BACKGROUND: Advisory committees have recommended the increased use of inactivated poliovirus vaccine (IPV) for children.
OBJECTIVES: The purpose of this study was to assess the safety and immunogenicity of three schedules using IPV administered with diphtheria and tetanus toxoids and whole cell pertussis vaccines in a dual-chambered syringe. Children also received a combination of Haemophilus influenzae type b (Hib) and hepatitis B vaccines (COMVAX).
METHODS: All infants (n = 295) received IPV and COMVAX at 2 and 4 months of age and IPV, oral poliovirus vaccine (OPV) or both vaccines at 6 months and OPV at 15 months of age.
RESULTS: After two doses of IPV 96 to 100% of infants had antibodies to poliomyelitis viruses types 1, 2 and 3, and after a third dose of vaccine (IPV or OPV) all but one child had antibodies to all three poliovirus types. After two doses of COMVAX 89 and 96% of children had protective levels of antibody to Hib and hepatitis B, respectively.
CONCLUSIONS: IPV is highly immunogenic in a two-dose schedule. Administration of a third dose of IPV or a dose of OPV at 6 months of age is highly effective. Simultaneous administration of a combination H. influenzae type b/hepatitis B vaccine did not interfere with the response to IPV.
