NCT ID NCT01692886
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 3 trial tested a 13-valent pneumococcal vaccine (13vPnC) against the older 7-valent version in over 1,600 healthy infants in China. The goal was to see if the newer vaccine triggers a stronger immune response and is just as safe. Infants received four doses starting at 3 months old, and researchers measured antibody levels and side effects.
