Nature In a rare move for a US public official, health secretary Robert F. Kennedy Jr called for a Danish paper finding no link between aluminium in vaccines and disease to be retracted. US health secretary and vaccine sceptic Robert F. Kennedy Jr has called for the retraction of a Danish study that found no link between aluminium in vaccines and chronic diseases in children — a rare move for a US public official. Aluminium has been used for almost a century to enhance the immune system’s response to some vaccines. But some people claim the ingredient is linked to rising rates of childhood disorders such as autism.
Public-health officials in Kennedy’s position rarely request that studies be retracted, says Ivan Oransky, a specialist in academic publishing and co-founder of the media organization Retraction Watch. Through this request, “Secretary Kennedy has demonstrated that he wants the scientific literature to bend to his will”, says Oransky.
