Avian Influenza research hub

Phase IV multicenter immunogenicity and safety study of the Seqirus licensed zoonotic influenza vaccine (H5N8) in adults immunized with an H5N1/MF59 influenza vaccine, approximately 20 years before the trial, compared to H5 naive adult participants.

This study is looking at a new bird flu vaccine (H5N8) in adults. We want to see how well it helps your body fight off the virus, especially if you had a similar bird flu vaccine (H5N1) many years ago, compared to those who haven't had a bird flu vaccine before.
