Overview
- The FDA will now require randomized, placebo-controlled trials for COVID-19 booster approvals in healthy individuals aged 6 months to 64 years, marking a shift from prior immunobridging-based approvals.
- Annual boosters will remain available for adults aged 65 and older and individuals with underlying health conditions, with estimates suggesting 100–200 million Americans will still qualify.
- The policy aligns U.S. vaccination guidance with European nations, moving away from broad recommendations to a more targeted, risk-based approach.
- FDA officials Marty Makary and Vinay Prasad emphasized the need for robust clinical evidence to rebuild public trust and address declining booster uptake, which has fallen below 25% in recent years.
- The new framework could deter vaccine manufacturers due to the high costs and logistical challenges of conducting large-scale trials for low-risk populations.
