Alignment-free prediction of cross-reactivity in influenza A (H3N2) anticipates antigenic drift

Author summary Influenza A (H3N2) viruses have evolved rapidly, necessitating frequent vaccine updates. Computational tools that can rapidly predict antigenic changes from sequence data alone could accelerate vaccine strain selection and reduce reliance on ti…
