But a vaccine does something analogous: it "exercises" the immune system (hopefully harmlessly) to strengthen it for when real pathogens are encountered.

So between vaccines, and natural immunities developed by exposure to and recovering from a disease, the "getting stronger with use" comparison is generally correct.

But it isn't the "exercising" of the immune system that provides the benefit, it's training it to recognize a new virus. If that could be done without a huge immune response it would be just as effective. The immune system isn't any stronger after a vaccination, it's just smarter. Presumably exposing the immune system to several unrelated viruses provides no benefits as to how it can deal with the target virus.

unlikely you could achieve that given that vaccine manufacturers purposely add adjuvants to annoy your immune system to in turn create a stronger immune response for higher antibody titers, which last longer.
