Question Gradual exposure therapy for Coronavirus

Jul 2, 2020
Has the medical community considered a gradual exposure therapy approach to Coronavirus instead of vaccination?
I'm not a medical person, so certainly no one should try the idea, but it seems like it might work.
I'm thinking that since they say a low viral load will not infect you, perhaps the immune system will build up a defense if exposure is provided on a gradual basis.
Does anyone know if this has been considered?

I dont think that they know the necessary viral dose for infection yet, so even a small dose could potentially trigger a serious infection and significant immune response in some or many people. Its just not a very safe way to induce immunity.
