Full disclosure: I have not gotten a COVID vaccine; I am quite unlikely to get a COVID vaccine. If you want to get a COVID vaccine, please feel free to do so, though I would urge informed consent.
Good vaccines are difficult to make, but there's no doubt that a well-tested and approved vaccine saves lives. We don't have polio or smallpox today, thanks to vaccines.
I made the decision not to get the COVID vaccine. I have had COVID twice, confirmed with positive testing. I self-quarantined both times. I was quite tired and slept a lot during both infections. I am definitely on the list of those with co-morbidities. I don't have "long COVID", but my partner definitely does. I don't discount COVID, it's a serious flu, and various flu infections kill a lot of people every year.

In the early 90's, in the run-up to the first Gulf war, military personnel were widely asked to volunteer for an experimental vaccine. We were told this was an anti-anthrax vaccine, necessary because it was believed (or so we were told) that Saddam Hussein had stockpiles of anthrax-based biological weaponry. Those who were deployed weren't given the option, but those who did not deploy were asked to volunteer.
I did not volunteer. Some weeks after the call for volunteers went out, my Navy section non-commissioned officer (LPO) told me that I was required to volunteer. I disagreed, saying that was an order not voluntary. I was then told that I was ordered to volunteer, and that I'd be court-martialed if I did not volunteer. Now this is shitty, but when you sign up for the military, you sign up for stuff like this whether you like it or not. I don't know if I could have successfully fought this, but it seemed like a bad idea, so I agreed that I would "volunteer". I was then ordered to sign a paper stating that I had "volunteered" for the shot of my own free will. I refused this initially, but I got called out again by my leadership and threatened with court-martial if I refused an order to sign the paper. I was a scared 19-year-old, and didn't know if I had legal grounds or not, so in the end, I agreed to sign.
I wish I had never signed that paper. I wish I'd had the courage to tell my leadership to take me to court-martial. After I got the shot, I got sick. Constantly. I got sick again and again, taking weeks to get better between each bout. Fever, chills, headache, it was like a flu that went on for months. It was so bad at one point that my chief petty officer sent me to bed for a week, even when Navy medical refused me any treatment beyond Ibuprofen. This condition affected me on-and-off for well over a year.
Many years later, I read about "Gulf War Syndrome." I read of government claims of exposure to chemical agents while deployed - except that I never deployed to Iraq, and neither did thousands of others with symptoms. I truly believe that Gulf War Syndrome was caused by a chemical agent our own government deployed, in the form of a vaccine that I "volunteered" for, and thus have no recourse against my own government.
When I see my own government telling me that I "have" to get another experimental vaccine, a vaccine that cannot prevent transmission or infection from COVID, a vaccine that no one can be held liable for problems, and that same government threatening me with loss of public access, threatening me with "vaccine passes", pushing companies to exclude me from the job market unless I comply, I have this to say:
GO F** YOURSELVES
I won't ever "volunteer" again.
EDIT: I would also like to state that other than this one blot on the record, I greatly enjoyed my time in the military. I got to visit places I'm unlikely to see ever again, was given enormous responsibility, and had a job I truly enjoyed (most of the time). I met great people, and felt good about my contributions.
