How do you know how bad it would have been had you not been vaccinated? I know of unvaccinated people that just had headaches or sniffles, or tested positive with no symptoms.
If it doesn't prevent the spread, then what is the logic between the mandates? If it's hospital capacity, then why did they fire so many unvaccinated nurses?
Even now, the electronic signs over the freeway that usually say stuff like COLLISION AHEAD or RIGHT LANE CLOSED, say VAX UP - STOP THE SPREAD OF COVID19. It's on TV commercials, too.
