- Demonstrate 13vPnC without AlPO4 is as immunogenic as 13vPnC with AlPO4 to select a 13vPnC formulation.
- Demonstrate that the selected 13vPnC formulation is as immunogenic as 23vPS (by IgG).
- Safety and tolerability of the selected 13vPnC formulation given 12 months after a previous dose of the selected 13vPnC.
