Study Evaluating 13-valent Pneumococcal Conjugate Vaccine In Healthy Infants

The purpose of this study will be to evaluate safety, tolerability and immunogenicity of three lots of 13-valent pneumococcal vaccine given to healthy infants. Lots will be studied for consistency of the immune response, as well as for non-inferiority and safety as compared to 7-valent Pneumococcal Conjugate Vaccine.
