Safety and immunogenicity of a booster dose of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine coadministered with measles-mumps-rubella-varicella vaccine in children aged 12 to 16 months.
BACKGROUND
A booster dose of pneumococcal conjugate vaccine may be administered at the same age as measles-mumps-rubella-varicella (MMRV) vaccination. This study examined the safety, reactogenicity, and immunogenicity of a booster dose of the 10-valent pneumococcal nontypeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) when coadministered with MMRV vaccine.


METHODS
In this open, controlled study, 325 healthy children aged 12 to 14 months were randomized to 1 of 3 groups: the first group (N = 110) received PHiD-CV and MMRV vaccine followed 6 to 8 weeks later by MMRV and DTPa-HBV-IPV/Hib vaccines; the second group (N = 101) received DTPa-HBV-IPV/Hib and MMRV vaccines followed 6 to 8 weeks later by PHiD-CV and MMRV vaccine; the third group (N = 114) received PHiD-CV and DTPa-HBV-IPV/Hib vaccine during 1 vaccination visit. Immune responses were assessed with GlaxoSmithKline's 22F-inhibition enzyme-linked immunosorbent assay (for PHiD-CV), commercial enzyme-linked immunosorbent assay (for MMR), or indirect immunofluorescence assay (for varicella). Adverse events were recorded by the parents/guardians.


RESULTS
After the first vaccination, 2 peaks in fever (rectal temperature > or =38 degrees C) were observed; at days 0 to 2, related to PHiD-CV and DTPa-HBV-IPV/Hib vaccination, and at days 4 to 12, related to MMRV vaccination. Booster responses to pneumococcal antigens and protein D and seroconversion rates for all MMRV vaccine components were high.


CONCLUSIONS
PHiD-CV and MMRV vaccine can be coadministered without compromising the safety and immunogenicity profiles of either vaccine.
