available to those who received their initial shots. 

The commission also urged EU members to commit to a day-by-day review of travel restrictions and a readiness to impose all necessary controls, including decisive action, if clusters of the omicron variant are found.

WHO Works Toward International Pact on Pandemic Prevention 

The World Health Organization (WHO) Wednesday began a lengthy process to develop an international agreement on the prevention and control of future pandemics.

The WHO’s World Health Assembly – the organization’s decision-making body – approved the effort at the end of a rare, three-day special session at the organization’s headquarters in Geneva. The plan, entitled “The World Together,” was created as the world is facing the new omicron variant of coronavirus. 

WHO Director-General Tedros Adhanom Ghebreyesus praised the decision, saying the pandemic has exposed shortcomings in the application and implementation of international health regulations established by the WHO in 2005.

The agreement would establish international standards on issues ranging from data sharing and genome sequencing of emerging viruses to equitable distribution of vaccine and drugs. 

Wednesday’s decision begins the process of drafting and negotiating the agreement, which is not expected to be completed until May 2024.

The European Union (EU) had pushed for the agreement on an international legally binding treaty, along with about 70 countries, but Brazil, India and the United States were among those reluctant to commit to a treaty, diplomats said. 

More than 262.22 million people have been reported infected with SARS-CoV-2, the virus responsible for COVID-19, and 5.46 million people have died of it since it emerged in China in December 2019.

Nigeria Detects First Case of Omicron Variant from October

Nigeria has detected its first case of the omicron coronavirus variant in a sample it collected in October, weeks before South Africa alerted the world about the variant last week, the country’s national public health institute said Wednesday.

It is the first West African country that has recorded the omicron variant since scientists in southern Africa detected and reported it and adds to a list of nearly 20 countries where the variant has been recorded, triggering travel bans across the world. 

Genomic sequencing of positive cases of COVID-19 in Nigeria identified two cases of the omicron variant among travelers from South Africa, the Nigeria Center for Disease Control said in a statement issued by its director-general.

The two unidentified travelers arrived in the West African country last week, but the variant has also been confirmed in cases in Nigeria prior to their arrival.

“Retrospective sequencing of the previously confirmed cases among travelers to Nigeria also identified the omicron variant among the sample collected in October 2021,” Nigeria CDC director-general Dr. Ifedayo Adetifa said.

Much remains unknown about the new variant, including whether it is more contagious, as some health authorities suspect, whether it makes people more seriously ill, and if it can thwart the vaccine.

The Nigeria CDC urged the country’s states and the general public to be on alert and called for improved testing amid concerns that Nigeria’s low testing capacity might become its biggest challenge in the face of the new variant.

Testing for the virus is low in many states and even in the nation’s capital, Abuja. For instance, in parts of Kuje, a suburb of Abuja, Musa Ahmed, a public health official, told The Associated Press that no one has been tested for the virus for weeks.

The detection of the omicron variant in Africa’s most populous nation, with 206 million people, coincides with Nigeria’s new requirement that all federal government employees must be inoculated or present a negative COVID-19 test result done in the last 72 hours. 

With the vaccine mandate taking effect on Wednesday, there were chaotic scenes at several offices in the nation’s capital as civil servants without a vaccination card or a negative PCR test were turned away by security agents.

Many of the workers and security agents were not wearing face masks.

“Governments should invest in promoting narratives around vaccine safety, efficacy, and the broader public health security implications of poor vaccines uptake,” Adewunmi Emoruwa, lead strategist at Gatefield, an Abuja-based consultancy. “If public servants are convinced about these issues, they are naturally more effective advocates to their constituents.”

Across Nigeria, the news of the omicron variant — which the World Health Organization has warned poses “very high” risk — has triggered concerns and renewed fears over the COVID-19 pandemic.

At the airport in Lagos, Nigeria’s largest city and economic hub, authorities insisted that travelers must wear their face masks at the counters, though not much attention is paid to many others flouting health protocols around the airport premises and in the city. 

Nigeria — with 214,218 confirmed infections including nearly 3,000 deaths — has updated its travel advisory, ordering incoming international travelers to have a PCR test 48 hours before embarking on their trip to the country and two more tests, two days and seven days after arrival. Incoming international arrivals must also isolate for seven days.

Amid global concern over the omicron variant, the Nigeria CDC director-general told reporters that the country remains at alert in the face of the emerging crisis.

