Why do some people never get sick?
Doctors have noted natural variations in the immune response among people since Hippocrates’ time, but the reasons remained elusive for centuries. New research, however, is starting to illustrate just how your genes, habits and past disease exposures affect the character and strength of your immune response.
Does getting sick build immune system?
But while your immune system won’t have any specific “memory” of the virus, it will mount an immune response if you are infected — because that’s how your immune system works. Coming into contact with germs spurs an immune response, but it doesn’t do anything to make your immune system stronger.
