I don’t have allergies so I guess technically I am someone who is immune to pollen. If I understand it correctly, allergies are an over response by your immune system not a deficient one. So your ancestors probably evolved in an area with low pollen and now when you experience large amounts, your immune system is like, whoa I am not used to that better get it out of here with lots and lots of mucus.
