To mask or not to mask is a question Italy settled early in the COVID-19 outbreak with a vigorous “yes.” Now the onetime epicenter of the pandemic in Europe hopes even stricter mask rules will help it beat the latest infection surge.

Other countries are taking similar action as the more transmissible — yet, apparently, less virulent — omicron variant spreads through the continent.

With Italy’s hospital ICUs rapidly filling with mostly unvaccinated COVID-19 patients, the government announced on Christmas Eve that FFP2 masks — which offer users more protection than cloth or surgical masks — must be worn on public transport, including planes, trains, ferries and subways.

That’s even though all passengers in Italy, as of this week, must be vaccinated or recently recovered from COVID-19. FFP2s also must now be worn at theaters, cinemas and sports events, indoors or out, and can’t be removed even for their wearers to eat or drink.

Italy re-introduced an outdoor mask mandate. It had never lifted its indoor mandate — even when infections sharply dropped in the summer.

On a chilly morning in Rome this week, Lillo D’Amico, 84, sported a wool cap and white FFP2 as he bought a newspaper at his neighborhood newsstand.

“(Masks) cost little money, they cost you a small sacrifice,” he said. “When you do the math, it costs far less than hospitalization.”

When he sees someone from the unmasked minority walking by, he keeps a distance. “They see (masks) as an affront to their freedom,” D’Amico said, shrugging.

Spain reinstated its outdoor mask rule on Christmas Eve. After the 14-day contagion rate soared to 2,722 new infections per 100,000 people by the end of last week — from 40 per 100,000 in mid-October — Prime Minister Pedro Sanchez was asked whether the outdoor mask mandate was helping.

“Of course, it is. It’s not me saying it. It’s science itself saying it because (it’s) a virus that is contracted when one exhales,” Sanchez said.

Portugal brought masks back at the end of November, after having largely dropped the requirement when it hit its goal of vaccinating 86% of the population.

Greece has also restored its outdoor mask mandate, while requiring an FFP2 or double surgical mask on public transport and in indoor public spaces.

This week the Dutch government’s outbreak management team recommended a mask mandate for people over 13 in busy public indoor areas such as restaurants, museums and theaters, and for spectators at indoor sports events. Those places are currently closed under a lockdown until at least Friday.

 

In France, the outdoor mask mandate was partially re-instated in December in many cities, including Paris. The age for children to start wearing masks in public places was lowered to 6 from 11.

Austrian Chancellor Karl Nehammer announced last week that people must wear FFP2 masks outdoors if they can’t keep at least 2 meters apart.

In Italy, with more than 2 million people currently positive for the virus in a nation of 60 million and workplace absences curtailing train and bus runs, the government also sees masks as a way to let society more fully function.

People with booster shots or recent second vaccine doses can now avoid quarantine after coming into contact with an infected person if they wear a FFP2 mask for 10 days.

The government has ordered shops to make FFP masks available for 85 U.S. cents. In the pandemic’s first year, FFP2s cost up to $11.50 — whenever they could be found.

Italians wear them in a palette of colors. The father of a baby baptized this week by Pope Francis in the Sistine Chapel wore one in burgundy, with matching tie and jacket pocket square. But the pontiff, who has practically shunned a mask in public, was maskless.

 

On Monday, Vatican City State mandated FFP2s in all indoor places. The tiny, walled independent state across the Tiber from the heart of Rome also stipulated that Vatican employees can go to work without quarantining after coming into contact with someone testing positive if, in addition to being fully vaccinated or having received a booster shot, they wear FFP2s.

Francis did appear to be wearing a FFP2 when, startling shoppers in Rome on Tuesday evening, he emerged from a music store near the Pantheon before being driven back to the Vatican.

In Britain, where Prime Minister Boris Johnson has focused on vaccination, masks have never been required outdoors.

This month, though, the government said secondary school students should wear face coverings in class. But Education Secretary Nadhim Zahawi said that rule wouldn’t apply “for a day longer than necessary.”

When the British government lifted pandemic restrictions in July 2021, turning mask-wearing from a requirement to a suggestion, mask use fell markedly.

Nino Cartabellotta, president of the Bologna-based GIMBE foundation, which monitors health care in Italy, says Britain points to what can happen when measures like mask-wearing aren’t valued.

“The situation in the U.K, showed that use of vaccination alone wasn’t enough” to get ahead of the pandemic, even though Britain was one of the first countries to begin vaccination, he said in a video interview.

