This is why I don't buy the flu shot argument that a

and key means it has to be specific.

No. A virus has hundreds of antigens on it's surface. You have
to produce antibodies to a number of them, not all of them (which
would be impossible, as they are constantly shifting).
I think you got the scale of things mixed up.... think of a
virus as a building, hundreds of locks, some of which lead to the
places you can place explosives to implode it. Like 9/11.
The more keys, the greater your chances of getting in.
Vaccines generate new keys, most useless, but some work. The more keys
the better.
