The panel, formally known as the Advisory Committee on Immunization Practices — whose members Health Secretary Robert F. Kennedy Jr. fired in June and replaced with a group that has largely expressed skepticism of vaccines — recommended that women who test negative for hepatitis B can decide in consultation with a health care provider whether their baby should get the birth dose. The group suggested waiting until at least 2 months of age for the first dose if the vaccine is not given at birth.

中國曾有總人口近10%乙肝病毒攜帶者，90年代在獲得美國的乙肝疫苗後，對新生兒注射免疫，乙肝病毒攜帶者在年輕人中幾乎絕跡。
