No doubt you will eventually succumb to another runny nose virus, due to the fact that there remain more than 300 different runny nose viruses. Yet you will certainly never get the same runny nose infection that you had in the past due to the fact that you have created resistance to that cold virus.

Parents have previously had a lot of the runny nose viruses. Grownups have actually developed immunity to the ones they have suffered from.
