title: Long-term immunogenicity of two pediatric doses of combined hepatitis A and B or monovalent hepatitis B vaccine in 8 to 10-year-old children and the effect of a challenge dose given seven years later.
abstract: A total of 465 children aged 8 to 10 years were vaccinated with 2 doses of Recombivax-HB 2.5 microg (RB) or Twinrix-Junior 10 microg/360 EL.U (TX), according to a 0 and 6 months schedule. Seven years postsecond dose, a challenge dose of vaccine was given. All vaccinees in the TX and 98% in the RB group showed an anamnestic response. Vaccination at the age of 8 to 10 years with two-pediatric doses of TX or RB given with a 6 months interval induces a long-lasting immunity in most vaccinees.
