Though seemingly reasonable, the sarcastic 9mm vaccine progressing to .45 and ultimately to nukular immunity analogy is terminally flawed. And cute in a condescending sort of way.

In actual fact, immunity against one virus does (but not always) precipitate an immunity to another virus of the same class.

Of course, taking a 9mm once does not protect against taking a 9mm again, let alone taking a .45. Progressing all the way to eventually acquiring nukular immunity is like saying strong viral immunity will provide protection against bacteria.

Comparing a .45 to a coronavirus is like comparing a bumper sticker to War and Peace, even facetiously just to make a point. Effective and if it works for you, spread the word!
