US government report cited non-existent sources, academics sayUS Health Secretary Robert F Kennedy Jr, who has promoted debunked claims that vaccines cause autism, leads the department behind the report. A US government report on children's health cited "totally fabricated" studies to back up its findings, academics wrongly listed as the authors of those studies have said. But the authors of several studies cited in the report told news outlets they did not write them, and that the studies never existed. Another study cited about the advertising of psychotropic medications for youth was not written by the listed author, the university that employs him told AFP and Reuters. RFK Jr was sworn in as US Health Secretary in February.
