new york — Older U.S. adults should roll up their sleeves for another COVID-19 shot, even if they got a booster in the fall, U.S. health officials said Wednesday.

The Centers for Disease Control and Prevention said Americans 65 and older should get another dose of the updated vaccine that became available in September — if at least four months has passed since their last shot. In making the recommendation, the agency endorsed guidance proposed by an expert advisory panel earlier in the day.

“Most COVID-19 deaths and hospitalizations last year were among people 65 years and older. An additional vaccine dose can provide added protection … for those at highest risk,” CDC Director Dr. Mandy Cohen said in a statement.

The advisory panel’s decision came after a lengthy discussion about whether to say older people “may” get the shots or if they “should” do so. That reflects a debate among experts about how necessary another booster is and whether yet another recommendation would add to the public’s growing vaccine fatigue.

Some doctors say most older adults are adequately protected by the fall shot, which built on immunity derived from earlier vaccinations and exposure to the virus itself. And preliminary studies so far have shown no substantial waning in vaccine effectiveness over six months.

However, the body’s vaccine-induced defenses tend to fade over time, and that happens faster in seniors than in other adults. The committee had recommended COVID-19 booster doses for older adults in 2022 and 2023.

Virus still a threat

COVID-19 remains a danger, especially to older people and those with underlying medical conditions. There are still more than 20,000 hospitalizations and more than 2,000 deaths each week due to the coronavirus, according to the CDC. And people 65 and older have the highest hospitalization and death rates.

Some members of the advisory panel said a “should” recommendation is meant to more clearly prod doctors and pharmacists to offer the shots.

Dr. Jamie Loehr, a committee member and family doctor in Ithaca, New York, said that with the “should” recommendation, “I am trying to make it easier for providers to say, ‘Yes, we recommend this.'”

In September, the government recommended a new COVID-19 shot recipe built against a version of the coronavirus called XBB.1.5. That single-target vaccine replaced combination shots that had been targeting both the original coronavirus strain and a much earlier omicron version.

Vaccine uptake has declined

The CDC recommended the new shots for everyone 6 months and older and allowed that people with weak immune systems could get a second dose as early as two months after the first.

Most Americans haven’t listened. According to the latest CDC data, 13% of U.S. children have gotten the shots and about 22% of U.S. adults have. The vaccination rate is higher for adults 65 and older, at nearly 42%.

“In each successive vaccine, the uptake has gone down,” said Dr. David Canaday, a Case Western Reserve University infectious-diseases expert who studies COVID-19 in older people.

“People are tired of getting all these shots all the time,” said Canaday, who does not serve on the committee. “We have to be careful about over-recommending the vaccine.”

But there is a subset of Americans — those at higher danger of severe illness and death — who have been asking if another dose is permissible, said Dr. William Schaffner, a Vanderbilt University vaccines expert who serves on a committee workgroup that has been debating the booster question.

Indeed, CDC survey data suggest that group’s biggest worry about the vaccine is whether it’s effective enough.

Agency officials say that among those who got the latest version of the COVID-19 vaccine, 50% fewer will get sick after they come into contact with the virus compared with those who didn’t get the fall shot.

washington — U.S. President Joe Biden’s is a “healthy, active, robust 81-year-old male who remains fit to successfully execute the duties of the presidency,” his physician, Dr. Kevin O’Connor, said in a statement released by the White House on Wednesday, following Biden’s annual physical examination. 

“The president feels well, and this year’s physical identified no new concerns. He continues to be fit for duty and fully executes all of his responsibilities without any exemptions or accommodations,” O’Connor said following Biden’s visit to Walter Reed National Military Medical Center in Bethesda, Maryland, earlier Wednesday.  

The checkup included consultations with optometry, dentistry, orthopedics, physical therapy, neurology, sleep medicine, cardiology, radiology and dermatology specialists, O’Connor said.  

It’s Biden’s third physical since taking office, amid concerns about his age as he seeks a second term.  

“They think I look too young,” Biden joked to reporters at the White House after his checkup. “There is nothing different than last year,” he said.

According to the summary, Biden is currently being treated for several conditions, including obstructive sleep apnea, gastroesophageal reflux, seasonal allergies, arthritis and sensory peripheral neuropathy of the feet. He also has atrial fibrillation with normal ventricular response, a type of asymptomatic irregularity of the heartbeat.  

His doctor pronounced his conditions as “stable and well-controlled,” with “three common prescription medications and three common over-the-counter medications.”  

