VirPLM: Antigenic prediction of influenza A/H3N2 viruses with a fine-tuned protein language model.
MOTIVATION Human influenza A/H3N2 viruses undergo rapid antigenic evolution primarily driven by the hemagglutinin subunit 1 (HA1). Within HA1, amino acid substitutions under immune pressure cause antigenic drift, necessitating frequent updates to vaccine strains. While hemagglutination inhibition (HI) assays remain the...
