The COVID-19 pandemic has been characterized by a continual series of variants, with each new variant displacing the previous one. For example, in the first half of 2022 in the U.S., we saw the Omicron BA.1.1 variant be displaced by BA.2, which was then displaced by BA.2.12.1, which in turn was displaced by BA.4/BA.5, with BA.5 becoming dominant in July.
