Immunogenicity and safety of an inactivated hepatitis a vaccine administered concomitantly with a pneumococcal conjugate vaccine in healthy children 15 months of age.

The immunogenicity and safety of hepatitis A vaccine and pneumococcal conjugate vaccine, administered separately or concomitantly in children 15 months of age, were evaluated. After completed vaccinations, antihepatitis A and antipneumococcal geometric mean concentrations were similar across groups. Both vaccines were well-tolerated when given concomitantly during the second year of life.
