I use to think anti-vaxxers where a bit nuts but now... Actually I don't, not entirely.
If you can prove you make antibodies against it, and it can't be recontracted, there is no need for a vaccine for you. And yet they might try to force it on us anyways? Not me if I show antibodies. (I hate needles)
I'm not saying it's proof but we have seen a case of stopping vaccinations and seeing an immediate drop in autism in kids. (there's no plausible explanation, might be as simple as no diagnosing)
Also I'm actually opposed to measles vaccines. It's a goal of mine to contract it if possible from an anti-vaxxer (even though I had the vaccine, I'm seriously hoping I still can). Why? Because it trigger epgienetics that make you way less likely to have a heart attack. People before 1957 are considered immune so we somehow lost that benefit epigenetically speaking and the only way to resurge it is to have measles. And if you think about the symptoms it makes sense that it affects the epigenetics of the cardio system.
Polio is always said to be a thing of the past just due to vaccines. But prenatal vitamins are just as effective (and generally speaking way better for the humans). Unknown fact, only a very small percentage of people with polio have any lasting symptoms (the ones we fear), and it has been shown those that do basically exclusively have nutritional deficiencies. I'm not against the vaccine, or for it, kinda depends on what country you are in.
