It’s about the right to expose others to a risk without their consent.
You don’t have the right to expose others to a deadly disease. If you undergo the “medical procedure” (an injection, not surgery, brain transplant or anything complicated, expensive or risky) you reduce risks for you and others, as well as you avoid the risk of using my taxes to pay for additional medical care you wouldn’t need if you just had the very minor inconvenience of two injections.
Put another way, you have so little faith in the efficacy of the vaccine's ability to protect you from the effects of covid that you want others to take that same vaccine just so that you can feel a little better about your odds. And the other side is the selfish one. That sum it up?
Yeah but I'm not responsible for that deadly disease, and I don't control it. It's everywhere all the time. And it's really unclear if me getting vaccinated actually helps anything. It's a completely different thing if you are in 100% control of where a factory should be placed. The equivalent would be to argue that the factory should be banned because someone somewhere are in fact misusing these explosives for evil purposes, and therefor it should be closed forever.
With that reasoning, you are always exposing others to some indirect risk by any activity you do, everything must be banned. There's a certain limit to what is considered within your direct control and can be considered your personal responsibility.
You are expected to allow yourself to be subjected to whatever injections and suffer whatever loss of human dignity for the purpose of some vague "risk-reduction" that ultimately will contribute little towards the actual goal which is never clearly defined and is subject to eternal revision (only in good faith though :)). You are expected to do this to your children as well.
