Summary

This study tested a single combination shot that aims to protect against both COVID-19 and the flu at the same time. About 980 adults aged 50 and older received either the combo vaccine, a flu shot alone, a COVID-19 shot alone, or both shots separately. Researchers checked for side effects and measured immune responses over 12 months to see if the combo is safe and works well.
