Older people have to get the vaccine. It's ok for young people to catch the virus, over and over again, but not the elderly. The Covid virus causes problems with the lungs and older people struggle with breathing.viruses ALWAYS mutate quickly that is why you CAN'T and shouldn't even try to make a vaccine for them, you keep the immune system built up, EVERY group in the military gets sick right away in boot camp, then they get well and go on with training, if you go over 200 miles from home you get exposed to viruses you don't have the strongest immunity for, and this happens.
we learned this in junior high for goodness sake.
If your over 60 don't catch covid and especially not a second time.