“We are working very hard to enhance ongoing surveillance, especially for inbound travelers, and also trying to ramp up testing (including) at the land borders,” he said.

A slew of nations moved to ban travels from many countries especially southern African nations in the aftermath of the emergence of the omicron variant. But the move has been widely condemned by many including South Africa President Cyril Ramaphosa, who is currently in Nigeria on a two-day visit.

Space Junk Forces Spacewalk Delay, Too Risky for Astronauts 

NASA called off a spacewalk Tuesday because of menacing space junk that could puncture an astronaut’s suit or damage the International Space Station. 

Two U.S. astronauts were set to replace a bad antenna outside of the space station. But late Monday night, Mission Control learned that a piece of orbiting debris might come dangerously close. There wasn’t enough time to assess the threat so station managers delayed the spacewalk until Thursday. 

It’s the first time a spacewalk has been canceled because of threat from space junk. 

The space station and its crew of seven have been at increased risk from space junk since Russia destroyed a satellite in a missile test two weeks ago. 

It wasn’t immediately clear whether the object of concern was part of the Russian satellite wreckage. During a news conference Monday, NASA officials said the November 15 missile test resulted in at least 1,700 satellite pieces big enough to track, and thousands more too small to be observed from the ground but still able to pierce a spacewalker’s suit. 

NASA officials said astronauts Tom Marshburn and Kayla Barron faced a 7% greater risk of a spacewalk puncture because of the Russian-generated debris. But they said it was still within acceptable limits based on previous experience. 

Marshburn and Barron arrived at the space station earlier this month.

FDA Panel Backs First-of-a-Kind COVID-19 Pill From Merck

A panel of U.S. health advisers on Tuesday narrowly backed a closely watched COVID-19 pill from Merck, setting the stage for a likely authorization of the first drug that Americans could take at home to treat the coronavirus. 

A Food and Drug Administration panel voted 13-10 that the drug’s benefits outweigh its risks, including potential birth defects if used during pregnancy. 

The recommendation came after hours of debate about the drug’s modest benefits and potential safety issues. Experts backing the treatment stressed that it should not be used by anyone who is pregnant and called on the FDA to recommend extra precautions before the drug is prescribed, including pregnancy tests for women of child-bearing age. 

The vote specifically backed the drug for adults with mild-to-moderate COVID-19 who face the greatest risks, including older people and those with conditions like obesity and asthma. Most experts also said the drug shouldn’t be used in vaccinated patients, who weren’t part of the study and haven’t been shown to benefit. 

The FDA isn’t bound by the panel’s recommendation and is expected to make its own decision before year’s end. The pill is already authorized in the United Kingdom. 

The drug, molnupiravir, could provide a much-needed weapon against the virus as colder weather pushes case counts higher and U.S. officials brace for the arrival of the new omicron variant.

Merck hasn’t specifically tested its drug against the new variant but said it should have some potency based on its effectiveness against other strains of the coronavirus. 

But that uncertainty frustrated many panelists as they grappled with whether to back the treatment for millions of Americans. 

“With no data saying it works with new variants, I really think we need to be careful about saying that this is the way to go,” said Dr. David Hardy of Charles Drew University School of Medicine and Science, who ultimately voted to back the drug. 

Effectiveness, dangers

The panel’s narrow-but-positive recommendation came despite new data from Merck that paint a less compelling picture of the drug’s effectiveness than just a few weeks earlier. 

Last week, Merck said final study results showed molnupiravir reduced hospitalization and death by 30% among adults infected with the coronavirus, when compared with adults taking a placebo. That effect was significantly less than the 50% reduction it first announced based on incomplete results. 

That smaller-than-expected benefit amplified experts’ concerns about the drug’s toxicity for fetuses. 

FDA scientists told the panelists earlier Tuesday that company studies in rats showed the drug caused toxicity and birth defects when given at very high doses. Taken together, FDA staffers concluded the data “suggest that molnupiravir may cause fetal harm when administered to pregnant individuals.” 

FDA is weighing a blanket restriction against any use in pregnant women or allowing it in rare cases. Some panelists said the option should be left open for pregnant mothers who have high-risk COVID-19 and may have few other treatment options. 

Dr. Janet Cragan, who backed the drug, said that even with tight restrictions, some pregnant women would inevitably take the drug.

