CDC shortens interval for Pfizer booster, adds 3rd dose for immunocompromised kids

The Centers for Disease Control and Prevention has signed off on two measures to increase access to additional doses of the Pfizer coronavirus vaccine.

The CDC on Tuesday recommended shortening the recommended interval of time between when people who had an initial series of Pfizer vaccinations and when they receive a Pfizer booster shot, from six months to five months.

The agency has not changed the recommended booster interval for people who got other vaccines. The Johnson & Johnson booster interval is two months and the Moderna vaccine can be given six months after initial doses.

The CDC also recommended that kids ages 5 to 11 with moderately or severely weakened immune systems receive an additional dose 28 days after their second Pfizer shot. Currently, only the Pfizer vaccine is recommended for that age group.

The CDC’s decisions followed moves by the Food and Drug Administration on Monday. The FDA also approved Pfizer booster shots for kids ages 12 to 15. The CDC has not announced a recommendation about that, but a CDC expert advisory committee is expected to take up the matter during a meeting Wednesday.
