Deer continued his reporting in a Channel 4 Dispatches television documentary, MMR: What They Didn't Tell You, broadcast on 18 November 2004. This documentary alleged that Wakefield had applied for patents on a vaccine that was a rival of the MMR vaccine, and that he knew of test results from his own laboratory at the Royal Free Hospital that contradicted his own claims.[3] Wakefield's patent application was also noted in Paul Offit's 2008 book, Autism's False Prophets.
