And of course you will most likely get one more cold virus, because there remain over 300 different runny nose viruses. Yet you will certainly never ever get the very same runny nose infection that you had before due to the fact that you have actually established immunity to that particular cold virus.

Parents have currently had a lot of the cold viruses. Adults have actually created immunity to the ones they have suffered from. So there are not as many cold infections existing for grownups to acquire. That is why grownups just acquire a few colds annually whereas children acquire 10-12 runny noses annually.
