Prevention of Hepatitis B by immunization of the Newborn Infant a Long-term Follow-up Study in Stockholm, Sweden
1995

Among 25 children to such mothers, 1 HBsAg carrier and 5 children with asymptomatic seroconversion were found. To newborns of HBeAg-negative/anti-HBe-negative mothers, only vaccine was given. Among 15 such children, no HBsAg carrier (but 1 child with an asymptomatic seroconversion) was found. In babies of HBeAg-negative/anti-HBe-positive mothers, immunization was withheld between 1983 and 1987. Among 90 such children, 1 HBsAg carrier and 8 asymptomatic seroconversions were detected. After 1987, newborns in this group were vaccinated whereafter 3 asymptomatic seroconversions were found among 82 children.
