The U.S. on Friday opened COVID-19 booster shots to all adults and took the extra step of urging people 50 and older to seek one, aiming to ward off a winter surge as coronavirus cases rise even before millions of Americans travel for the holidays.

Until now, Americans faced a confusing list of who was eligible for a booster that varied by age, their health and which kind of vaccine they got first. The Food and Drug Administration authorized changes to Pfizer and Moderna boosters that makes it easier.

Under the new rules, anyone 18 or older can choose either a Pfizer or Moderna booster six months after their last dose. For anyone who got the single-dose Johnson & Johnson vaccine, the wait already was just two months. And people can mix-and-match boosters from any company.

“We heard loud and clear that people needed something simpler — and this, I think, is simple,” FDA vaccine chief Dr. Peter Marks told The Associated Press.

The Centers for Disease Control and Prevention had to agree before the new policy became official late Friday. CDC Director Dr. Rochelle Walensky endorsed a recommendation from her agency’s scientific advisers that — in addition to offering all adults a booster — had stressed that people 50 and older should be urged to get one.

“It’s a stronger recommendation,” said CDC adviser Dr. Matthew Daley of Kaiser Permanente Colorado. “I want to make sure we provide as much protection as we can.”

The CDC also put out a plea for those who had previously qualified but hadn’t yet signed up for a booster to quit putting it off — saying older Americans and people with risks such as obesity, diabetes or other health problems should try to get one before the holidays.

The expansion makes tens of millions more Americans eligible for an extra dose of protection.

The No. 1 priority for the U.S., and the world, still is to get more unvaccinated people their first doses. All three COVID-19 vaccines used in the U.S. continue to offer strong protection against severe illness, including hospitalization and death, without a booster.

But protection against infection can wane with time, and the U.S. and many countries in Europe also are grappling with how widely to recommend boosters as they fight a winter wave of new cases. In the U.S., COVID-19 diagnoses have climbed steadily over the last three weeks, especially in states where colder weather already has driven people indoors.

And about a dozen states didn’t wait for federal officials to act before opening boosters to all adults.

“The direction is not a good one. People are going inside more and, ‘oops,’ next week happens to be the largest travel week of the year, so it probably makes sense to do whatever we can here to try to turn the tide,” Marks told the AP.

Vaccinations began in the U.S. last December, about a year after the coronavirus first emerged. More than 195 million Americans are now fully vaccinated, defined as having received two doses of the Pfizer or Moderna vaccines …read more
