Fish also pointed to the interferon response, or proteins that help the body mount an early and innate immune response to clear a virus. If, as with Omicron, the spike protein significantly mutates to the point where it becomes almost unrecognisable to the immune system, both antibody and T cell responses are likely to be weakened. But finding immune people is an increasingly tricky task. Genetics can enable us to dichotomize the population into whos more likely [to develop a severe case of COVID-19] and whos not, says Beckmann at ISMMS.
