During his trip to Asia on Sunday, President Donald Trump drew widespread criticism after posting a controversial message on his Truth Social platform. In the post, Trump warned pregnant women against taking Tylenol “unless absolutely necessary” and suggested parents should split the measles, mumps, and rubella (MMR) vaccine into three separate doses rather than using the standard combined shot.
The post included a link to an article from the MAGA-aligned outlet The Daily Caller, which questioned potential links between Tylenol use and autism. Health Secretary Robert F. Kennedy has previously attempted to connect prenatal Tylenol exposure to autism rates in the United States, but health experts have repeatedly dismissed such claims as misleading and unscientific.
Medical professionals quickly condemned the post, saying it spread dangerous misinformation. Numerous studies have found no credible evidence supporting a link between either Tylenol or vaccines and autism. The Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) both maintain that vaccines are safe and essential to public health.
Observers across social media reacted sharply to Trump’s remarks. Journalist Aaron Rupar called the post “complete bat — insanity.” Journalist Duncan Smith wrote, “Well, he still doesn’t know how to spell ‘pox.’” Musician Troy Westwood added, “Dr. Orange Clown.”
Robert Manning, a distinguished fellow at the Stimson Center, wrote, “His MOBIS (sic) to manufacture a fictional alt reality— and get you to believe it.” Journalist Laura Rozen added, “In lieu of negotiating a way to help Americans pay for health care, Trump is offering medical disinfo and conspiracy theories.”
Criticism continued on Bluesky, where the political blog Blue Virginia posted, “Yep, our president is stark raving mad – that’s undeniable at this point. Also, he can’t spell (‘hepatitas’?), and why does he WRITE IN ALL CAPS? So in addition to being stark raving mad, he’s an imbecile, ignorant, etc.” Journalist Amanda Moore asked, “Is Tylenol going to sue or what?”
Trump’s comments reignited concerns about his history of promoting false medical information. During his presidency, he made several misleading claims about vaccines and treatments, including comments suggesting disinfectants could combat COVID-19.
Public health experts warn that such statements can erode trust in science and endanger lives by discouraging vaccination and safe medical practices. Despite mounting backlash, Trump has not retracted or clarified his Truth Social post.
The incident adds to growing worries among health officials that political rhetoric continues to undermine public confidence in medical science at a time when misinformation remains one of the nation’s leading health challenges.