“I don’t think you can ethically tell a woman with COVID-19 that she can’t have the drug if she’s decided that’s what she needs,” a panel member and staffer with the Centers for Disease Control and Prevention. “I think the final decision has to come down to the individual woman and her provider.”

Merck’s drug uses a novel approach to fight COVID-19: It inserts tiny errors into the coronavirus’ genetic code to stop it from reproducing. That genetic effect has raised concerns that the drug could spur more virulent strains of the virus. But FDA regulators said Tuesday that risk is theoretical and seems unlikely. 

Pfizer drug

While Merck and its partner Ridgeback Biotherapeutics were the first to submit their COVID-19 pill to the FDA, rival drugmaker Pfizer is close behind with its own pill under review. 

Pfizer’s drug is part of a decades-old family of antiviral pills known as protease inhibitors, a standard treatment for HIV and hepatitis C. They work differently than Merck’s pill and haven’t been linked to the kind of mutation concerns raised with Merck’s drug. 

Pfizer said this week that its drug shouldn’t be affected by the omicron variant’s mutations. 

The U.S. government has agreed to purchase 10 million treatment courses of Pfizer’s drug, if it’s authorized. That’s more than three times the government’s purchase agreement with Merck for 3.1 million courses of molnupiravir. 

Both drugs require patients to take multiple pills, twice a day for five days.

1st French Omicron Case on Indian Ocean Island of Reunion

Japan and France confirmed their first cases of the new variant of the coronavirus on Tuesday as countries around the world scrambled to close their doors or find ways to limit its spread while scientists study how damaging it might be.

The World Health Organization has warned that the global risk from the omicron variant is “very high” based on early evidence, saying it could lead to surges with “severe consequences.”

French authorities on Tuesday confirmed the first case of the omicron variant in the French island territory of Reunion in the Indian Ocean. Patrick Mavingui, a microbiologist at the island’s research clinic for infectious diseases, said the person who has tested positive for the new variant is a 53-year-old man who had traveled to Mozambique and stopped in South Africa before returning to Reunion.

The man was placed in quarantine. He has “muscle pain and fatigue,” Mavingui said, according to public television Reunion 1ere.

Japan on Tuesday confirmed its first case in a visitor who recently arrived from Namibia, a day after banning all foreign visitors as an emergency precaution against the variant. A government spokesperson said the patient, a man in his 30s, tested positive upon arrival at Narita airport on Sunday and was isolated and is being treated at a hospital.

Cambodia barred entry to travelers from 10 African countries, citing the threat from the omicron variant. The move came just two weeks after Cambodia reopened its borders to fully vaccinated travelers on Nov. 15.

The new version was first identified days ago by researchers in South Africa.

WHO said there are “considerable uncertainties” about the omicron variant. But it said preliminary evidence raises the possibility that the variant has mutations that could help it both evade an immune-system response and boost its ability to spread from one person to another.

The WHO stressed that while scientists are hunting evidence to better understand this variant, countries should accelerate vaccinations as quickly as possible.

Despite the global worry, doctors in South Africa are reporting patients are suffering mostly mild symptoms so far. But they warn that it is early. Also, most of the new cases are in people in their 20s and 30s, who generally do not get as sick from COVID-19 as older patients.

Biden Urges Calm, Vaccination, in Face of Omicron Variant

U.S. President Joe Biden says a highly transmissible COVID-19 variant, dubbed omicron, is a cause for “concern, not panic” and defended his much-criticized decision to restrict travel from the southern African region, where it was first reported. VOA’s Anita Powell reports from the White House.

WHO Calls for Renewed COVID Prevention Efforts Amid Omicron’s Spread

The World Health Organization says renewed efforts to prevent the spread of the coronavirus is needed as scientists scramble to determine the risks posed by the new omicron variant. Low vaccine rates combined with public fatigue over safety measures are putting more people in Africa at risk.

Experts say it’s no surprise a new variant of the coronavirus has been discovered.

Fewer than 8 percent of Africans are vaccinated against COVID-19, creating an environment for the illness to spread and mutate.

Dr. Mary Stephen is a technical officer for the World Health Organization’s Africa office. 

She said in the absence of vaccines, the public needs encouragement to uphold other measures to reduce the spread and save lives.

“We cannot be tired; we have to continue to make sure we are complying with wearing of our face masks, keeping our distance away, avoiding unnecessary mass gatherings, ensuring good hand hygiene, so that it’s another layer of protection in addition to the vaccination,” she said.

