A vaccine is just a dumbed down version of the virus, so getting one is just like catching the virus just with little to no symptoms. (Unless you have a bad immune system.)
Actually we remember it because a bunch of stupid people died defending a cannon that wasn’t theirs to demonstrate that they were independent from a land that rightfully owned that place. But mexico was sort of not exactly all that good back then, so those folks weren’t wrong, they were just stupid.
There isn’t room.
