On
Friday, federal health officials OK'd
boosters for every US adult who got Moderna's or Pfizer/BioNTech's Covid-19
vaccine six months ago or more. The
agencies had previously said everyone who got Johnson & Johnson's vaccine
two months ago or more should get a booster. But Friday's decision means
everyone 18 and older who is fully vaccinated should consider getting another
dose of vaccine. Previous
guidance was more complicated, and vaccine advisers to the US Centers of
Disease Control and Prevention expressed concern that people who should be
receiving a booster weren’t getting one. "If
you're 18 or older and you've been vaccinated -- fully vaccinated with the
Moderna or the Pfizer mRNA six months or more ago -- get a booster. If it's
J&J and it's two months ago, or more, get a booster," Dr. Anthony
Fauci, director of the National Institute of Allergy and Infectious Diseases,
said on CNN Sunday. Recent
real-world studies suggest that immunity from Covid-19 vaccines begins to
wane, and protection against milder and asymptomatic disease -- in particular
-- may drop. Studies have shown that booster doses restore that immunity. And it doesn’t
matter which vaccine you get to boost. People who got two doses of
Pfizer's vaccine may either get a third dose of it, or they may opt for a
Moderna booster, which is a half-size dose of the first two Moderna shots; or
they can get a Johnson & Johnson booster. The same goes for all the
vaccines. "Just
go out and get boosted. We know they're safe and we know they're highly
effective in bringing very, very high up the optimization of your protection.
So just go ahead and get boosted. Now's the time to do it as we get into the
holiday season,” Fauci said. |
