Ten-year follow-up study of neonatal hepatitis B immunization: are booster injections indicated?

One hundred and fourteen children, born to HBsAg-positive mothers received in the first year of life passive active prophylaxis for hepatitis B virus (HBV). They have been followed up to 10 years. A booster dose given in a cohort at the 5th year does not seem to increase protection against HBV. No difference in immunological memory was present at the 10th year between the group of children who had received the booster dose at 5 years of age and the group who did not.

Different degree of antibody response to hepatitis B virus vaccine in breast- and formula-fed infants born to HBsAg-positive mothers.

Antibody response to hepatitis B virus vaccine was compared in 47 breast- and 112 formula-fed infants born to hepatitis B surface antigen-(HBsAg-) positive mothers. No difference was observed as to the percentage of infants who seroconverted. However, formula-fed infants developed transient but significantly higher anti-HBs antibody levels as compared to breast-fed infants. Suppressive factors in human milk or orally induced tolerance may explain this finding. The latter hypothesis may be supported by the presence of HBsAg in more than half of the milk samples we studied.
