It is not well known but this also works for adults too. I’m 28 and recently completed oral immunotherapy therapy for my extremely severe peanut allergy. I used to go anaphylactic from single milligram exposure and now I’m eating multiple peanuts a day. As an adult you have to go slower and be more careful but absolutely can be done and is life changing.
Wonderful to hear - my son took part in a milk desensitisation, which has been really successful - but he also has a good few other food allergies. We haven't yet been able to get him onto other trials, so I was worried that if we didn't do it while he was young, we'd miss the 'window'.
Brilliant to hear it still works well in adulthood - if we can get peanuts, sesame and egg under control - so that he can eat 'May Contain' food, that would be a huge change for him.
About a year overall but I started to have meaningful protection after about 6 months. There is no one in the UK currently offering it for adults so I had to travel to a specialist clinic Atlanta a few times.