Drones sprayed holy water from the Ganges on thousands of Hindu pilgrims on Friday to reduce crowding during a massive festival being held despite soaring COVID-19 cases in India.

The Gangasagar Mela in the east of the country has drawn comparisons with another “superspreader” Hindu gathering last year that the Hindu nationalist government refused to ban. It was blamed in part for a devastating COVID surge.

Officials had said they expected around 3 million people — including ash-smeared, dreadlocked ascetics — to attend the festival’s climax on Sagar Island, where the Ganges meets the Bay of Bengal.

“At the crack of dawn, there was a sea of people,” local official Bankim Hazra told AFP by telephone.

“Holy water from the river Ganges was sprayed from drones on pilgrims … to prevent crowding,” he said.

“But the saints and a large number of people were bent on taking the dip… Pilgrims, most of them without masks, outnumbered the security personnel.”

An AFP photographer said that there were fewer people than in recent years and that rain put off some pilgrims from making the journey.

But there were still huge crowds, mostly without masks, taking a holy dip in the river.

A police official on duty at the event said that it was “impossible” to enforce COVID restrictions.

“Most pilgrims are bent on defying the rules,” he said.

“They believe that God will save them and bathing at the confluence will cleanse all their sins and even the virus if they are infected.”

No lockdown

Fatalities from India’s current wave of infections remain a fraction of what they were during the surge in April and May last year, with 315 deaths recorded Thursday compared with as many as 4,000 per day at the peak.

Infections are rising fast, however, with almost 265,000 new cases Thursday. Some models predict India could experience as many as 800,000 cases per day in a few weeks, twice the rate seen nine months ago.

Keen to avoid another painful lockdown for millions of workers reliant on a few dollars in daily wages, authorities in different parts of India have sought to restrict gatherings.

In New Delhi, all bars, restaurants and private offices are shut, and the capital is set to go into its second weekend curfew on Friday night.

In the financial capital of Mumbai, gatherings of more than four people are banned.

But in West Bengal state, the Calcutta High Court on Friday allowed the Gangasagar Mela to proceed.

As with 2021’s Kumbh Mela, it has attracted people from across northern India who, after cramming onto trains, buses and boats to reach the island, will then go home — potentially taking the highly transmissible omicron virus variant with them.

Amitava Nandy, a virologist from the School of Tropical Medicines in Kolkata, said the government “has neither the facilities nor the manpower” to test everyone attending or impose social distancing.

“A stampede-like situation could happen if the police try to enforce social distancing on the riverbank,” Nandy told AFP.

Devotee Sarbananda Mishra, a 56-year-old schoolteacher from the neighboring state of Bihar, told AFP: “Faith in God will overcome the fear of COVID. The bathing will cleanse them of all their sins and bring salvation.

“Death is the ultimate truth. What is the point of living with fear?”

A 4-billion-year-old meteorite from Mars that caused a splash here on Earth decades ago contains no evidence of ancient, primitive Martian life after all, scientists reported Thursday. 

In 1996, a NASA-led team announced that organic compounds in the rock appeared to have been left by living creatures. Other scientists were skeptical, and researchers chipped away at that premise over the decades, most recently by a team led by the Carnegie Institution for Science’s Andrew Steele. 

Tiny samples from the meteorite show the carbon-rich compounds are actually the result of water — most likely salty, or briny, water — flowing over the rock for a prolonged period, Steele said. The findings appear in the journal Science. 

During Mars’ wet and early past, at least two impacts occurred near the rock, heating the planet’s surrounding surface, before a third impact bounced it off the red planet and into space millions of years ago. The 2-kilogram (4-pound) rock was found in Antarctica in 1984. 

Groundwater moving through the cracks in the rock, while it was still on Mars, formed the tiny globs of carbon that are present, according to the researchers. The same thing can happen on Earth and could help explain the presence of methane in Mars’ atmosphere, they said. 

But two scientists who took part in the original study took issue with these latest findings, calling them disappointing. In a shared email, they said they stand by their 1996 observations. 

“While the data presented incrementally adds to our knowledge of (the meteorite), the interpretation is hardly novel, nor is it supported by the research,” wrote Kathie Thomas-Keprta and Simon Clemett, astromaterial researchers at NASA’s Johnson Space Center in Houston. 

“Unsupported speculation does nothing to resolve the conundrum surrounding the origin of organic matter” in the meteorite, they added. 

According to Steele, advances in technology made his team’s new findings possible. 

