No doubt you will eventually get a different runny nose virus, since there are over 300 different runny nose viruses. However you will certainly never get the exact same cold virus that you had before since you have created immunity to that cold virus.Adults have in the past had a great deal of the runny nose viruses. Parents have created immunity to the colds they have had. Therefore there are not so many cold viruses remaining for adults to acquire. That is why adults only get infected with a few runny noses annually whereas kids acquire 10-12 colds each year.
