NCT ID NCT06501963

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at why the live attenuated influenza vaccine (LAIV), given as a nasal spray, is less effective in adults than in children. Researchers measured antibody levels in 51 healthy adults after vaccination to understand the immune response. The goal is to use these insights to design better flu vaccines for everyone.
