>>13613336>There will always be mutations but you can engineer the first version to have zero lethality. Viruses tend to mutate into less lethal versions.Sure
But at what point will the zero-lethality virus be too different from wild-type sarscov?
The point is a zero-lethality covid virus, where the virus has the ability to replicate and spread.
So 0-lethality, high infectivity, high replication.
Then the virus is always going to get into cells via the spike protein. Those cells will always include the tissue which we dont want attacked by the immune system. So this virus will always produce a harmful, lethal response.
>but mutation to less lethalitySure, but it would do this by mutating the spike protein, so that it doesnt enter cells we want to keep safe.
And if the spike protein is mutated, then it wont be an effective way of inducing immunity against wild-type covid virus
