Then fallibility of the government is not what you are questioning here. You are questioning the fallibility of every biologist and pathologist in the world cross-checked against one another.
You've mistaken. I'm not arguing against choosing to take vaccines, or their efficiency. All I'm arguing against is the push I'm starting to see in recent years toward making them mandatory and making this enforceable by the government.
That doesn't fit your arguments up until this point. Skepticism of vaccines themselves bereft of scientific support is nothing more than casting undue ignorance on a safe and vital process of our society.
As for allowing the government to enforce it, the only reason it remains semi-mandatory instead of outright mandatory is the numbers of those refusing vaccination. Had people not cooperated with the smallpox vaccination campaign, they would have been forced, and rightfully so (see: social contract). But they did not, because they saw the horrors of disease first hand.
Vaccination refusal rates also went down after the MMR epidemic, because people were exposed to disease again. Conclusion: Everybody not a fanatic believes vaccines and assorted risks are better than disease epidemics when forced to genuinely choose between them. Derealization causes refusal.
Well, if you kill herd immunity that choice will return, and not slowly either. Instead of oscillating back and forth between generations of diseased children and healthy ones, we should obviously choose to enforce now. This is a legitimate interest of both the people collectively and the people individually.
And I'll tell you one other thing: The only "right to refuse" is because it doesn't get all that bad on the large scale most of the time, even though it continues to chip away at individual lives. If you came into a hospital and got diagnosed with early-stage rabies, you can be damn sure you wouldn't be allowed to refuse the vaccine.
If people are vulnerable enough to liars and hucksters that they can't choose to not get children sick or killed when they don't personally witness it, then giving the government the right to force them is an unambiguous good for all humanity.