South African scientists detected the omicron variant last week.

Research is under way to determine how transmittable it is and its reaction to vaccines.

Amid uncertainty, Britain, the United States and European Union reacted by imposing travel bans to southern Africa.

Stephen, however, said the variant has already crossed continents and that halting flights to African countries that have long enforced testing for travelers is the wrong response. 

“The world should react to them with solidarity. The solution is not about banning travel but our ability to identify these cases, identify the potential risks, mitigate the risks, while we are still facilitating international travel because we have seen the devastating effects that COVID had on the economy,” she said.

Jeremiah Tshukudu is all too familiar with the economic toll of the pandemic.

The 45-year-old Uber driver said two of his cars were repossessed last year because he could no longer afford the payments during lockdown.

Tshukudu said he fears he’s about to take another financial hit with the new variant.

“I see us like losing close to let’s say 50% of what we’ve been earning recently. Relying on Uber, business was down, that means I wouldn’t be able to provide for the family,” he said.

Despite the pandemic’s impact on him, Tshukudu said he’s still hesitant about getting vaccinated.

With the threat of a new variant, experts are hoping people like him will reconsider.

Dr. Michelle Groome is with South Africa’s National Institute for Communicable Diseases. 

“Hopefully, you know, with some concern over coming fourth wave, hopefully, you know, those that were on the fence may actually go and vaccinate,” she said.

More than 3,200 people in South Africa tested positive for COVID-19 on Saturday, a marked increase from the day before.

The government is campaigning for more people to get vaccinated and even offering grocery vouchers to those who get their shot.

Government data show that at least 41 percent of South African adults have now been vaccinated.

Zimbabwe Says It’s Prepared for Omicron Variant

Zimbabwe’s government says the country is very prepared to handle the new COVID-19 variant – omicron – first reported in neighboring South Africa. The World Health Organization says a fourth wave of the pandemic is most likely to hit Africa.

Zimbabwe’s Vice President Constantino Chiwenga – who doubles as the country’s health minister – has asked the nation not to be concerned about omicron.

“The country should not panic because we are very prepared. The ramping up of our vaccination program in the past month has seen marked increase in the vaccination uptake. That is the prevention which we are going to have for our people if any other variant comes. At least when your body is protected it is much better than when you are found naked,” said the vice president.

Zimbabwe has fully inoculated about 2.8 million people since February, when it began its vaccination program to contain the COVID-19 pandemic. The government has a target of vaccinating at least 10 million Zimbabweans — or 60% of the population — by the end of the year, a figure which might be difficult to reach given the scarcity of resources and short time left.

Itai Rusike, head of the nonprofit Community Working Group on Health, said Zimbabweans should panic about the new variant – initially named B.1.1.529 – since the country shares porous borders with South Africa and Botswana.

“And this new variant is coming at a time when the festive season is upon us. A whole lot of Zimbabweans, they use undesignated entry points. That poses a serious health challenge as they would not be properly screened and monitored as they come back to the country. What we want to encourage the government of Zimbabwe, is for them to strengthen their surveillance and monitoring system especially the land borders and make sure that the screening and monitoring at the entry points is also strengthened,” said Rusike.

Meanwhile, Humphrey Karamagi, a medical officer at the World Health Organization Regional Office for Africa, said on the WHO Twitter account that a fourth wave of COVID-19 is likely to hit the continent.

“A fourth wave in Africa is almost a certainty, as long as we have these factors in play, which is new variants coming up and the fact that people can be reinfected. And also, if we are getting new population who may not have been exposed. We would then have subsequent waves. Vaccination helps a lot in terms of reducing the severity of the disease [and] also reducing the risk of infection. The vaccine is not a magic bullet. So the vaccine is to work together with the public health measures to reduce the potential and risks of subsequent waves,” said Karamagi.

The WHO says COVID-19 has infected about 6.1 million people in Africa and claimed 152,113 lives. The world health body also says more than 227 million vaccine doses have been administered in Africa.

COVID Variant Spreads to More Countries as World on Alert

The new potentially more contagious omicron variant of the coronavirus popped up in more European countries on Saturday, just days after being identified in South Africa, leaving governments around the world scrambling to stop the spread.

