This has never been my hobby horse to ride, nevertheless I find it very interesting that Tripedia has updated their product insert for their DTaP vaccine. From page 11:

Adverse events reported during post-approval use of Tripedia vaccine include idiopathic thrombocytopenic purpura, SIDS, anaphylactic reaction, cellulitis, autism, convulsion/grand mal convulsion, encephalopathy, hypotonia, neuropathy, somnolence and apnea. Events were included in this list because of the seriousness or frequency of reporting. Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequencies or to establish a causal relationship to components ofTripedia vaccine.

I state, once again, that autism has never been one of my concerns when it comes to vaccinations–I mean, look at the rest of the stuff on that list. But I find it interesting that a company is now putting autism in their product insert warning.
