‘Super-immunity’ might not be so super after all. New research1 suggests that protection against the SARS-CoV-2 virus slides over time even in people who have experienced both SARS-CoV-2 infection and had vaccines against it, a combination that initially provides hyper-charged immunity. The research, which has not yet been peer reviewed, was conducted before the Omicron variant emerged. But it sharpens questions about how well ‘super-immunity’ — also known as hybrid immunity — will fare against the latest iteration of the coronavirus.