The U.K. on Saturday tightened its rules on mask-wearing and on testing of international arrivals after finding two cases. New cases were confirmed Saturday in Germany and Italy, with Belgium, Israel and Hong Kong also reporting that the variant has been found in travelers.

In the U.S., Dr. Anthony Fauci, the government’s top infectious diseases expert, said he would not be surprised if the omicron variant was already in the United States, too.

“We have not detected it yet, but when you have a virus that is showing this degree of transmissibility … it almost invariably is ultimately going to go essentially all over,” Fauci said on NBC television.

Because of fears that the new variant has the potential to be more resistant to the protection offered by vaccines, there are growing concerns around the world that the pandemic and associated lockdown restrictions will persist for far longer than hoped.

Nearly two years since the start of the pandemic that has claimed more than 5 million lives around the world, countries are on high alert. Many have already imposed travel restrictions on flights from southern Africa as they seek to buy time to assess whether the omicron variant is more transmissible than the current dominant delta variant.

In Britain, Prime Minister Boris Johnson said it was necessary to take “targeted and precautionary measures” after two people tested positive for the new variant in England.

“Right now this is the responsible course of action to slow down the seeding and the spread of this new variant and to maximize our defenses,” he told a news conference.

Among the measures announced, Johnson said anyone arriving in England must take a PCR test for COVID-19 on the second day after their arrival and self-isolate until they provide a negative test. And if someone tests positive for the omicron variant, then he said their close contacts will have to self-isolate for 10 days regardless of their vaccination status — currently close contacts are exempt from quarantine rules if they are fully vaccinated.

He also said mask-wearing in shops and on public transport will be required and said the independent group of scientists that advises the British government on the rollout of coronavirus vaccines has been asked to accelerate the vaccination program. This could involve widening the booster program to younger age groups, reducing the time period between a second dose and a booster and allowing older children to get a second dose.

“From today we’re going to boost the booster campaign,” he said.

 

Britain’s Department of Health said the two cases found in the U.K. were linked and involved travel from southern Africa. One of the two new cases was in the southeastern English town of Brentwood, while the other was in the central city of Nottingham. The two confirmed cases are self-isolating with their households while contact tracing and targeted testing takes place.

The British government also added four more countries — Angola, Malawi, Mozambique and Zambia — to the country’s travel red list from Sunday. Six others — Botswana, Eswatini (formerly Swaziland), Lesotho, Namibia, South Africa and Zimbabwe — were added Friday. That means anyone permitted to arrive from those destinations will have to quarantine.

Many countries have slapped restrictions on various southern African countries over the past couple of days, including Australia, Brazil, Canada, the European Union, Iran, Japan, New Zealand, Thailand and the United States, in response to warnings over the transmissibility of the new variant. This goes against the advice of the World Health Organization, which has warned against any overreaction before the variant was thoroughly studied.

Despite the banning of flights, there are mounting concerns that the variant has already been widely seeded around the world.

Italy and Germany were the latest to report confirmed cases of the omicron variant.

An Italian who had traveled to Mozambique on business landed in Rome on Nov. 11 and returned to his home near Naples. He and five family members, including two school-age children, have since tested positive, the Italian news agency LaPresse said. All are isolating in the Naples suburb of Caserta in good condition with light symptoms.

The variant was confirmed by Sacco hospital in Milan, and Italy’s National Health Institute said the man had received two doses of the vaccine. Italy’s health ministry is urging all regions to increase tracing of the virus and sequencing to detect cases of the new variant first identified in South Africa.

In Germany, the Max von Pettenkofer Institute, a Munich-based microbiology center, said the omicron variant was confirmed in two travelers who arrived on a flight from South Africa on Nov. 24. The head of the institute, Oliver Keppler, said that genome sequencing has yet to be completed, but it is “proven without doubt that it is this variant,” German news agency dpa reported.

 

The Dutch public health institute said the omicron variant was “probably found in a number of the tested persons” who were isolated after arriving Friday in Amsterdam on two flights from South Africa. The institute said in a statement that further sequencing analysis is underway to determine for sure that it is the new variant. The results were expected Sunday. A total of 61 people were tested.

Israel said it detected the new strain in a traveler who had returned from Malawi and was tracing 800 travelers who returned recently from southern African countries. And Australia said early Sunday its scientists were working to determine whether two people who tested positive for COVID after arriving from southern Africa are infected with the omicron variant.

The variant’s swift spread among young people in South Africa has alarmed health professionals even though there was no immediate indication whether the variant causes more severe disease.

