re: #142 A hollow voice says NOW drain that swamp!

The vaccine acts on the part of the virus that lets it infiltrate human cells, so by changing that, the virus inactivates itself as well as the vaccine.

Or so it was explained to me…

Why assume that it cannot modify that route to evade detection and still be lethal and infective? Of course, it doesn’t do that deliberately; it just mutates— less successful mutations do not spread, more successful ones take over. Of course, it could also mutate to something less lethal, even if more infectious — indeed, the virus may “prefer” a variety that doesn’t kill the host since that leave more people available for infection.
