American children born in 1998 are required by most states to be injected with 33 or 34 doses of 9 or 10 different viral and bacterial vaccines to enter school, including three doses of hepatitis B vaccine.
In 1991 the Advisory Committee on Immunization Practices (ACIP) of the Centers for Disease Control (CDC) recommended that all infants be injected with the first dose of hepatitis B vaccine at birth before being discharged from the hospital newborn nursery.
>>>Are most children born in the USA given hepatitis B vaccine?
No. Only when the mother is HBsAg positive are the new borns vaccinated.
