Brief Summary:
This study will assess the safety, tolerability and immune response of 13-valent pneumococcal conjugate vaccine (13vPnC) compared with 23-valent Pneumococcal Polysaccharide Vaccine (23vPS). Although the study started with only 1 population, amendments to the original protocol will now reflect three participant populations. Three age cohorts will be enrolled. The first cohort (age 60-64) will be blinded. Cohort 2 (age 50-59) and cohort 3 (age 18-49) are open label. Subjects in cohorts 1 and 2 will receive 2 vaccinations 3-4 years apart. Subjects in cohort 3 will receive 1 vaccination. All participants should be naïve of 23vPS. Comparisons of immune responses from the different cohorts will be done.
