Colloidal Silver/Immunity to colds?

Hi, when you use Colloidal Silver to get rid of a cold (drops or spray up nose etc.) do you still get immune to that specific strain of cold virus the same way you do if you actually GOT the cold and your body fought it off? For example while you're using the silver is your body also fighting the virus so you become immune.
I am wondering if say someone at my work has a cold and I start getting it too, and I use the silver and the cold goes away. The next week someone at my house gets the same cold virus, would I start coming down with the same one again because my body didnt actually do the fighting because the silver killed all the germs? I want to use it but I dont want to keep fighting the same cold every time I'm around someone who has it, i'd rather get the cold once and be done with it.. if that makes sense. Tweet
