This is not a particularly strongly true statement, and in fact there is quite a lot of evidence that for the vast majority of coughs/colds/viral infections it is in fact false. This is evidenced by the surge in infections a child (or a new nursing or medical student) receives on starting daycare/hospital. For sure COVID and the Flu have significant flow on effects to the population but COVID aside (there is some weird evidence coming through about repeated infections in different populations here) having an infection pretty much always results in a significantly reduced second round (or you are, in fact, immune)

> This is evidenced by the surge in infections a child (or a new nursing or medical student) receives on starting daycare/hospital. I don't think this is evidence that getting sick as a nurse in daycare is good for you. This only evidences that people adapt to an repeat infection and environment with pathogens. The comparison should be made against a person that never had to go to daycare and never had to get sick there -> would they be more or less healthy. I am not an immunologist of-course, but everything I read indicates that this conventional wisdom is build on misunderstanding of the immune system .
