Robert F Kennedy Jr is one of the world’s most prominent vaccine sceptics, and now the founder of the anti-vaccine group Children’s Health Defense has been nominated by president-elect Donald Trump as his chosen Secretary of Health and Human Services.

In Mr Trump’s own words, at a rally two days before the US election, the plan is to let Mr Kennedy “go wild on health” and “wild on medicines”.

“The only thing I don’t think I’m going to let him even get near is the liquid gold that we have under our feet,” Mr Trump said.

Mr Kennedy’s nomination has to be endorsed by the Senate.
