Ethiopia kicked off the second round of a polio vaccination drive April 15, targeting 16 million children under age 5 with nOPV2 drops. The campaign was conducted April 15-18 in all regions except Addis Ababa, Afar, and Tigray. Those three regions—which carried out the first round of the campaign in early April—will administer vaccines in May to adhere to the required four-week interval between the first and second doses.
