The CDC voted to remove the universal newborn dose of the hepatitis B vaccine following an advisory-panel recommendation, after earlier guidance allowed parents and health care providers to decide whether infants born to hepatitis B–negative mothers should get the birth dose.Under the new schedule, infants of mothers who test positive for hepatitis B or who are at high risk will still receive the birth dose, officials said, while critics warned the change could increase missed opportunities for preventing perinatal transmission and supporters said it reflects current disease patterns.
