I had many pollen allergies. Every spring was unpleasant. I decided to go to an allergist and take allergy shots, which amounted to repeatedly injecting allergens into me. As a result of these repeat antigen shots, my immune system developed non-inflammatory IgG4 antibodies, which mark pollen as a harmless substance to the rest of my immune system and prevent allergic inflammation and nasty symptoms.
There is something important, though: pollen does not replicate.
It is a good idea not to have inflammation in response to pollen. It is a bad idea, however, to train our immune system to ignore replicating pathogens such as Sars-Cov-2.
