the vaxx isn't going to kill you. the mass die off is an antivaxxer revenge fantasy. there are no known drugs where you take one to three doses, are completely asymptomatic for years, and then drop dead. if the antivaxxers had any real data other then garbage posted in obscure predatory journals or post from "theethicalskeptic" they would have posted it by now. you're going to be fine.
