This is no truer than the quote about "each deadliner than the other". In fact many virii mutate continuously, c.f. the flu shot you need to get every year because there are always new strains.
It seems currently that SARS-CoV-2 is not doing this. But the science is still new and we just don't know.
- goalieca 7y agoWe are observing mutations, and there’s a number of preprints out there describing mutations along the spike protein. I’m not sure which of the 100 vaccine candidates would continue to work if that were the case, but perhaps it will become like the flu where we need a different vaccine per strain and that sometimes the vaccine only provides partial protection
- watwut 7y agoCovid-19 is mutating and they are using mutations to track how it spreads. That is why they think that US strain cme from Europe. However, it is mutating slowly.
