• The World Health Organization responded that studies are inconsistent and cautioned against concluding causation, reiterating that vaccines do not cause autism.
• The administration spotlighted an FDA notice approving a leucovorin product for cerebral folate deficiency, though experts say preliminary studies do not establish it as an autism treatment.
• The American College of Obstetricians and Gynecologists and maternal–fetal specialists continue to advise acetaminophen as the preferred option in pregnancy when needed, warning that untreated fever carries known risks.
• Tylenol maker Kenvue rejected a causal link and its shares fell about 7.5% on Monday, while Trump also questioned standard childhood vaccination practices, including delaying the hepatitis B shot for newborns.
