Summary
The primary objectives of this study are to evaluate the safety and tolerability of the pneumococcal 21 valent conjugate vaccine (V116), and to evaluate the serotype-specific opsonophagocytic activity (OPA) post-vaccination with V116 and PCV15 (a pneumococcal conjugate vaccine that includes 15 serotypes) + PPSV23 (comprised of the polysaccharides from 23 of the serotypes causing disease in adults) post-vaccination within each vaccination group separately.
