>>13465992Well, theres some evidence that Covid attacks brain cells, it's been linked to dementia, possibly autoimmune disease, lung scarring and some other nasty stuff. Without a vaccine your body will get infected, hypothetically in the same way as a vaccinated person even, but it wont provide a strong enough immune reaction to prevent damage to your body. Covid appears to be a heavily inflammatory based disease, it doesn't seem to provoke a normal adaptive immune response.
This is to say getting reinfected without a vaccine will cause significantly more damage to it in the long run than if you got vaccinated. You're just putting yourself at risk of autoimmune disease later on.
