Advice on granuloma?

[Arete]

I've been doing a very selective/delayed schedule with my son, David, 7 months (who has Down syndrome and is thus at higher risk for autism).  Our doctor is very supportive, but one she did advise we do is the DTaP.  At his last dose, he developed a granuloma which was not at all painful or inflamed, but just a lump.  At the time I didn't think much of it, but now, with his next shot scheduled for next week, I happened to read that this is an indication of vaccine sensitivity, and I am freaking out!  Any advice???

This is mostly likey a reaction to the aluminum in the Dtap.

This is an indication your DS has a sensitivity to aluminum. Persoanlly I wouldn't give another aluminum based vaccine.
