And sure you will possibly acquire one more cold virus, because there remain more than 300 various runny nose infections. However you will certainly never ever acquire the same cold infection that you had before since you have actually developed immunity to that virus.

Adults have actually already had a great deal of the cold infections. Grownups have actually established resistance to the colds they have suffered from. So there are not lots of cold viruses remaining for adults to catch. That is why grownups only get a few colds per year and kids may get 10-12 runny noses each year.
