go to /r/nursing and sort by top of all time and just read the posts and the respective top comments, most of it is about covid patients and how absolutely awful the situation is
most people think that getting covid is a black and white case of either dying with a chance of around 2 % or surviving and being perfectly fine, when in reality you might get permanent lung damage, making a walk from your bed to the kitchen seem like running a maraphon
or get brain damage from hypoxia, so that you get what's called brain fog, meaning that your consciousness will be clouded for an unknown time
or any number of yet undescovered side effects
tldr iirc there is a small chance to get sick from a vaccine, but there is an exponentially higher change to get sick without a vaccine and suffer much worse consequences
