Today, as the world commemorates World Polio Day with the theme, “One Day. One Focus: Ending Polio – delivering on our promise of a polio-free world!”, and Ethiopia launches a nationwide polio vaccination (nOPV2) campaign, we – the World Health Organization (WHO), UNICEF and ROTARY – reaffirm our commitment to continue delivering on our promise of a polio-free world for current and future generations.
