I live in an actually authoritarian country. Only the most privileged people here don't get vaccinated, and among them it's a very small group, and mostly foreigners. No one is forced to, and no one is being forced to do anything else with their body.
I find this jump to tyranny argument disgusting. How on Earth would that work? In a country where one man can order the military to kill its own citizens there is no logical connection between vaccinations and smoking or obesity.
Americans (and a lot of other nationalities in the West, but mostly Americans) need to gain some perspective on the difference between tyranny and responsibility. I got vaccinated (with a Chinese vaccine, the horror!) because I consider it my duty to my family, my adopted country, and the world.
And guess what? Vaccination has been stupendously effective and our country is almost back to normal. And still the government is not locking up smokers or fat people.
