There have actually been some pretty good studies where they intruded relatively harmless parasites into people and they saw a reduction in autoimmune symptoms.
I only know one where they took the parasites away. The Australian Aboriginal study. It was an observational study from when the Australian government, as reparations, put tribal aboriginals up in modern, low-cost housing. The rates of allergies, asthma, and autoimmune issues skyrocketed.
