You don't have a right to not be exposed to free-range germs. No one has a right to spit in your face to expose you to their germs, but people have to breathe and this means germs are out in the real world. Otherwise, you would have no immune system. You can't have a right to enslave others because you're scared of germs. That includes using legislation to force them to mask or to vaccinate. You have the right to avoid others if you're worried.
