That's not the only reasons people wouldn't want to take the vaccine. For instance lots of people already had covid (particularly in NYC), and developed a natural immunity, which from the low reinfection rate, seems to be rock solid. It doesn't make a lot of sense to require that population to take a vaccine.

As for the vaccine being more or less dangerous than the virus, I think for any population over 40 or in poor health, the trade off is clearly in favour of the vaccine. But if you are 20 and in good health, I am not sure it is that obvious.

I am not overly concerned about the vaccine myself, and I got vaccinated even though I had covid (mostly to be able to travel), but I have some sympathy for people who decline to be vaccinated, particularly when all the population at risk had a chance to get vaccinated. At this point this is them managing their own risk. Their life, their decision.
