The effects of hepatitis B vaccination on infants born to carriers without HBe antigenemia
Insights
Hepatitis B vaccination alone may protect infants born to hepatitis B e antigen-negative mothers. Infants receiving only the Hepatitis B vaccine showed no seroconversion, unlike unvaccinated infants.
Area of Science:
- Hepatology
- Immunology
- Pediatrics
Background:
- Hepatitis B virus (HBV) infection poses a significant risk to infants born to HBsAg-positive mothers.
- Hepatitis B e antigen (HBeAg) status of the mother is a key factor in vertical transmission risk.
Purpose of the Study:
- To evaluate the efficacy of Hepatitis B (HB) vaccination alone in preventing HBV infection in infants born to HBeAg-negative mothers.
- To assess the role of HB immune globulin (HBIG) in conjunction with vaccination.
Main Methods:
- Retrospective study of 53 infants born to HBsAg-positive mothers.
- Analysis of HBV seroconversion rates in 17 infants born to HBeAg-negative mothers based on vaccination status (HB vaccine alone vs. no vaccination).
- Correlation analysis with HBIG administration.
Main Results:
- None of the 6 infants receiving only HB vaccination showed seroconversion.
- 6 out of 11 (54.5%) infants who did not receive HB vaccination showed seroconversion.
- No significant correlation found between seroconversion and HBIG administration.
Conclusions:
- Hepatitis B vaccination alone appears sufficient to prevent HBV infection in infants born to HBeAg-negative mothers.
- HBIG may not be essential in this specific patient group.
- Further prospective studies are warranted to confirm these findings.
Abstract:
A retrospective study on fifty-three patients born to hepatitis B surface antigen (HBs antigen) positive mothers was carried out. Among 17 patients born to hepatitis B e antigen (HBe antigen) negative mothers, six patients received hepatitis B(HB) vaccination and eleven did not. None of the six patients who had received HB vaccination showed seroconversion, while six of the 11 patients (54.5%) without HB vaccination did show seroconversion. There was no definite correlation between the frequency of seroconversion and the administration of HB immune globulin (HBIG). HB vaccination alone may be sufficient to protect infants born to HBe antigen negative mothers from HB viral infection.
