Experts are studying the question of whether people vaccinated against COVID will need a booster shot, and President Joe Biden’s administration is paying attention. “Requiring additional shots in the future is obviously a foreseeable potential event,” Andy Slavitt, who is on Biden’s COVID response team, said.

Research shows that shot’s ability to prevent disease wanes after six months. (Read more coronavirus vaccine stories.)