The symptoms were similar to those described in Biden’s 2023 physical exam report that noted the president’s “stiff gait,” due to “a combination of significant spinal arthritis, mild post-fracture foot arthritis and a mild sensory peripheral neuropathy of the feet,” and “occasional symptoms of gastroesophageal reflux,” that made him have to clear his throat often.     

President didn’t undergo cognitive test 

Recent events have highlighted Biden’s potential age-related issues, including the president being described in a special counsel report as an “elderly man with a poor memory.”      

In pushing back on reporters’ questions about his age, Biden insisted that his “memory is fine” but shortly after mistakenly referred to Egyptian President Abdel Fattah el-Sissi as the president of Mexico. That and two other mistaken references to world leaders’ names in recent weeks fueled further attacks by his rivals.     

Responding to reporters’ questions during her briefing on Wednesday, White House press secretary Karine Jean-Pierre said Biden did not undergo a cognitive test as part of his physical because the president’s physician, “doesn’t believe that he needs one.” 

As president, Biden passes a cognitive test “every day,” Jean-Pierre underscored. 

A poll by the George Washington University shows 35% of respondents say Biden was in good enough physical health to serve effectively as president, and 38% said he has the mental soundness to serve effectively as president.  

This is lower that what respondents say about the leading candidate for the Republican presidential nomination, Donald Trump, who is four years younger. For Trump, the numbers are 54% and 46%, respectively. 

“These figures indicate that this is a big problem for Biden,” Todd Belt, professor of politics at George Washington University, told VOA. “The campaign has changed course to attack Trump on his vulnerabilities on the mental soundness issue.” 

Biden did exactly that during an appearance on a late-night television show earlier this week, by referencing a video in which Trump appeared to forget his wife’s name.  

Americans concerned about Biden’s age

Trump was 70 when he took office in 2017, which made him the oldest American president to be inaugurated until Biden broke his record at 78 in 2021. The former president has also made blunders, including praising Hungarian Prime Minister Viktor Orban for his leadership of Turkey, and confusing his Republican rival, Nikki Haley, with former U.S. House Speaker Nancy Pelosi.   

A February ABC News/Ipsos poll conducted after the release of the special counsel report indicated concerns among 59% of Americans regarding the age and capability for a second term for both candidates, although more Americans are worried about Biden compared with Trump, said Clifford Young, president of Ipsos Public Affairs.   

“Age is an Achilles’ heel, is an anchor for Biden,” Young told VOA. “It was four years ago. Without a doubt, it will be this year.”   

Though not publicly announced in advance, the timing of Biden’s physical was anticipated, given the increasing focus on his age and health in the context of his reelection campaign ahead of the November election.

WASHINGTON — Democrats on Wednesday failed in an attempt to rush legislation through the U.S. Senate guaranteeing Americans’ access to in vitro fertilization and other assisted reproductive technologies, after an Alabama court designated frozen embryos as children.

The state Supreme Court ruling on February 16 that frozen embryos should be considered children prompted at least three Alabama providers to halt the IVF procedure that involves combining eggs and sperm in a laboratory dish for couples having difficulty conceiving.

Alabama’s court ruling has raised concerns that those involved in IVF could face prosecution because embryos that are found to be nonviable are sometimes disposed of or used for research, and that it could encourage other states to follow suit.

Democratic Senator Tammy Duckworth, an Iraq War veteran who suffered grave injuries in combat in 2004, sought an immediate vote by the Senate on Wednesday on passage of her “Access to Family Building Act” legislation.

Her move for a vote, which required the consent of all 100 senators, was promptly blocked by Republican Senator Cindy Hyde-Smith.

“The bill before us today is a vast overreach that is full of poison pills that goes way too far, far beyond ensuring legal access to IVF,” Hyde-Smith said.

Duckworth countered that her bill simply would guarantee access to IVF treatments and facilities “without fear of being prosecuted,” while also shielding IVF providers and health insurance companies.

While many Republican officeholders have expressed discomfort with the Alabama court ruling, the party was not ready to fall in line with Democrats on this hot-button issue that is linked to the national debate over women’s right to abortion.

Duckworth told reporters on Tuesday that she struggled for a decade with infertility following her military service in Iraq, which prompted her and her husband to turn to IVF. They now have two children.

“I have five embryos that were created (using IVF); three that were deemed to be nonviable, would not survive,” Duckworth said.

