The terminology used makes it sound more chemical/technical/scary, but hydrolyzed gelatine is just another name for normal everyday gelatine - the same stuff you make jelly with.
Hah, well there you go then Thank-you! I haven't done any vacc research since DD1 was due for hers, I figure I've probably missed a whole bunch and maybe they'd changed the ingredients of some vaccines since I last checked, so yeah, this article and its fancy wording had me a bit stumped for a minute. I feel like a total douche now hahaha
I'm with Maz though... do we really need a scapegoat? Blaming this, that or the other doesn't help a child who is on the spectrum... sure, if a 'cause' can be determined that could prevent children suffering, I'm all for it, but most of the vax arguments I hear sound more like scaremongering to me (and yes, in this case I nearly fell for it! Oops!).
