GENEVA, Sept 23, 2025 (BSS/AFP) - Neither the painkiller Tylenol nor vaccines 
have been shown to cause autism, the World Health Organization said Tuesday, 
following comments from the US president and his administration to the 
contrary.

WHO spokesman Tarik Jasarevic told reporters that while some observational 
studies had suggested a possible association of autism with acetaminophen, or 
paracetamol -- the primary ingredient in Tylenol -- others had "found no such 
relationship", adding: "The evidence remains inconsistent."

As for vaccines, he said there was no doubt: "Vaccines do not cause autism."
