US Health Officials Are Asking Older Americans To Roll Up

Older U.S. adults should roll up their sleeves for another COVID-19 shot, even if they got a booster in the fall, U.S. health officials said Wednesday.

The Centers for Disease Control and Prevention said Americans 65 and older should get another dose of the updated vaccine that became available in September, if at least four months have passed since their last shot.

Other doctors have come out and said most older adults are adequately protected by the fall shot, which is built on immunity derived from earlier vaccinations and exposure to the virus itself.

Preliminary studies so far have shown no substantial waning in vaccine effectiveness over six months.
