Our science correspondent Tom Clarke is here and ready to answer your questions after Donald Trump’s bold claims on links to autism.
The US president has claimed the use of paracetamol in pregnancy is linked to an increased risk of autism.
Studies may have suggested a link, but they’ve been unable to show the drug itself led to autism instead of other factors.
Showing a correlation is not the same as finding a cause.
So what’s really going on here? And what does the evidence actually tell us?
Clarke will answer these – and many more – questions from 4.30pm. Submit your queries in the box above.
