Abstract
By November 2021, after the third wave of severe acute
respiratory syndrome coronavirus 2 infections in South Africa, seroprevalence was 60% in a rural community and
70% in an urban community. High seroprevalence before
the Omicron variant emerged may have contributed to reduced illness severity observed in the fourth wave.
