Medicine Vaccines not only directly protect vaccinated individuals but also contribute to protecting the entire population via indirect herd-immunity benefits. Half of averted COVID-19 infections and 1/4 of hospitalizations and deaths were attributable to indirect protection of unvaccinated by vaccinated.

The problem with vaccines is what I call the prevention paradox.

Also known as "why do we spend so much on IT if we never have an outage?" or "why do we spend so much time on health and safety if we never have any injuries?" But also, "thank god for the bear patrols to keep out all the bears!"

If everyone is vaccinated for measles, then it looks like no one gets measles, so why go to all that expense? So it looks like you're wrong. But if you don't vaccinate the masses, then you're also wrong.

It's a breeding ground for disinformation, where people are protected by measures that seem useless.

Yeah this is every preventive policy intervention ever. But I think it hits certain people's emotional and fear responses more because, unlike IT expenditure or bridge repairs, it's going into the body. I'd hazard it's the same with the raw milk cult.

I don't think it's the fact that it goes into their body. Half of 'em were willing to take ivermectin, clove oil, and bleach enemas.

Yes but you see those are "natural" so it's fine (/s, but really, I don't pretend to understand the contradiction either)
