I've read your concerns and take the gravest possible offense to this. It's not just about the new coronavirus, but what comes next. Tools like crispr are now within the means of the nuclear boyscout, who can unleash an airborne pathogen upon humanity that performs genetic engineering at scale. All that's required is the will to do so. Stuff like that frightens me far more. If the reaction to this new coronavirus is what's needed to help humanity prepare, then we're likely to be far safer and healthier down the road.
If only the global attention and resources that have gone into the covid crisis could be channelled into the many equally, or more serious issues affecting humanity and the planet today (e.g poverty, oppression, war, over population, pollution, tuberculosis etc.). But they are not the new hot shiny problem, just our boring, faulty and irreplaceable legacy system.

The thing about the flu is that you develop symptoms earlier, so the window of oportunity for unknowing transmission is shorter (on average). From what we know at this time, it's a less deadly disease than COVID-19. And it mutates quickly, with each season bringing new strains. I think if it was possible to erradicate it completely through vaccination that would be something worth considering, too. Nobody likes that it exists.

For the record, vaccines are not a controversial topic in my country like they seem to be in the USA. Kids are vaccinated at school, I received numerous vaccines during my life, some of them totally optional and quite expensive, which I paid for anyway, because it felt like a safer way to be. And of course I do not think vaccines are an evil plan of Bill Gates to... I'm not even sure what the crazy conspiracy theory about that is supposed to be, but I'm pretty sure there is some.
But I am a crazy conspiracy theorist in a sense that I firmly believe that COVID-19 is hugely overhyped. Of course, I'm scared and ashamed of saying that, because nowadays this seems to be a stronger version of saying "Hitler did nothing wrong", but you are asking about "why no", so here we are.
Basically, it's a trade off between reasons to do it and reasons not to (as always).
Is there a reason to avoid doing it? Well, yes. Basically, expectation that everyone should do it is that reason: the topic is insanely hot, and it's never a good thing. This is a huge business opportunity for every pharmaceutical company that gets to push their vaccine right now, and this is some hastily cooked shit you expect me to take. Some of these vaccines are quite a novelty, which is not a bad thing on its own, but this is unlike most vaccines I have ever taken, which are basically decades old and literally millions of people have taken them before me. Maybe it's totally safe, maybe it isn't. No couple-months-long trial will ever answer that.
Is there a reason to take it? Well, sure. Like there is a reason to take a flu vaccine. Which I don't do, because there are new mutations every year, and there are countless more versions of "common cold". Yes, people die of that, and it's never a pleasant experience, and I live in a cold climate, where this is a very common seasonal thing, but it's just how things are. It's ok. And I'm not going to elaborate on all "Hitler did nothing wrong" thing, because what I've said so far is more than enough to trigger someone, but, well, I know people that had been sick with COVID-19. I contacted them in person when they were already sick, and it just so happens that neither of us was wearing any mask. I wasn't really a responsible citizen all the time. It doesn't seem that the stakes are much higher than with a flu. For some of people it seemed to be more like a really light version of a common cold.
So there's a little of "no" vs a little of "yes" and it just so happens that "no" overweights quite confidently.
Maybe it is fair to say that I should've voted "I'll wail", because this "no" isn't final. But then no "yes" is final either, anything can happen, the last year should've taught us that if anything. And I don't have any specific date I have to wait for. The point is, currently I'm not going to do that, and I hope it stays this way.
