No doubt you will eventually get one more cold virus, because there exist more than 300 different runny nose viruses. But you will certainly never acquire the very same runny nose virus that you had previously due to the fact that you have established immunity to that particular cold virus.Grownups have actually already had a great deal of the runny nose viruses. Parents have actually developed immunity to the viruses they have actually suffered from. Therefore there are not quite as many runny nose viruses around for grownups to become infected with. That is why parents just acquire a few colds each year and kids get a dozen runny noses each year.
