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.

Description
Inclusion Criteria:
Original study:
- Written informed consent obtained from the parent/legal guardian of the subject.
- Free of obvious health problems as established by medical history and/or clinical examination before entering the study.
- At least 8 kg of body weight at age of 12 months.
Follow-up phase:
- Subjects enrolled and randomised in the original study and having received two doses of the hepatitis A study vaccines.
Exclusion Criteria:
Original study:
- Children not having received 3 documented doses of DTPaHib and polio vaccines during infancy
- Children having received a documented dose of MMR during infancy
- Use of any investigational or non-registered drug or vaccine within 30 days preceding the first dose of study vaccine, or planned use during the study period and the 30 days safety follow-up after the last dose.
- Chronic administration (defined as more than 14 days) of immunosuppressants or other immune-modifying drugs within six months prior to the first vaccine dose.
- Administration of systemic corticosteroids (inhaled and topical steroids are allowed).
- Administration of a vaccine not foreseen by the study protocol within 4 weeks prior to the first dose of study vaccine.
- Previous vaccination against hepatitis A.
- Any confirmed or suspected immunosuppressive or immunodeficient condition, including human immunodeficiency virus (HIV) infection.
- History of allergic disease or reactions likely to be exacerbated by any component of the vaccine.
- Major congenital defects or serious chronic illness
- Acute disease at the time of enrolment.
Follow-up phase:
- Children who had received a hepatitis A antigen containing vaccine since the last visit
