And of course you will probably acquire another cold virus, because there remain more than several hundred different runny nose viruses. Yet you will unlikely get the very same cold infection that you had in the past because you have actually established immunity to that cold virus.

Grownups have actually previously had a great deal of the runny nose viruses. Parents have actually acquired immunity to the viruses they have actually had. Therefore there are not quite as many runny nose infections existing for adults to catch. That is why grownups just acquire a couple of colds annually and children usually get 10-12 colds per year.
