Write the reason behind why the BA.5 omicron sub variant of COVID-19 is more likely to reinfect people. Why is the BA.5 omicron subvariant of COVID-19 more likely to reinfect people?
Further explanation: The BA.5 subvariant appears to evade the immune system. That is, people with prior infection or vaccination are still at risk for BA.5. Certain mutations in the BA.5 subvariant appear to help it escape immunity from both vaccination and prior infection. I have attached an article from the New England Journal of Medicine to help you get started.
