Administer the first dose of hepatitis B vaccine within 24 hours after birth
The 1st dose of hepatitis B vaccine has to be given within 24 hours after the child is born. Among people infected in infancy or early childhood, about 95% go on to chronic hepatitis. People infected only after they are grown mostly get better on their own, so this dose is more useful the earlier it is given. If the mother's hepatitis B surface antigen is positive, the child also needs hepatitis B immune globulin within 12 hours of birth, at the same time.

No cost at all. The hepatitis B vaccine is part of the routine immunization program, so it is provided free of charge. It is given to newborns in the hospital on the day of birth; no extra trips are needed.
The World Health Organization says: "All infants should receive the hepatitis B vaccine as soon as possible after birth (within 24 hours)." The reason is that "about 95% of infections in infancy and early childhood develop into chronic hepatitis." The great majority of people infected as adults clear it on their own (they get better without treatment). The WHO's own words are that "under 5%" of infections after adulthood become chronic. The National Health Commission (国家卫生健康委员会) protocol for interrupting mother-to-child transmission requires that a child born to a mother who is positive for hepatitis B surface antigen "receive the 1st dose of hepatitis B vaccine as early as possible within 12 hours after birth, and at the same time an injection of 100 international units of hepatitis B immune globulin."
