How long until this becomes an available option??

I don't think they know how long yet. It's still in clinical trials.

I will be watching this like a hawk...My son has had the peanut allergy all his life along with non verbal autism...getting rid of this allergy is hugely important to me due to him someday living in a group home type setting and not having to worry about the staff feeding him the wrong thing and killing him....the autism I can handle...its not going to kill him, but the peanuts will.

I can see where a food allergy would be a huge challenge in that type of environment!
