Though "Pakistan has made a lot of progress this year in wiping out polio," a "recent outbreak of polio there has health officials concerned about the overall effectiveness of the effort to eliminate polio in that country," NPR's "Shots" blog reports. According to the WHO, "10 cases of so-called vaccine-derived polio were reported in Pakistan between the end of August and the end of October," the blog notes, adding this is the first time vaccine-derived polio has been detected in the country and it is a sign of gaps in immunization coverage. "WHO officials say the outbreak, involving a variety of the virus called type 2 polio, illustrates that vaccination campaigns in the area are failing to reach sufficient numbers of people," the blog writes. "The government of Pakistan launched an aggressive campaign this year, in partnership with international health organizations, to vaccinate children and carefully monitor the virus's spread," according to "Shots" (Beaubien, 12/4).
