In trying to understand this, we need to understand some important things about the biology of coronaviruses and their interaction with their hosts: us. Sars-CoV-2, the virus that causes Covid, is not going away. Like other coronaviruses, it will likely infect

Why we shouldn’t worry about Covid super strains

But while I would say that this is not impossible and could happen, it would be very unusual if this took place. We know from previous epidemics what happens when a population encounters a new virus.
