New York Times

• "This journey was the consequence of a fateful decision by global health organizations to pare down the oral polio vaccine in 2016. The move, now called “the switch,” was intended to help eradicate the disease."
• "Instead, the change has led to outbreaks of polio in dozens of countries and has paralyzed more than 3,300 children.

• "The switch, in April 2016, was a remarkable event, with 155 countries and territories simultaneously replacing triple-hit vaccines with two-hit ones in two weeks."
