NCT ID NCT01692886
First seen Jun 02, 2026 · Last updated Jun 23, 2026 · Updated 1 time
Summary
This phase 3 trial tested a new 13-valent pneumococcal vaccine (13vPnC) in over 1,600 healthy infants in China. The vaccine was compared to an existing 7-valent version to see if it triggers a stronger immune response against 13 types of pneumococcal bacteria. Researchers also monitored safety, including any side effects like fever or injection-site reactions. The goal is to offer broader protection against serious infections like pneumonia and meningitis.
