There’s something I don’t understand. I took allergy shots to treat my sinus allergies to grass pollen, pet dander, and rag weed. It’s not perfect but it built up my tolerance to these so that I can have cats and survive grass season. Why can’t a similar treatment work for food allergies.
The good news is that if you diagnose food allergies early and start someone on oral immunotherapy when they’re extremely young (The downside is they have to continue their daily dose forever. There are some interesting alternatives coming into the market though.
Edit: they will still need to always keep epipens nearby, but at least now there’s no fear of anaphylaxis when someone nearby on the plane eats a bag of peanuts.
