As the US tries to stave off another Covid-19 surge this winter, health experts encourage anyone who is eligible to get a booster dose of vaccine do so.

About 10.7 million people have received a booster shot, including roughly 15% of seniors ages 65 and up, according to data from the US Centers for Disease Control and Prevention.

So far, only the Pfizer vaccine has been authorized for use as a booster for certain high-risk groups who received two doses of the Pfizer vaccine at least six months ago, the US Food and Drug Administration said.

Advisers to the FDA recently recommended booster doses for some people who got the Moderna or Johnson & Johnson vaccines.