Several pharmaceutical firms, including AstraZeneca, Moderna, Novavax and Pfizer, said they have plans in place to adapt their vaccines in light of the emergence of omicron. Pfizer and its partner BioNTech said they expect to be able to tweak their vaccine in around 100 days.

Professor Andrew Pollard, the director of the Oxford Vaccine Group, which developed the AstraZeneca vaccine, expressed cautious optimism that existing vaccines could be effective at preventing serious disease from the omicron variant, noting that most of the mutations appear to be in similar regions as those in other variants.

“At least from a speculative point of view we have some optimism that the vaccine should still work against a new variant for serious disease, but really we need to wait several weeks to have that confirmed,” he told BBC radio.

Some experts said the variant’s emergence illustrated how rich countries’ hoarding of vaccines threatens to prolong the pandemic.

Fewer than 6% of people in Africa have been fully immunized against COVID-19, and millions of health workers and vulnerable populations have yet to receive a single dose. Those conditions can speed up spread of the virus, offering more opportunities for it to evolve into a dangerous variant.

“One of the key factors to emergence of variants may well be low vaccination rates in parts of the world, and the WHO warning that none of us is safe until all of us are safe and should be heeded,” said Peter Openshaw, a professor of experimental medicine at Imperial College London.

U.S. Secretary of State Antony Blinken spoke Saturday with his South African counterpart, Naledi Pandor, and they stressed the importance of working together to help African nations vaccinate their populations, the State Department said in a statement. It said Blinken praised South Africa’s scientists for quickly identifying the omicron variant and the government for its transparency in sharing this information, “which should serve as a model for the world.”

US Praises South Africa’s Quick Detection, Sharing Variant Information

The United States praised South Africa on Saturday for quickly identifying the latest coronavirus variant, omicron, and sharing this information with the world.

Secretary of State Antony Blinken spoke with South Africa’s international relations and cooperation minister, Naledi Pandor, and they discussed cooperation on vaccinating people in Africa against COVID-19, the State Department said in a statement.

“Secretary Blinken specifically praised South Africa’s scientists for the quick identification of the omicron variant and South Africa’s government for its transparency in sharing this information, which should serve as a model for the world,” the statement said.

First detected in South Africa, the omicron variant of the coronavirus that causes COVID-19, was deemed by the World Health Organization a “variant of concern” on Friday.

Earlier Saturday, Pandor’s office issued a statement saying that the country is being punished for detecting the new variant as more countries rush to enact travel bans and restrictions.

By Saturday, more than a dozen countries had announced temporary travel restrictions on South Africa and other countries in the region after cases were reported in Europe and the Middle East.

FDA: Merck COVID pill effective, experts will review safety

Federal health regulators say an experimental COVID-19 pill from Merck is effective against the virus, but they will seek input from outside experts on risks of birth defects and other potential problems during pregnancy.

The Food and Drug Administration posted its analysis of the pill ahead of a public meeting next week where academic and other experts will weigh in on its safety and effectiveness. The agency isn’t required to follow the group’s advice.

The FDA scientists said their review identified several potential risks, including possible toxicity to developing fetuses and birth defects that were identified in studies of the pill in animals. 

Given those risks the FDA will ask its advisers next Tuesday whether the drug should never be given during pregnancy or whether it could be made available in certain cases.  

Under that scenario, the FDA said the drug would carry warnings about risks during pregnancy, but doctors would still have the option to prescribe it in certain cases where its benefits could outweigh its risks for patients.

Given the safety concerns, FDA said Merck agreed the drug would not be used in children.

Other side effects were mild and rare, with about 2% of patients experiencing diarrhea.

Regulators also noted that Merck collected far less safety data overall on its drug than was gathered for other COVID-19 therapies.

“While the clinical safety data base was small, there were no major safety concerns identified,” FDA reviewers concluded.

Additionally, the FDA flagged a concern that Merck’s drug led to small changes in the coronavirus’ signature spike protein, which it uses to penetrate human cells. 

Theoretically, FDA cautioned, those changes could lead to dangerous new variants.

FDA will ask its independent advisers to discuss all those issues and then vote on whether the drug’s overall benefits outweigh its risks.

All COVID-19 drugs currently authorized by the FDA require an injection or IV and can only be given by health professionals. If authorized, Merck’s drug would be the first that U.S. patients could take at home to ease symptoms and speed recovery. It is already authorized for emergency use in the U.K. 

