ABSTRACT
The rapid emergence of SARS-CoV-2 variants challenges vaccination strategies. Here, we collected 201 serum samples from persons with a single infection or multiple vaccine exposures, both. We measured their neutralization titers against 15 natural and 7 engineered spike mutations analyzed antigenic diversity. Antigenic maps primary sera showed that Omicron sublineages BA.2, BA.4/BA.5, BA.2.12.1 are distinct BA.1 more similar to Beta/Gamma/Mu variants. Three mRNA COVID-19 vaccinations increased than BA.4/BA.5 BA.2.12.1. post-vaccination elicited higher all three alone, although less BA.4/BA.5. Those after two had titer magnitude recognition. Accounting for differences among when interpreting can aid the understanding complex patterns in humoral immunity informs selection future strains.
