Trump says he will demand some childhood vaccines be split into five shots

Sept 18 (Reuters) – US President Donald Trump said on Friday that his administration plans to demand vaccine makers split certain childhood ​shots into five separate doses, which ‌he believes will result in a massive reduction in autism, an idea repeatedly debunked by scientists.

Trump did not provide any scientific evidence linking vaccines and autism. Nor ‌did ​he say which vaccines the ⁠administration plans to ⁠split into smaller doses.

“We’re going to recommend that they do five doses … and that they be given in six-month intervals so that a ​small amount of the vaccine gets pumped into the body,” Trump said, speaking at ⁠an event in the ⁠Oval Office.

Trump already signed an executive ​order in August calling for fewer childhood vaccinations by ​limiting the inoculation schedule to 11 immunizations, ‌which he said would give US children “gold-standard” protection and align the country with peer nations that recommend fewer shots.

That order directed Americans to ⁠receive separate measles, mumps and rubella vaccines even though none of the individual shots are licensed in ⁠the United States ‌and experts say it could ⁠take years before any become available, ​if ‌they ever do.

The order advances a ​long-standing goal ⁠of Health Secretary Robert F. Kennedy Jr., an anti-vaccine activist who has promoted a link between vaccines and autism that scientists have repeatedly debunked.