She said that at the time, in 2013, her doctor told her that if “personhood laws” regarding embryos were to be enacted, “I could be convicted of manslaughter or murder for discarding these three eggs that were nonviable.”

Reproductive rights are expected to be a major issue in this year’s presidential and congressional campaigns, with Democrats lashing out at both the U.S. Supreme Court’s 2022 ruling overturning its landmark Roe v. Wade case establishing a national right to abortion, as well as subsequent state reproductive rights actions such as the one on IVF.

In a statement Wednesday, White House spokesperson Karine Jean-Pierre said the Republican blocking of Duckworth’s measure was “outrageous.”

Jean-Pierre added that President Joe Biden and Vice President Kamala Harris “will continue to fight to protect access to reproductive health care, including IVF, and call on Congress to restore the protections of Roe v. Wade in federal law for all women in every state.”

NEW YORK — Leap year. It’s a delight for the calendar and math nerds among us. So how did it all begin and why?

Have a look at some of the numbers, history and lore behind the (not quite) every four-year phenom that adds a 29th day to February.

By the numbers

The math is mind-boggling in a layperson sort of way and down to fractions of days and minutes. There’s even a leap second occasionally, but there’s no hullabaloo when that happens.

The thing to know is that leap year exists, in large part, to keep the months in sync with annual events, including equinoxes and solstices, according to the Jet Propulsion Laboratory at the California Institute of Technology.

It’s a correction to counter the fact that Earth’s orbit isn’t precisely 365 days a year. The trip takes about six hours longer than that, NASA says.

Contrary to what some might believe, however, not every four years is a leaper. Adding a leap day every four years would make the calendar longer by more than 44 minutes, according to the National Air & Space Museum.

Later, on a calendar yet to come (we’ll get to it), it was decreed that years divisible by 100 not follow the four-year leap day rule unless they are also divisible by 400, the JPL notes. In the past 500 years, there was no leap day in 1700, 1800 and 1900, but 2000 had one. In the next 500 years, if the practice is followed, there will be no leap day in 2100, 2200, 2300 and 2500.

Still with us?

The next leap years are 2028, 2032 and 2036.

What would happen without a leap day?

Eventually, nothing good in terms of when major events fall, when farmers plant and how seasons align with the sun and the moon.

“Without the leap years, after a few hundred years we will have summer in November,” said Younas Khan, a physics instructor at the University of Alabama at Birmingham. “Christmas will be in summer. There will be no snow. There will be no feeling of Christmas.”

Who came up with leap year?

The short answer: It evolved.

Ancient civilizations used the cosmos to plan their lives, and there are calendars dating back to the Bronze Age. They were based on either the phases of the moon or the sun, as various calendars are today. Usually they were “lunisolar,” using both.

Now hop on over to the Roman Empire and Julius Caesar. He was dealing with major seasonal drift on calendars used in his neck of the woods. They dealt badly with drift by adding months. He was also navigating many calendars starting in many ways in the vast Roman Empire.

He introduced his Julian calendar in 46 BCE. It was purely solar and counted a year at 365.25 days, so once every four years an extra day was added. Before that, the Romans counted a year at 355 days, at least for a time.

But still, under Julius, there was drift. There were too many leap years! The solar year isn’t precisely 365.25 days! It’s 365.242 days, said Nick Eakes, an astronomy educator at the Morehead Planetarium and Science Center at the University of North Carolina in Chapel Hill.

Thomas Palaima, a classics professor at the University of Texas at Austin, said adding periods of time to a year to reflect variations in the lunar and solar cycles was done by the ancients. The Athenian calendar, he said, was used in the fourth, fifth and sixth centuries with 12 lunar months.

That didn’t work for seasonal religious rites. The drift problem led to “intercalating” an extra month periodically to realign with lunar and solar cycles, Palaima said.

The Julian calendar was 0.0078 days (11 minutes and 14 seconds) longer than the tropical year, so errors in timekeeping still gradually accumulated, according to NASA. But stability increased, Palaima said.

The Julian calendar was the model used by the Western world for hundreds of years. Enter Pope Gregory XIII, who calibrated further. His Gregorian calendar took effect in the late 16th century. It remains in use today and, clearly, isn’t perfect or there would be no need for leap year. But it was a big improvement, reducing drift to mere seconds.

Why did he step in? Well, Easter. It was coming later in the year over time, and he fretted that events related to Easter like the Pentecost might bump up against pagan festivals. The pope wanted Easter to remain in the spring.

