Study Summary

Primary Objectives: * Assessed the immune response of the 3 SP0202 formulations, Prevnar 13 and Pneumovax 23 30 days after the administration of the single dose vaccination * Assessed the safety profile of the 3 SP0202 formulations, Prevnar 13 and Pneumovax 23

Primary Outcome

The GMs for serotype specific OPA titers were measured using MOPA which was used to evaluate the opsonophagocytic index (50% killing) of pneumococcal anti-capsular polysaccharide antibodies in human serum samples following vaccination. Titers were expressed in terms of 1/dilution.
