And of course you will eventually cave in to another cold virus, because there are several hundred various runny nose infections. However you will never ever get the same cold infection that you had previously since you have actually established immunity to that particular cold virus.Adults have currently had a great deal of the cold viruses. Adults have created resistance to the viruses they have suffered from. Therefore there are not lots of cold infections existing for grownups to catch. That is why adults only succumb to a couple of runny noses per year whereas children acquire 10-12 colds per year.
