We have posted data providing real-time measurement of human neutralizing antibody landscape to seasonal influenza. Data explain spread of subclades K (H3N2) & D.3.1.1 (H1N1), identify subclade K subvariants w reduced neutralization, & can inform choice of strains for next vaccine.

Our preprint examining the specificity of human antibodies that cross-react with subclade K H3N2 viruses was posted this morning on medRxiv. These studies have implications on what vaccine strains should be selected for next year’s influenza season. 1/ www.medrxiv.org/content/10.6...
