Oh, another one: anti-vaccination was pushed by health insurance companies to dampen public perception of government-run healthcare.
Vaccine development and implementation fucking worked. If people were happy with the results, they might end up swayed towards publicly-funded healthcare. So... put a lid on that by whipping up a bunch of fear, uncertainty, and doubt. Some folks will no longer see the vaccination programs as successful efforts to protect public health, but as a conspiracy to... do something. And instead of pointing to it as an example of a public healthcare program, you've first got to spend time defending evidence-based medicine, which takes up so much fucking time and energy, and ultimately won't convince people who bored too deeply into that alternate-reality tunnel.
It turned a public health initiative into a fucking tar pit, and now the once-free vaccinations cost over a hundred bucks if you don't have insurance.
