The CDC said Americans 65 and older should get another dose of the updated vaccine that became available in September — if at least four months has passed since their last shot.

Some doctors say most older adults are adequately protected by the fall shot, which built on immunity derived from earlier vaccinations and exposure to the virus itself. And preliminary studies so far have shown no substantial waning in vaccine effectiveness over six months. In September, the government recommended a new COVID-19 shot recipe built against a version of the coronavirus called XBB.1.5. That single-target vaccine replaced combination shots that had been targeting both the original coronavirus strain and a much earlier omicron version.
"People are tired of getting all these shots all the time," said Canaday, who does not serve on the committee."We have to be careful about over-recommending the vaccine."
