Food, water, and air regulations are completely different. To be analogous, they would have to be regulations about food and drinks you must consume, or gasses that you must breathe in. Even if that were the case, it would still be less invasive than an injection with RNA, which enters your cells, which causes your cell to produce spike protein, which causes your immune system to attack those cells. Note again: I personally did take the vaccines, the point is that this is not comparable to food regulations. When I did take the vaccine I already knew that medically there was no necessity: due to my age and no comorbidities the risk of complications from COVID was known to be extremely low, and I knew that it wouldn't help other people either because it would not get R<1, but I simply made the decision because I did not want to lose my sense of smell for a couple of months. I was under no illusion that I was saving the world with that decision. If one was under such illusion, I can certainly understand the frustration with other people not saving the world. But this is not reality.

Your point about schools mandating vaccines is good.
I'm not categorically against vaccine mandates. For a sufficiently transmissible disease, which is also deadly, and where spread can be stopped by vaccination, it can be justified. Measles may be a candidate: very transmissible (more so than COVID) and deadly for children (2.6 million deaths in 1980), and a vaccine which is extremely effective (99% immunity against infection) and has a long term safety record (complications <1 per million). COVID is not such a disease, and the COVID vaccines are not such vaccines.

Even so, in my country it is not compulsory to get vaccinated against the measles, not even in schools. Certainly one does not have to show a measles vaccination proof when entering a non-essential business like a restaurant, which one does have to show for COVID. Nor does one have to get a booster every 9 months, which one does, by law, for COVID.

> I’m talking out of frustration that I’ve made lifestyle changes to help others who clearly don’t feel the need to reciprocate.

Ok but this is not a good reason to compel other people to vaccinate. These people likely did not ask you to make the changes that you did. Nor are the changes that you made likely to have made much difference in the lives of these people, and whether or not these people do get vaccinated has a very minimal impact on your life, other than your frustration.

The fact that you feel like it would be a nice gesture from them if they "reciprocated" by getting vaccinated does not weigh against the negatives. Many of these people are probably genuinely afraid to take the vaccine. They may be very misinformed, but the fear is real. If you put sufficient pressure on these people via the government, for instance by threatening to take away their job and their ability to provide for their children, then they may well take the vaccine. But these people may resent those who forced them into it for the rest of their lives, and feel alienated from a society that made them do it. And some of them will feel ill for a day or two (as many do after getting the vaccine), which may cause them to think that any future pain or health problems were caused by the vaccine. It this worth it to you in order to act out your frustration that they "don't feel the need to reciprocate"?
