Parents of children with autism are turning to a controversial stem cell treatment backed by the US health secretary. A number of clinics in the US are charging parents thousands of dollars for stem cell therapy, which is being given to children as young as 18 months. The Guardian’s chief reporter Ed Pilkington tells Kai Wright about his months-long investigation into the providers of these treatments and their relationship with Health Secretary Robert F. Kennedy Jr. He also spoke to those in the science community who fear the FDA might relax its strict restrictions on stem cell treatments for autism.
