The U.S. Advisory Committee on Immunization Practices voted to end the policy requiring all newborns to receive the hepatitis B vaccine at birth.This change, supported by Acting CDC Director Jim O’Neill, now recommends vaccinating only babies born to mothers who test positive or have unknown hepatitis B status, while parents and doctors will decide for others.Critics like Senator Bill Cassidy warn that delaying vaccination could increase hepatitis B infections and undermine decades of progress in controlling the disease.
