An all Wales database to support the appropriate vaccination of babies born to mothers with hepatitis B infection has been developed by Public Health Wales.

This report summarises uptake and timeliness of the first three doses of hepatitis B immunisation and uptake trends in babies born to hepatitis B positive mothers during 2023 who were notified to the Public Health Wales Health Protection Team. Uptake and timeliness of the dose of hepatitis B immunisation due at 12 months and serology in babies born to hepatitis B positive mothers in 2022 are also presented.

Background

Hepatitis B infection can be passed from an infected mother to her baby during birth. Babies infected in this way are very likely to become chronically infected, so can infect others. The risk of infection at birth can be reduced by over 90% by timely vaccination.

From 1st August 2017 all babies became eligible for the hexavalent (‘6 in 1’) vaccine that includes hepatitis B and replaced the ‘5 in 1’ (DTaP/IPV/Hib combined diphtheria, tetanus, pertussis, inactivated polio and Haemophilus influenzae type B vaccine) vaccine scheduled at 2, 3 and 4 months of age.

These babies should receive doses of monovalent Hepatitis B vaccine at birth and at 1 month of age, the ‘6 in 1’ vaccine as scheduled at 2, 3 and 4 months and monovalent vaccine at 12 months, a total of six doses of Hepatitis B containing vaccine. For the purpose of monitoring whether at risk babies are protected from Hepatitis B, this report focuses on uptake and timeliness of hepatitis B containing vaccine at 0, 1, 2 and 12 months.

The data presented in this report were extracted from the Public Health Wales Tarian case and incident management system on 30th December 2024, following a move from the Public Health Wales Neonatal Hepatitis B database. The database was developed to assist the Health Protection Team in the monitoring and follow up of hepatitis B immunisation of babies born to hepatitis B infected mothers and to provide a source for statistics on uptake and timeliness of hepatitis B immunisation in this group.
