#Covid #BA.3.2

Original antigenic sin for the win:

Niu et al. show in a preprint that lack of ancestral SARS-CoV-2 imprinting promotes BA.3.2.2 infection in children, while pre-Omicron mRNA vaccination prevents.

The risk being future escape from Class I ABs, like with the 455-456 "FLip" mutations.
