Antibodies are not static.

I'm not saying that antibodies are static. It is my understanding that the antibodies have many shapes that they can use to fit themselves to germs built in to their molecular structure, but when a "mutation" occurs in the germ the antibody cannot fit to the unknown structure, only the many that it has built in to it.

no, the antibodies I don't believe have a fixed number of prordained shapes they fit to, instead they have an A and B portion, one of which is not stably encoded and so might essentially be considered a quickly mutating protein, sort of like HIV quickly mutates.

But this is a long time ago to remember, so one of us needs to take the time to look it up. If I get time, I will.
