Realistically, what could the long term negative side effects of these covid vaccines actually be? I'm very skeptical of taking a rushed vaccine, especially since the companies making them are essentially liability-free and historically have been quite greedy. I see many people concerned about the potential long-term negatives of taking the vaccine, myself included, but I'm not really sure what these negatives COULD include.

Could someone smarter than myself explain to a humble retard what exactly these could be?