He commended the measurements by the original researchers and noted that their life-claiming hypothesis “was a reasonable interpretation” at the time. He said he and his team, which includes NASA, German and British scientists, took care to present their results “for what they are, which is a very exciting discovery about Mars and not a study to disprove” the original premise. 

This finding “is huge for our understanding of how life started on this planet and helps refine the techniques we need to find life elsewhere on Mars, or Enceladus and Europa,” Steele said in an email, referring to Saturn and Jupiter’s moons with subsurface oceans. 

The only way to prove whether Mars ever had or still has microbial life, according to Steele, is to bring samples to Earth for analysis. NASA’s Perseverance Mars rover has collected six samples for return to Earth in a decade or so; three dozen samples are desired. 

Millions of years after drifting through space, the meteorite landed on an icefield in Antarctica thousands of years ago. The small gray-green fragment got its name — Allan Hills 84001 — from the hills where it was found.

The Supreme Court has stopped the Biden administration from enforcing a requirement that employees at large businesses be vaccinated against COVID-19 or undergo weekly testing and wear a mask on the job.

At the same time, the court is allowing the administration to proceed with a vaccine mandate for most health care workers in the U.S. 

The court’s orders Thursday during a spike in coronavirus cases was a mixed bag for the administration’s efforts to boost the vaccination rate among Americans. 

The court’s conservative majority concluded the administration overstepped its authority by seeking to impose the Occupational Safety and Health Administration’s vaccine-or-test rule on U.S. businesses with at least 100 employees. More than 80 million people would have been affected.

‘Never before’

“OSHA has never before imposed such a mandate. Nor has Congress. Indeed, although Congress has enacted significant legislation addressing the COVID-19 pandemic, it has declined to enact any measure similar to what OSHA has promulgated here,” the conservatives wrote in an unsigned opinion. 

In dissent, the court’s three liberals argued that it was the court that was overreaching by substituting its judgment for that of health experts. 

“Acting outside of its competence and without legal basis, the Court displaces the judgments of the Government officials given the responsibility to respond to workplace health emergencies,” Justices Stephen Breyer, Elena Kagan and Sonia Sotomayor wrote in a joint dissent. 

When crafting the OSHA rule, White House officials always anticipated legal challenges — and privately some harbored doubts that it could withstand them. The administration nonetheless still views the rule as a success at prompting millions of people to get vaccinated and private businesses to implement their own requirements that are unaffected by the legal challenge. 

Both rules had been challenged by Republican-led states. In addition, business groups attacked the OSHA emergency regulation as too expensive and likely to cause workers to leave their jobs at a time when finding new employees is difficult. 

The vaccine mandate that the court will allow to be enforced nationwide covers virtually all health care workers in the country. It applies to health care providers that receive federal Medicare or Medicaid funding, potentially affecting 76,000 health care facilities as well as home health care providers. The rule has medical and religious exemptions. 

Previously blocked in many states

Decisions by federal appeals courts in New Orleans and St. Louis had blocked the mandate in about half the states. The administration was taking steps to enforce it elsewhere. 

In the health care case, only Justices Clarence Thomas and Samuel Alito noted their dissents. 

“The challenges posed by a global pandemic do not allow a federal agency to exercise power that Congress has not conferred upon it. At the same time, such unprecedented circumstances provide no grounds for limiting the exercise of authorities the agency has long been recognized to have,” the justices wrote in an unsigned opinion, saying the “latter principle governs” in the health care cases. 

More than 208 million Americans, 62.7% of the population, are fully vaccinated, and more than a third of those have received booster shots, according to the U.S. Centers for Disease Control and Prevention. All nine justices have gotten booster shots. 

The justices heard arguments on the challenges last week. Their questions then hinted at the split verdict that they issued Thursday.

Two U.S. government agencies – space agency NASA, and the National Oceanic and Atmospheric Administration (NOAA), said Thursday 2021 was the sixth hottest year on record.

In separate reports, the agencies also said their data indicates the last eight years were the eight hottest since modern recordkeeping began. They also said global temperatures in 2021 were .85 degrees Celsius above the 20th century average. NOAA says last year was also the 45th year – since 1977 – average global temperatures rose above the 20th century average.

The agencies’ data shows global temperatures, averaged over a 10-year period to take out natural variability, are nearly 1.1 degrees Celsius warmer than 140 years ago.

In an interview with reporters, NOAA analysis chief Russell Vose said it is “warmer now than any time in at least the past 2,000 years, and probably much longer.” He predicted 2022 would also be among the warmest years ever.

Both agencies attributed weather anomalies from the past year, like melting sea ice, severe wildfires, and record flooding, as attributable to the warming climate.