The meeting marks the first time regulators have publicly reviewed a new drug for COVID-19, reflecting the intense interest and scrutiny of a pill that could be soon used by millions of Americans.

France Says it is Willing to Discuss Autonomy for Guadeloupe

France is willing to discuss autonomy for the French Caribbean territory of Guadeloupe if it is in the interests of the people who live there, government minister Sebastien Lecornu said.

Guadeloupe and the nearby French island of Martinique have seen several days of protests against COVID-19 measures that have spilled over into violence.

Lecornu, the minister for France’s overseas territories, said in a YouTube video issued late on Friday that certain elected officials in Guadeloupe had raised the question of autonomy, changing its status as an overseas region.

“The government is ready to talk about this. There are no bad debates, as long as those debates serve to resolve the real everyday problems of people in Guadeloupe,” he said.

That was one of a series of initiatives he said the government in Paris would be taking in Guadeloupe, including improving healthcare, infrastructure projects, and a scheme to create jobs for young people.

The French government this week announced that it would be postponing a requirement that public sector workers in Guadeloupe and Martinique get a COVID-19 vaccination.

That had sparked protests, fanning long-standing grievances over living standards and the relationship with Paris.

In Guadeloupe there is a historic mistrust of the French government’s handling of health crises after many people were exposed to toxic pesticides used in banana plantations in the 1970s.

India’s Serum Institute Resumes Vaccine Exports to COVAX Vaccine Sharing Program

The world’s largest vaccine maker, the Serum Institute of India has resumed exports of coronavirus vaccines to COVAX the partnership that is distributing vaccines to developing countries. The resumption of exports comes at a critical time when a new variant found in South Africa is causing concern around the world.

India suspended exports of vaccines in March this year following a severe surge in infections during the second wave of the COVID-19 pandemic as it used its stocks to ramp up its domestic inoculation program.

The first shipments went out Friday.

“This will go a long way in restoring vaccine supply equality in the world,” Serum Institute chief executive Adar Poonawalla said on Twitter.

The company said in a press statement that said that it expects the supply of vaccines to COVAX to increase substantially in early 2022. The Serum Institute of India was expected to be one of the main suppliers to the vaccine sharing facility which was created to ensure global equitable access to COVID-19 vaccines after the outbreak of the pandemic.

The Serum Institute linked the resumption of exports to surpassing its target of producing 1 billion doses of the AstraZeneca vaccine by the end of this year – it has produced 1.25 billion doses so far.

Gavi, the Vaccine Alliance, which leads the COVAX program along with the World Health Organization, called the restart of exports from India an important development “as it enters its busiest period yet for shipping vaccines to participating economies.”

The export curbs by India were a huge setback to efforts by COVAX, which had been relying on supplies of the affordable and easy to store AstraZeneca vaccine from India’s Serum Institute to distribute to low-income countries. The vaccine is called Covishield in India.

“While COVAX’s portfolio is now much more diversified than it was earlier this year when we received our first SII deliveries, COVISHIELD remains an important product which has the potential to help us protect hundreds of millions of people in the months ahead,” according to Seth Berkley, chief executive of GAVI, the Vaccine Alliance.

India has allowed exports to resume as its vaccination program makes substantial progress and vaccine supplies improve – about 80% of the country has received one dose and about 40% is fully vaccinated. Cases of coronavirus have also reduced dramatically – on Friday, India reported about 9,000 cases.

However, a new variant found in South Africa, dubbed omicron, is causing widespread concern and has prompted experts in India to caution against complacency. Designated a variant of concern by the World Health Organization, omicron has already been found in Belgium, Botswana, Israel and Hong Kong and has prompted several countries, including the United States and Britain to impose travel curbs.

India has said it is scaling up screening of passengers from overseas. At a meeting held Saturday to review the pandemic, Prime Minister Narendra Modi asked officials to review plans to ease international travel restrictions.

“In light of the new variant, we remain vigilant with a focus on containment and ensuring increased second dose coverage,” he tweeted.

Tourists Rush to South Africa Airport After Travel Bans Issued

Anxious-looking travelers thronged Johannesburg international airport and stood in long queues on Friday, desperate to squeeze onto the last flights to countries that had just shut their doors to South Africa.

