I trust old style vaccines, where they give you a weakened version of whatever the bug is, but not the new rDNA type that tweak the building blocks of the bug, then need booster after booster after booster.
I got all kinds of vaccines while in the Army, the one I remember most was the typhoid shot, the shot itself didnt hurt, but about half hour later my arm felt like someone had been punching me over and over until my muscles were pulp, and that lasted a few weeks. If that was the vax there's no way I'd want the actual bug.
