The FDA is significantly altering its Covid vaccine rollout. New vaccines will require placebo-controlled trials, impacting future approvals but exempting those for high-risk groups this fall. Annual shots for healthy adults and children are unlikely, moving away from the yearly flu shot model. This decision, influenced by FDA officials and potentially Robert F. Kennedy Jr.'s mandate, aims to improve evidence-based vaccine strategies, though concerns remain about access and patient choice. The shift may delay fall vaccine availability for some.
