The FDA has approved updated COVID-19 vaccines, including mRNA shots from Pfizer and BioNTech, but with new restrictions on who can receive them. The approvals focus on high-risk individuals, such as those aged 65 and older and those with underlying health conditions, limiting access for some children and adults. This move comes as COVID-19 cases rise in the U.S. and reflects ongoing concerns about vaccine distribution and eligibility. The agency has also rescinded emergency use authorizations for certain vaccines, marking a shift in its approach to managing COVID vaccine approvals.
