The CDC’s Advisory Committee on Immunization Practices (ACIP), reconstituted by Health Secretary Robert F. Kennedy Jr., voted to recommend that individuals 6 months and older should consult healthcare providers before receiving COVID-19 vaccines. The panel also voted to remove the recommendation for the combined MMRV vaccine in young children and postponed a vote on delaying the birth dose of the hepatitis B vaccine. These changes risk undermining longstanding federal immunization policies and could impact insurance coverage and public health protection. The decisions have raised concern among public health experts regarding vaccine safety and effectiveness assessment.
