We're at this weird point as a society, where I can't tell when somebody is trolling, and when people are legitimately stupid.
Vaccines obviously, clearly, observably, demonstrably work. There's no smoke, no magic, and no conspiracy. When you vaccinate a population, diseases that are vaccinated drop off sharply in that population. That's it. You can research this in five minutes, and not infrequently, you can observe this cause and effect live as world governments vaccinate the populations of undeveloped countries.
Where it all goes off the rails, is when some vacuous scrotum gets scared of their own shadow, and makes some dubious, unsubstantiated claim about vaccines. "Oh, they cause autism." "That's how the government controls you." "The doctors just want your money." "If you take the Westerners' vaccine, it will make you stop believing in God." Those are all real things that came out of real people's real mouths. Not one has a scrap of evidence behind it, and they've all been disproven a hundred times over.
Maybe the CDC will get together and rebrand vaccines as "NASCAR enjoyment serum" or something similar, to make it more palatable to the knuckle-dragging mouthbreathers that are literally killing people with their ignorance.
