Summary

This study tested whether a higher-dose flu shot creates a stronger immune response than the standard-dose shot in adults aged 50 to 64. About 1,180 participants received either the high-dose or standard vaccine. Researchers then measured antibody levels and tracked side effects to compare safety and effectiveness.