He eliminated some extra days accumulated on the Julian calendar and tweaked the rules on leap day. It’s Pope Gregory and his advisers who came up with the really gnarly math on when there should or shouldn’t be a leap year.

“If the solar year was a perfect 365.25 then we wouldn’t have to worry about the tricky math involved,” Eakes said.

What’s the deal with leap year and marriage?

Bizarrely, leap day comes with lore about women popping the marriage question to men. It was mostly benign fun, but it came with a bite that reinforced gender roles.

There’s distant European folklore. One story places the idea of women proposing in fifth century Ireland, with St. Bridget appealing to St. Patrick to offer women the chance to ask men to marry them, according to historian Katherine Parkin in a 2012 paper in the Journal of Family History.

Nobody really knows where it all began.

In 1904, syndicated columnist Elizabeth Meriwether Gilmer, aka Dorothy Dix, summed up the tradition this way: “Of course people will say … that a woman’s leap year prerogative, like most of her liberties, is merely a glittering mockery.”

The pre-Sadie Hawkins tradition, however serious or tongue-in-cheek, could have empowered women but merely perpetuated stereotypes. The proposals were to happen via postcard, but many such cards turned the tables and poked fun at women instead.

Advertising perpetuated the leap year marriage game. A 1916 ad by the American Industrial Bank and Trust Co. read thusly: “This being Leap Year day, we suggest to every girl that she propose to her father to open a savings account in her name in our own bank.”

There was no breath of independence for women due to leap day.

Should we pity the leaplings?

Being born in a leap year on a leap day certainly is a talking point. But it can be kind of a pain from a paperwork perspective. Some governments and others requiring forms to be filled out and birthdays to be stated stepped in to declare what date was used by leaplings for such things as drivers’ licenses, whether Feb. 28 or March 1.

Technology has made it far easier for leap babies to jot down their Feb. 29 milestones, though there can be glitches in terms of health systems, insurance policies and with other businesses and organizations that don’t have that date built in.

There are about 5 million people worldwide who share the leap birthday out of about 8 billion people on the planet. Shelley Dean, 23, in Seattle, Washington, chooses a rosy attitude about being a leapling. Growing up, she had normal birthday parties each year, but an extra special one when leap years rolled around. Since, as an adult, she marks that non-leap period between Feb. 28 and March 1 with a low-key “whew.”

This year is different.

“It will be the first birthday that I’m going to celebrate with my family in eight years, which is super exciting, because the last leap day I was on the other side of the country in New York for college,” she said. “It’s a very big year.”

New Delhi — Indian Prime Minister Narendra Modi on Tuesday toasted the four astronauts preparing for the nation’s first crewed orbital mission, saying the latest advance in spacefaring would inspire the next generation.

“The countdown of the rocket inspires thousands of children in India, and those making paper planes today dream of becoming scientists like you,” Modi said. 

The Gaganyaan — or “Skycraft” — mission is slated to launch the astronauts into Earth’s orbit in 2025, an important measure of the Indian Space Research Organization’s technical capabilities.

“All of you are opening new doors of future possibilities,” Modi told ISRO scientists on Tuesday.

Visiting the Vikram Sarabhai Space Centre in the southern state of Kerala, Modi presented “astronaut wings” to the four men: Ajit Krishnan, Prashanth Balakrishnan Nair, Angad Pratap and Shubhanshu Shukla.

“They are not just four names or individuals, they are four ‘shakti’ [the Hindu goddess of power] carrying the aspirations of 1.4 billion Indians into space,” he added.

Gaganyaan is the first mission of its kind for India and comes with an estimated price tag of $1.08 billion, according to ISRO.

India plans to send the quartet beyond the reaches of Earth’s atmosphere for three days before bringing them back with a soft landing in its territorial waters.

Modi has previously announced plans to launch a space station by 2034, and to put people on the moon by 2040.

In August, India became just the fourth nation to land an unmanned craft on the moon, after Russia, the United States and China.

The following month, it launched a probe to observe the outermost layers of the sun from solar orbit.

India’s space program has grown considerably in size and momentum since it first sent a probe to orbit the moon in 2008, and it has steadily matched the achievements of established spacefaring powers, at a fraction of the cost.

India can keep costs low by copying and adapting existing technology, and tapping an abundance of highly skilled engineers who earn a fraction of their foreign counterparts’ wages.
