Covid: data is missing for more than 1 annual booster, says CDC – 02/25/2023 – Health

There is not enough evidence to recommend more than one booster dose of the Covid-19 vaccine per year for the elderly and people with weakened immune systems, said an advisory group of experts from the US Centers for Disease Control and Prevention (CDC). this Friday (24).

The Covid-19 working group of the CDC’s Advisory Committee on Immunization Practices (ACIP) has supported an annual booster campaign, likely in the fall, especially for populations considered to be at high risk, Sara Oliver said. , the CDC official who leads the group, during a meeting of the agency’s external advisors.

The agency currently recommends that the elderly and people with low immunity receive booster shots of the Covid vaccine more often, as the immunizer’s effectiveness generally declines more quickly for these populations compared to younger people with strengthened immune systems. .

During the spring of 2022 in the US, the CDC recommended that immunosuppressed people over the age of 50 receive an additional dose if they have already taken their first booster dose at least four months ago.

CDC consultants did not vote on new recommendations for administering doses of the Covid-19 vaccine on Friday.

But the ACIP advised showing flexibility in recommendations for people with compromised or weakened immune systems to allow for a higher frequency of doses for those most vulnerable to the severe form of Covid.
