Does it really matter? All viruses mutate when they are stopped in some

But some like smallpox hardly mutate at all.

Although recent research into pox viruses show that they adapt in other
ways that have a similar effect when overcoming the body's defences.

Doesn't explain why we managed to wipe out smallpox in the wild.
