President Donald Trump’s Monday comments about autism and public health were filled with misinformation that left many doctors aghast – and not just about Tylenol.

Most of the media coverage of Trump’s press conference centered around his repeated advice to pregnant Americans to try to avoid taking Tylenol, which he based on a supposed link to autism that has not been proven. But the president also made a series of additional comments about autism, vaccines, and hepatitis B that ranged from unproven to misleading to false.

Trump said he has “been hearing” that the combination measles, mumps and rubella (MMR) vaccine is “bad” and called to split it up into separate shots. But the combination has proven safe and effective since it was approved in the 1970s, and it has no link to autism.

Trump said there is “no reason” to vaccinate a newborn for hepatitis B given that the virus is sexually transmitted, and he called to delay the first dose until age 12. But there is a very good reason to give the vaccine to babies: The virus can also be transmitted from mother to child at birth and through contact with small amounts of blood on common household items.

Trump greatly exaggerated how many shots babies receive – it’s nowhere near the “80” he claimed – and wrongly suggested numerous different vaccines are drawn from the same “vat.” He greatly exaggerated how rare autism was “18 years ago.”

He cited “the Amish” as a group “that don’t take vaccines and don’t take any pills,” though many Amish people do take vaccines and pills, and added that they “have essentially no autism,” though there are Amish people with autism. There is no known connection between any community’s autism prevalence and its use of vaccines or certain pills. And he similarly cited a “rumor” that Cuba has “no Tylenol,” though the generic version is widely available in Cuba, and that Cuba has “virtually no autism,” though Cuba does have autism and though lower-income countries’ low known autism levels are generally connected with a lack of resources to diagnose cases.
