We analyzed polio incidence and polio vaccination data from 32 districts of northwest Pakistan and constructed a measure of insecurity based on journalistic reports of deaths and injuries resulting from conflict-related security incidents. Insecurity was associated with reduced vaccinator access, reduced polio vaccination, and increased polio incidence. These findings provide strong scientific evidence that insecurity is an important obstacle to global polio eradication.<\/jats:p>","DOI":"10.1073\/pnas.1711923115","type":"journal-article","created":{"date-parts":[[2018,1,29]],"date-time":"2018-01-29T15:15:30Z","timestamp":1517238930000},"page":"1593-1598","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":36,"title":["Insecurity, polio vaccination rates, and polio incidence in northwest Pakistan"],"prefix":"10.1073","volume":"115","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6857-931X","authenticated-orcid":false,"given":"Amol A.","family":"Verma","sequence":"first","affiliation":[{"name":"Li Ka Shing Centre for Healthcare Analytics Research and Training, St. Michael's Hospital, Toronto, ON M5B1W8, Canada;"},{"name":"Eliot Phillipson Clinician-Scientist Training Program, Department of Medicine, University of Toronto, Toronto, ON M5G 2C4, Canada;"},{"name":"St. Hilda's College, University of Oxford, Oxford OX4 1DY, United Kingdom;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcia P.","family":"Jimenez","sequence":"additional","affiliation":[{"name":"Department of Epidemiology, Brown School of Public Health, Brown University, Providence, RI 02912;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rudolf H.","family":"Tangermann","sequence":"additional","affiliation":[{"name":"Independent scholar;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
