First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a new seasonal flu vaccine made from animal cells instead of eggs in over 3,200 adults aged 50 and older. Participants received either the new vaccine or a standard egg-based flu shot, and researchers measured their immune response and side effects. The goal was to see if the cell-based vaccine works as well as the standard vaccine in protecting against the flu.
