Answer 1

You will build up an immunity over time. That’s how allergy shots work. The problem is that most allergens are things we rarely come into contact with. For instance a certain tree might release its pollen for 2 weeks a year. Whatever immunity you started building up will be lost during the 50 weeks until it releases pollen again.
