If I could live my life over again, I would devote it to proving that germs seek their natural habitat — diseased tissue — rather than being the cause of the diseased tissue; e.g. mosquitoes seek the stagnant water, but don't cause the pool to become stagnant. - Rudolph Virchow, Father of Pathology

You're correct, though an overactive immune system can only happen due to disease already having taken hold in the first place.
A key takeaway from this Rudolph Virchow quote should be that the immune system is a backup that takes over after the environment has become diseased. It's not the firewall which prevents disease.
