No doubt you will eventually get a different cold, since there remain 300 different cold viruses. But you will certainly never get the same runny nose infection that you had previously since you have created immunity to that particular virus.Adults have previously had a lot of the runny nose viruses. Adults have created immunity to the colds they have suffered from. Therefore there are not quite as many runny nose infections around for grownups to acquire. That is why parents just get a couple of colds each year and kids acquire 10-12 colds each year.
