Post-vaccination serological test results of infants at risk of perinatal transmission of hepatitis B using an intensified follow-up programme in a London centre.

Immunisation of infants born to hepatitis B virus (HBV) infected mothers is an important public health measure to prevent mother-to-child transmission of HBV. Post-vaccination serological tests (PVST) inform the success of the infant HBV immunisation programme and identify infected infants. Previous studies suggested that the rates of PVST in the UK programme were unsatisfactory.
