CDC director Rochelle Walensky’s early morning announcement on Sept. 24 recommending boosters for certain frontline workers was considered wise by some but as undermining her advisers and the process by others. She endorsed the Advisory Committee on Immunization Practices’ recommendation for booster doses of the Pfizer Inc.-Biontech SE COVID-19 vaccine but overruled one of the panel’s Sept. 23 decisions by adding boosters for people ages 18 to 64 who are at increased risk of COVID-19 exposure and transmission due to occupational or institutional setting, based on their individual benefits and risks.