Many cut short their holidays, rushing back from safaris and vineyards when Britain announced late Thursday night that all flights from South Africa and its neighbors would be banned the following day.

A flurry of nations — including the United States, Canada and several European countries — have followed suit, concerned about the discovery of a new coronavirus variant, renamed omicron, with several mutations fueling an infection resurgence in South Africa.

United Kingdom citizen Toby Reid, a 24-year-old trader in London, was camping on Cape Town’s Table Mountain with his girlfriend when the ban was announced.

“At about 5:30 a.m., we got up to see if we could catch the sunrise, and at six in the morning, we found out that there was still a possibility to get back,” he told AFP while standing in line for check-in at the Johannesburg airport just hours later.

The couple managed to grab the last two seats on an evening flight to Frankfurt, Germany.

Others who were not so lucky discussed options at ticket counters, eyes widening at proposed prices and convoluted itineraries.

“There should have been more notice,” muttered Christian Good, 50, returning to Devon, England, via Frankfurt with his husband after a beach holiday.

By chance, the pair had originally planned to return on that flight, meaning they would arrive home before mandatory hotel quarantine begins on Sunday — a requirement for citizens returning from “red list” countries.

“It’s ridiculous. We will always be having new variants,” his husband, David, exclaimed, passports in hand.

“South Africa found it, but it’s probably all over the world already,” he told AFP.

The variant has so far been detected in Belgium, Botswana, Israel and Hong Kong.

‘Tired of this’

At the airport, red “canceled” signs flashed next to London-bound flights listed on the departures board.

Other destinations were still in limbo.

A KLM flight to Amsterdam was delayed by several hours after passengers were suddenly compelled to produce negative COVID-19 results.

Rapid PCR tests were offered at the airport, with results guaranteed in two hours, but at a cost of $86, compared with the standard fee of around $52 for results delivered in roughly 12 hours.

An AFP correspondent observed Some African passport holders being told they would not be allowed to fly to Europe.

Earlier, travelers milled around a closed Air France check-in desk, waiting to find out whether an evening flight to Paris would take off as scheduled, just hours after France announced its own ban.

Among them were U.K. citizen Ruth Brown, 25, who lives in South Africa and had planned to return home for the first time since 2019 next week.

Britain kept South Africa on its red list until early October, meaning many of its citizens have been unable to travel back since the pandemic started because of the costly hotel quarantine.

They had only a few weeks of leeway before the status was revoked.

“We are tired of this situation,” said Brown, who spent the morning on the phone trying to change her flight.

“Apparently (this one) is full, but we are trying to see if we can still get seats,” she sighed.

Further down the line, Elke Hahn cradled a toddler.

She had traveled to South Africa with her partner to adopt the child and was desperate to get back to their home in Austria.

The child’s paperwork was only valid for a specific flight route that had since been changed.

“We will have to get another flight, but I don’t know how that will work,” she said.

Fauci: US Must Study Data Before Deciding on Travel Ban Over New COVID Variant

Top U.S. infectious disease official Anthony Fauci said Friday that a ban on flights from southern Africa was a possibility and the United States was rushing to gather data on the new COVID-19 variant. 

 

No decision to halt flights had yet been made, he said. The Wall Street Journal, citing people familiar with the matter, said White House officials were discussing potential travel restrictions on southern African countries. Those officials were expected to meet with agency officials Friday afternoon to make a recommendation, the newspaper said, without specifying which agency. 

 

The White House referred to Fauci’s earlier comments when asked about the report and declined further comment. Global authorities have reacted with alarm to the new variant, detected in South Africa, with the European Union and Britain among those tightening border controls as scientists seek to find out if the mutation is vaccine-resistant. 

 

The World Health Organization (WHO), however, has cautioned against hasty measures and South Africa said a British ban on flights seemed rushed. 

 

“There is always the possibility of doing what the UK has done, namely block travel from South Africa and related countries,” Fauci said in an interview on CNN. 

 

“That’s certainly something you think about and get prepared to do. You’re prepared to do everything you need to protect the American public. But you want to make sure there’s a basis for doing that,” he said. 

 

“Obviously as soon as we find out more information we’ll make a decision as quickly as we possibly can.”

 

Fauci said U.S. scientists would speak with South African counterparts Friday about the new variant, called B.1.1.529, which has raised concern about its transmissibility and whether it might evade immune responses. 

 

He added there was no indication the new variant was already in the United States.
