WASHINGTON: US President Donald Trump on Monday linked autism to childhood vaccines and also to the use of popular pain medication Tylenol for pregnant women and children, claims which are not backed by decades of science. In an extraordinary news conference at the White House, the Republican president delivered medical advice to pregnant women and parents of young children, repeatedly telling them not to use or administer the over-the-counter pain killer.
