By effective advantage I mean that if I catch a cold now and then recover fully, does this actually reduce my probability of catching a future cold. I understand that the body can build up anti-bodies and such, but pathogens also have the ability to mutate and I would assume that anti-bodies levels decrease over long periods of time. I am not a biologist! So feel free to correct my poor assumptions.
Thus taking those factors into account, are there models or data to argue that catching a cold gives me a future advantage over avoiding the cold altogether?
