A vaccinated person with their guard down is less risk to society than an unvaccinated person with their guard up. This is a respiratory disease. It spreads via spit you exhale as moisture in the air. That moisture is a gas. Gasses expand and dilute to fill the volume containing them. When outdoors, that's great. Plenty of room to expand into and dry out and die before getting to another person's lungs. In a closed room, we're all breathing the same air. The odds that spit from your lungs makes it into someone else's lungs is almost guaranteed.

You don't need physical contact, or blood contact. You only need to inhale an invisible amount of moisture.
That's why an unvaccinated person shouldn't be allowed in indoor spaces during a respiratory pandemic.

Not suffering from a fever means the infection you're experiencing is not threatening your life to the point where your body is willing to self-immolate in an effort to kill the virus before killing itself. Having a fever is not something you want. Having a fever means your body cannot fight the infection with anti-bodies and it has to resort to more extreme measures. Those measures can damage your own cells, can cause brain damage if the fever is too high for too long.

I agree, that if the pandemic ends and the vaccine requirement stays, that'd be wrong. It's purely hypothetical at this time.

COVID vaccines have been put to the general public and billions of people have received the vaccine. What greater "safety" trial can you cite from the history of vaccination? Sure, 2 years ago the vaccine was totally untested. But not anymore.

Your failure to look at what scientists and epidemiologists are saying about the effectiveness of the vaccine is on you. I agree that trusting politicians, the pharma companies, or the media to get this information is sketchy at best. There are real experts who, in the course of their professional licensing have sworn to "do no harm" talking, too. Please learn what they have to say and what THEY mean when they say the vaccine is effective. "Effective" doesn't mean 100% perfect. It means you're much safer with the vaccine than without it.

I have explained how being in a crowded indoor space is putting everyone there at risk. If you catch the disease from someone taking what measures they have been advised to take to prevent you getting sick, then no, you can't really blame them for a microscopic, invisible thing getting from them to you. However, if they're pissing and moaning about how your health and not being infected is beneath their sense of personal freedom, then yeah. Their bravado and idiocy has infected you with a potentially fatal disease and they claim it's their right to do that to you, then fuck them.

Again, I agree that if these restrictions persist after the virus is eradicated, then that would be a new problem to fight against. Right now, that is still a hypothetical. Right now, people are still dying to COVID. Right now, the experts in stopping this are saying to get a vaccine and practice social distancing and wear a mask when indoors.
