Title

Long Term Follow-up of a Study to Assess the Safety and Immunogenicity of a Hepatitis A Vaccine Administered With and in the Absence of DTPaHibIPV, OPV and MMR Vaccines
A Phase III Randomised, Open, Controlled Study to Assess the Safety and Immunogenicity of Concomitant Administration of Virosomal Hepatitis A Vaccine (Epaxal®) With DTPaHibIPV, OPV and MMR Vaccines vs. Non-concomitant Administration in 12-15 Month Old Children. Follow-up: Serological Long-term Follow-up of Subjects for up to 42 Months, 5.5 and 7.5 Years After the Second Dose.

The primary purpose of this study was to assess whether the protection afforded by Epaxal vaccine co-administered with diphtheria, tetanus, Bordetella pertussis, Haemophilus influenzae type b, and inactivated polio vaccine(DTPaHibIPV), oral polio vaccine (OPV) and (measles mumps and rubella) MMR vaccines against hepatitis A was not inferior to the protection afforded by Epaxal administered alone. The aim of the follow-up phase is to obtain information on the long term protection afforded by Epaxal, and to compare this with an alternative hepatitis A vaccine (Havrix).

Group A Experimental

Epaxal + concomitant administration of DTPaHibIPV, MMR, OPV

Group B Experimental

Epaxal, with administration of DTPaHibIPV, MMR, OPV one month later

Group C Active Comparator

Havrix 720 + concomitant administration of DTPaHibIPV, MMR
