13-valent pneumococcal conjugate vaccine given with meningococcal C-tetanus toxoid conjugate and other routine pediatric vaccinations: immunogenicity and safety.

As multiple vaccines are administered concomitantly dur-ing routine pediatric immunizations, it is important to ascertain the potential interference of any new vaccine on the immune response to the concomitantly administered vaccines. In Spain, vaccination against meningococcal serogroup C is part of the routine national immunization schedule. Three different conjugate vaccines are available; this study used the meningococcal serogroup C–tetanus toxoid conjugate vaccine (MnCC-TT; NeisVac-C; Baxter Health-care, Deerfield, IL).