NASA climate scientist Gavin Schmidt told the Associated Press the long-term trend is “very, very clear. And it’s because of us. And it’s not going to go away until we stop increasing the amount of carbon dioxide in the atmosphere.”

Some information for this report came from The Associated Press, and Reuters.

The risk of dying from cancer in the United States has fallen by nearly a third in three decades, thanks to earlier diagnoses, better treatments and less smoking, an analysis said Wednesday. 

The cancer death rate for men and women fell 32% from its peak in 1991 to 2019, the American Cancer Society said in its annual report. 

The drop represents about 3.5 million total deaths averted.

“This success is largely because of fewer people smoking, which resulted in declines in lung and other smoking-related cancers,” the report said, adding that lung cancer causes more deaths than any other kind. 

And the rate of decline is accelerating, data show. In the 1990s, the risk dropped 1% yearly. Between 2015 and 2019, the rate shrank twice as fast, about 2% a year. 

“Accelerating declines in the cancer death rate show the power of prevention, screening, early diagnosis, treatment and our overall potential to move closer to a world without cancer,” the cancer society report said. 

“In recent years, more people with lung cancer are being diagnosed when the cancer is at an early stage and living longer as a result,” it added. 

In 2004, only 21% of people diagnosed with lung cancer were still alive after three years. In 2018, the number grew to 31%. 

Disparities persist

Improving treatments and early screening are also helping to decrease death rates, but disparities in cancer outcomes persist. 

The cancer society reports that cancer survival rates are lower for Black people than for white people across almost every type of cancer. Black women are 41% more likely to die of breast cancer than white women, even though they are 4% less likely to get it. 

And American Indians and Alaska Natives have the highest liver cancer incidence of any major racial/ethnic group in the United States — a risk more than double that in white people. 

The cancer society attributes the gap to “inequities in wealth, education and overall standard of living,” stemming from “historical and persistent structural racism and discriminatory practices.” 

Additionally, the COVID-19 pandemic “greatly reduced” people’s ability to access cancer services, including prevention, detection and treatments, the organization said.

“These delays in care will probably worsen cancer disparities given the unequal burden the pandemic is having on communities of color,” the report warned, adding that the numbers do not account for the toll of the pandemic because the most recent data available are from 2019. 

Cancer is the second most common cause of death in the United States behind heart disease. 

In 2022, the cancer society expects 1.9 million new cancer cases and nearly 610,000 deaths, or about 1,670 deaths a day. 

According to the organization, 42% of the predicted cancer cases are “potentially avoidable,” since they can be caused by smoking, excess body weight, drinking alcohol, poor nutrition and physical inactivity. 

President Joe Biden, who lost his son Beau to brain cancer in 2015, wanted to make the fight against the disease a priority in his presidency, but it has so far been largely eclipsed by efforts to combat the COVID-19 pandemic.

The White House COVID-19 response team on Wednesday reminded Americans of the continued need to slow the omicron variant’s spread despite its decreased severity and announced new efforts to help keep schools open.

As the omicron variant sweeps across the U.S., Dr. Rochelle Walensky emphasized that wearing masks, getting vaccinated and undergoing COVID-19 testing when necessary are the best strategies to help lower cases of the virus.

Walensky, director of the U.S. Centers for Disease Control and Prevention, said the omicron variant accounted for 98% of new COVID-19 cases in the U.S. Earlier this week, the U.S. set a record for the number of daily infections at nearly 1.5 million, according to the Johns Hopkins Coronavirus Resource Center.

“All of us must do our part to protect our hospitals and our neighbors and reduce the further spread of this virus,” Walensky said.

The White House team also announced that the Biden administration would distribute 10 million tests to schools across the country each month to ensure they remain open, more than doubling the testing volume from last year.

Although the omicron variant is highly transmissible, it remains less severe than the delta variant, with a decreased risk of hospitalization and death.

Walensky, citing a recent study comparing the two variants, said omicron infections were associated with a 91% reduction in the risk of death and a 74% reduction in the risk of ICU admission.

She also said that infections with the variant had a 53% reduced risk of symptomatic hospitalization.

More hospitalizations

While the risk of hospitalization remains low, the “staggering rise in cases” has increased the country’s number of hospitalizations, according to Walensky.

Nonetheless, she said, patients infected with omicron are experiencing 71% shorter hospital stays than those infected with the delta variant.

On average, omicron patients are hospitalized for about 1.5 days and 90% are expected to be discharged in three days or less.

