Summary

This large Phase 3 trial tested a new quadrivalent flu vaccine in over 2,700 healthy children aged 6 to 35 months. The study compared two doses of the experimental vaccine against a standard flu vaccine to see how well it triggers an immune response and whether it is safe. Researchers monitored side effects and collected blood samples to measure antibody levels. The trial is now complete, and results will show if this vaccine is a good option for protecting young children from the flu.
