NCT ID NCT04498832
Summary
This study tested if a high-dose flu shot given as a muscle injection works better than a standard-dose shot given under the skin for people aged 60 and older in Japan. It involved 2,100 healthy volunteers and measured their immune response and safety 28 days after vaccination. The goal was to see if the stronger shot provided better protection against four common flu strains.