As the surge continues, Walensky reiterated that cases of the variant are expected to peak in the coming weeks. She also said deaths have increased, with more than 2,600 reported by John Hopkins on Wednesday.

Dr. Anthony Fauci, the top U.S. infectious-disease expert, said the country would not be able to eliminate or eradicate COVID-19, but would “ultimately control it.” As the virus becomes endemic, it is likely that “virtually everybody is going to wind up getting exposed and likely get infected,” he said.

However, he added, this does not mean that vaccinations or preventative measures are ineffective or pointless. Fauci clarified that getting vaccinated and staying up to date with booster shots will prevent serious illness from the disease.

“If you’re vaccinated and if you’re boosted, the chances of your getting sick are very, very low,” Fauci said.

To help battle the current surge, the White House team stressed that mitigation efforts remain critical, including wearing a mask. While N95 masks have been shown to be the most effective in resisting airborne transmission of the virus, the CDC still recommends that, for the time being, people choose the mask that is right for them, and that wearing any well-fitting mask is better than no mask.

“We want to highlight that the best mask for you is the one that you can wear comfortably,” Walensky said.

Jeffrey D. Zients, the White House’s COVID-19 response coordinator, was asked about finding masks and said the administration is “strongly considering options to make more high-quality masks available to all Americans.”

As for schools, the team said that, along with increased testing, vaccination and other mitigation efforts are the keys to keeping students in the classroom.

Walensky stated that with pediatric vaccines now available, schools should be able to continue operating as planned. She also reminded reporters that 99% of schools remained open in the fall during a surge in the delta variant.

“One of the best things we can do is get our children and our teenagers vaccinated,” she said.

From a seaside perch overlooking the hustle and bustle of ships coming and going at Port Canaveral on Florida’s east coast, Dale Ketcham reflects on decades of history with nostalgia.

 

“I moved here and learned how to walk on Cocoa Beach three years before NASA was created” in 1958, he said.

 

Not only can Ketcham trace his life alongside the U.S. space program, he’s had a firsthand view of the transformation of the economies of communities surrounding NASA’s Kennedy Space Center several times since the 1950s.

 

“The space program continued to progress, but it was always government-focused,” said Ketcham, adding that the configuration did not bring long-term stability to the local workforce.

“For 50 years roughly, Florida’s Space Coast was the place for launch” but not production of spacecraft, said Brian Baluta of the Economic Development Commission (EDC) of Florida’s Space Coast.

 

Most of the equipment used in the Apollo and space shuttle programs in the last half of the 20th century was shipped to Florida for assembly.When Atlantis touched down in 2011 on the final shuttle mission, it marked the end of an era in human spaceflight, with painful economic consequences for the Space Coast.

 

“The job losses started to pile up, and that happened to coincide with the Great Recession,” Baluta said.“And that was really a one-two punch for this area. In 2011, unemployment was 12% at that point. The economy and its outlook (were) not that strong.”

 

Baluta’s organization responded by forging a plan to boost the fortunes of the area’s workforce — permanently.

 

“It started with taking the unusual step of reaching out to the companies who were likely to produce the successor to the space shuttle,” he said.“At the time, it was called the Crew Exploration Vehicle, and there wasn’t a contract for it yet,” he said. “But we reached out to Lockheed Martin, Northrop Grumman, Boeing — the companies that would likely compete and win for that contract. And we made the unusual pitch of, ‘If you win the contract, not only should you consider launching from Cape Canaveral, but you should consider assembling your spacecraft here.’”

Diversify products 

 

The concept took off.

 

“Just like diversifying a portfolio, if you diversify the area and your products, you can ride through those lows,” said Lockheed Martin’s Kelly DeFazio. Her company won the contract to create NASA’s next-generation spacecraft transporting humans back to the moon.

The Crew Exploration Vehicle, now called Orion, is the crew capsule of the upcoming Artemis missions. Instead of making them elsewhere, some of Orion’s key components are pieced together at Lockheed Martin’s new STAR (Spacecraft, Test, Assembly and Resource) Center near Titusville, Florida, which is the former home of Space Camp and the U.S. Astronaut Hall of Fame.

“This particular center here was an 18-month, $20 million investment by Lockheed Martin, and that is helping to expand the manufacturing footprint for the Space Coast and allowing us to increase throughput (output) over time to support the lunar mission,” said DeFazio, who is also a longtime resident of Florida’s Space Coast. She now oversees the work at STAR Center, which includes creating wiring harnesses and the application of thermal tiles that will protect the Orion capsule.

