And sure you will eventually cave in to one more cold virus, due to the fact that there remain over 300 different cold infections. But you will certainly never ever acquire the exact same runny nose virus that you had in the past due to the fact that you have created resistance to that cold virus.

Parents have actually currently had a lot of the rhinitis viruses. Adults have established resistance to the colds they have actually suffered from. So there are not quite as many runny nose infections around for grownups to catch. That is why adults only acquire a few runny noses annually and youngsters usually get 10-12 runny noses per year.
