There are plenty of scientifically documented cases of vaccines backfiring — particular when people are under enormous pressure, careless, and/or shortsighted by ambition. Plenty. Polio vaccines have saved millions of lives, but there are also polio vaccines that have given people polio, and killed them. There are dengue vaccines that have created a more dangerous, more resistant strain of dengue. I certainly don't watch Tucker Carlson, so I don't know if he's using these cases as propaganda, but I've worked long enough in the global health industry to know these cases are real and terrifying. A mistake that costs 15 lives is one or two small bad decisions (possibly made by good people) away from being a mistake that costs 150,000. I'm not suggesting to anybody not to get vaccinated. I'm vaccinated and I'm glad my wife is too, for our benefit and the benefit of those we will be coming into contact with. My godmother has been hospitalized for months fighting COVID. I lost two mothers last year and I don't want a third to die. I wish to God she had gotten vaccinated in time. I'm also butting heads with a social media crackpot claiming (and refusing to offer any supporting documentation) that the Gates foundation has been kicked out of India and many African nations over their (his) vaccination policies. I think people who have opted to not get vaccinated have made a bad decision. But no, I'm not going to belittle them. I wish all our decisions were a black-and-white thing. In a nation of hot takes, we're certainly asked to believe that, but the world is a complicated place.
