Immune systems of healthy adults 'remember' germs to which they've never been exposed
It's established dogma that the immune system develops a "memory" of a microbial pathogen, with a correspondingly enhanced readiness to combat that microbe, only upon exposure to it—or to its components though a vaccine. ...
