Kennedy Jr. raised doubts about its efficacy. The US Food and Drug Administration cleared the shot for adults 65 and older and those ages 12 to 64 who have at least one underlying condition that puts them at high risk if they get the virus. The approval is a positive sign for other vaccine makers. It’s been unclear how their shots will fare under the leadership of Kennedy, a longtime vaccine critic.
