US President Donald Trump has attracted condemnation from health experts after he sought to claim there was a link between the widely used painkiller Tylenol and autism.
Accompanied by his Health Secretary Robert F Kennedy Jr, Trump said doctors would soon be advised not to recommend the drug - called paracetamol in some other countries, including the UK - to pregnant women.
The claims have been attacked by medical experts. The American College of Obstetricians and Gynaecologists said the announcement was 'unsettling' and not based on 'reliable data', while the UK's National Autism Society called Trump's statement 'dangerous, it's anti-science and it's irresponsible.'
BBC Verify has looked at some of the allegations Trump and Kennedy made during their news conference at the White House.
Is Trump correct that US autism diagnoses are rising?
During the event, Trump listed a number of statistics which he said showed autism diagnoses in the US have risen rapidly over the past two decades.
The final statistic quoted by Trump - that autism rates have risen to one in 31 - is correct. Data from the Centers for Disease Control and Prevention (CDC) in 2022 found that level of diagnoses among eight-year-olds across 16 US states.
While that rate has grown from 18 years ago, it did not grow by anything like the figure cited by Trump.
Most experts say rising rates of autism can primarily be attributed to changes in how the condition is diagnosed, as well as greater recognition of the condition and more people being tested.
Should the MMR vaccine be taken separately?
Another claim made by Trump was around the effects of the mumps, measles and rubella (MMR) vaccine.
Experts fear that if parents refrain from getting their children vaccinated as a result of his unfounded claims, it risks the re-emergence of diseases like measles.
Multiple studies since have found no link between the MMR vaccine and autism. The US CDC recommends that two doses of the combined MMR vaccine are given to children.
Are autism rates lower among Amish people?
Trump cited the Amish as a group within the US who have 'virtually no autism'.
However, studies indicate that autism occurs in Amish communities, but reporting and diagnosis may differ significantly from mainstream society.
Trump's recent statements raise significant concerns about public health misinformation, requiring clarity and critique in the interest of public safety.
