A polio team, accompanied by an armed escort, vaccinates children in a nomad community during a national polio immunization campaign in Pakistan in 2013 in this week’s Photo of the Week taken by Asad Zaidi . The world is closer than ever to eradicating polio. Just three endemic countries (including Pakistan) remain.
Acceptance of the polio vaccine in these countries has reached record highs through intense UNICEF-led social mobilization. World Polio Day, held annually on 24 October, focuses this year on the final push to end the crippling disease.
