What happened in the past?
Jesse Bloom is based at the Fred Hutchinson Cancer Research Center in Seattle, Washington. He saw these four seasonal coronaviruses as a possibility to better understand how Covid-19 might evolve in the future. However, regardless of how much scientists have searched for answers, we still don’t have that many.
He studied a seasonal coronavirus which is called 229E. This virus infected people many times during their lives, but we have no idea if these reinfections are the result of a weaker immune system and immune response in their human hosts, or if there is the possibility that this virus suffers some mutations which help it dodge immunity.
