Combined hepatitis B vaccines.

The status and likely impact of existing and potential new combined hepatitis B vaccines were broadly considered at the Viral Hepatitis Prevention Board (VHPB) meeting in Malta, October 2001. The currently available and/or licensed combined hepatitis B vaccines in Europe and the prospects for further such vaccines were reviewed. Data on the safety, immunogenicity, and European licensing status and availability of haxavalent vaccines combining hepatitis B (HepB), Haemophilus influenza type b (Hib), diphtheria, tetanus, and pertussis (acellular) (DTPa), and inactivated poliovirus (IPV) antigens were presented. Finally, the impact of the availability of combined hepatitis B vaccines on hepatitis B immunisation programmes in Europe were examined and the added value of combined hepatitis B vaccines globally was estimated.
