Consensus H3N2 HA immunogens incorporating key antigenic mutations elicit broad-spectrum neutralising responses

Seasonal influenza A/H3N2 poses a significant public health burden due to its rapid antigenic evolution, necessitating frequent vaccine updates. This study systematically analysed the antigenic evolution of 14 H3N2 vaccine strains (2000-2022) using pseudovirus-based neutralisatio...