Amid all the activity at STAR Center, DeFazio said local excitement is building.

 

“I think that it will start to become very clear with the launch of Artemis 1 that there is a difference,” said DeFazio. “And you know what? We’re going to take humans farther than they have ever gone before.”

 

“When I was growing up with the original seven astronauts, it was really a frontier town,” Ketcham said. That Wild West frontier town description is also how he characterizes the present-day Space Coast, with government contractors and private companies jockeying for real estate and launch access. 

“In many ways, we’re going back. … The workforce is younger, particularly with Space X. They aren’t afraid to fail,” Ketcham said. 

‘The more the merrier’ 

 

Space X, Blue Origin, and the Airbus and One Web partnership are just a few of the growing number of companies now with facilities near the rocket launch pads at Kennedy Space Center, thanks in part to the efforts of the EDC and organizations like Space Florida, where Ketcham now serves as vice president.

 

“We just had an announcement this week that there will be a small launch company called Astra coming here to build small rockets for small satellites, which is a big new component of the space industry,” said Ketcham. “But we’ve also got Firefly, Relativity coming — and others will be coming after that.”

 

The more the merrier said Ketcham, who believes the flurry of activity not only helps the local economy but also keeps the United States competitive globally in what he sees as a new international space race.

China leading the race 

“The Chinese will put more rockets into orbit than we will because the Chinese are competitive, very smart, very capable, very well-resourced and very committed. And they are the major competitors in space,” Ketcham said. 

NASA Administrator Bill Nelson agrees.

 

During a U.S. House of Representatives appropriations hearing conducted remotely last year, he signaled alarm over the recent successes in the Chinese space program, including landing a rover on the surface of Mars, and is concerned that their ambitions are not limited to the red planet.

“They want to send three big landers to the south pole of the moon,” Nelson told members of Congress. “And that’s where the water is. And we are still a year or two away from a much smaller lander going there.”

 

Nelson wants U.S. lawmakers to increase NASA’s funding so the agency can complete the Artemis program, which plans to return humans — including the first woman — to the moon, with Mars as an eventual destination.

 

“I think that’s adding a new element as to whether or not we want to get serious and get a lot of activity going on landing humans back on the surface of the moon,” he said.

The common cold can provide some protection from COVID-19, according to new research led by Imperial College London, which says the findings provide a blueprint for future vaccines that could offer immunity to all variants of the coronavirus. 

Since the start of the pandemic, scientists have questioned why some people are able to resist coronavirus infection despite prolonged exposure, while others are easily infected. The researchers set out to test a theory that a type of white blood cells called T cells, produced by the human body to fight the cold, could offer some protection.

“Previous infection with common cold coronaviruses — these are distantly related cousins of SARS-CoV-2 which causes COVID-19 — infection with those might induce T cells that would be able to cross-recognize and then attack the SARS-CoV-2 virus. That was the theory that we set about to test,” report co-author Ajit Lalvani, chair in infectious diseases at Imperial College London, said in an interview with VOA.

The study began in September 2020 before any mass vaccination programs and before most people had been infected with COVID-19.

Scientists sampled the blood of 52 people who lived in the same household as they would someone infected with the SARS-CoV-2 virus. The sampling took place immediately after the COVID-19 diagnosis was confirmed.

Exactly half of those sampled contracted COVID-19, while the others did not. 

“Those contacts who had preexisting T cells that were induced by common cold coronavirus (and which could) cross-recognize and attack SARS-CoV-2 people with such T cells didn’t get infected,” Lalvani said.

Current COVID-19 vaccines are designed to trigger an immune response that targets the spike proteins on the outside of the coronavirus, which are easily able to mutate and escape immunity.

“In contrast, the T cells we discovered that mediate this protection are directed against proteins in the core of the virus, internal proteins,” Lalvani said. “And these proteins are much less changeable. So essentially, our findings provide the blueprint for producing a universal T cell-inducing vaccine to protect people against current and all future variants of COVID-19.”

Development of such a vaccine remains some way off. Meanwhile, the report’s authors emphasize that no one should rely on a common cold infection to provide immunity against COVID-19. 

“Not least because the coronavirus only causes a proportion of the common cold. Maybe one-fifth or so of common colds are due to coronaviruses, and the remainder due to other types of cold-causing viruses,” Lalvani said. 

“And in any case, whether you’ve had a coronavirus common cold or not — and you’d have no way of knowing — you should still get double-vaccinated and have your booster,” he said.
