I think you're missing a good bit of crap that happened in your lifetime, but listing it all out isn't necessary. Except covid has been the pretty major recent one.If I do that, I have to include the first decade of my life which had a Polio epidemic. We solved that quickly by all of us being smart enough to get vaccinated. (I know the reaction some will have to this, however, please understand that I am fully aware that some can't get it, so this is not directed at those being in that unfortunate position.)
As for the second point, I think the only person who was unable to get it on this thread was me, and I got my first shot a couple of weeks ago, so you're good. But that's an entirely different story.
