Overview

• At a White House appearance with Health Secretary Robert F. Kennedy Jr., the president said prenatal acetaminophen use is associated with higher autism risk and recommended restricting Tylenol except for extreme fever.
• Trump also said there is no reason to vaccinate newborns against hepatitis B and suggested waiting until age twelve, a position that runs counter to guidance favoring vaccination at birth to prevent maternal transmission.
• ACOG and the Society for Maternal-Fetal Medicine said evidence does not establish causation and continue to list acetaminophen as among the safer options for pain and fever during pregnancy.
• Maternal-fetal specialists cautioned that untreated high fever in pregnancy can increase risks such as miscarriage and preterm birth.
• Kenvue, maker of Tylenol, said the autism claim lacks a scientific basis as its shares fell about 7.5 percent, and separate reporting said the White House plans to study leucovorin as a potential autism therapy.
