With coronavirus-positive hospitalizations increasing nationwide, some are asking whether a second COVID-19 booster shot will be made available to all younger adults under age 50. Currently, the U.S. Centers for Disease Control and Prevention recommends a second booster for anyone 50 and older, as well as immunocompromised people 12 and older, at least four months after a first booster. The CDC also recently recommended a first booster shot for children age 5 to 11 after completing their primary vaccination series. Officials and scientists have said the most convincing evidence to support a second booster shot has been seen in older adults and those with weakened immune systems; there have not been much data showing a benefit for younger adults. Jha said the data he has seen on the effectiveness of a second booster have been in older adults.
