From December 2001 to May 2002, Afghan authorities and national and international organizations targeted 1,748,829 children aged 6 months to 12 years in five provinces in central Afghanistan for measles vaccinations. Two provinces reported coverage of 190% and two 180%. Coverage in Kabul city was 62%. A subsequent cluster survey in the city found 91% coverage (95% confidence interval [CI], 0.85–0.91) among children 6–59 months and 88% (95% CI, 0.87–0.95) among those 5–12 years old. Thus, this campaign achieved acceptable coverage despite considerable obstacles. by guest on July 28, 2015 Afghanistan, a landlocked central Asian country, shares In 2001, 8762 measles cases were reported from 328 borders with Pakistan, Iran, Turkmenistan, Uzbekistan, sites throughout Afghanistan established to conduct Tajikistan, and China.
