I get allergies almost everyday because of dust/pollen. But I will not get chickenpox after being exposed to it once.

Because biology is weird!
An immunity and an allergy are actually kinda the same thing. When you get the chickenpox, you’re body learns and remembers how to fight the pathogen.
Allergic reactions are your body fighting things that don’t need to be fought. It tries to do a bunch of stuff to fight this thing that isn’t fighting back, but isn’t going away either.
Sometimes your body will realize it’s overreacting, and you outgrow the allergy. Unfortunately that’s not always the case, and requires several exposures.
