Oh, Alison, I'm so sorry to hear this. How many doses had your boy taken before this developed? By any chance, had he had a vaccination or a HW "med" before he broke with the autoimmune illness that ended up taking his life? If Apoquel is associated with autoimmune disease, we need to catalog more cases. It makes sense that it could: it's targeting the immune system to suppress it, that's a given.
I applaud you for sharing this with us, as we need to hear more of these stories to better understand our risks out there.
