'Immune imprinting' by different SARS-CoV-2 spike sequences from variants, vaccines means we now have diverse patterns
New research shows that the first SARS-CoV-2 spike protein a person encounters, be it by vaccination or infection, shapes their subsequent immune response against current and future variants. That is, it imparts different ...
