Which brings it all back to a lack of trust in the vaccine/science. The current science is that the vaccines are safe and provide a greater degree of protection than prior infection alone. Outside of some very rare conditions that would make someone unfit for a vaccine, there's no reason not to get vaccinated. Refusing to get one only increases your chances of ending up in a hospital and for what? There's no advantage to giving yourself a disadvantage no matter how small you think the benefit a free vaccine would give you over the protection a natural infection has already given you.
