High measles incidence and frequent epidemics are reported in Pakistan, given the low coverage for measles vaccine. This study evaluated coverage of mass measles campaign 2011 and estimated parental awareness and determinants for low/no coverage. Household survey was conducted 4 months after the measles campaign in Karachi, Pakistan. Parents of children younger than 5 years were administered structured questionnaire about their knowledge and participation in measles campaign. Of 1020 eligible households, only 282 (28%) parents knew about measles supplementary immunization activity, mainly from public announcements (49%). Of these, 174 (62%) children received measles vaccine, whereas, 108 (38%) parents refused measles vaccine. Overall, only 17% children received measles vaccine during this campaign. Low maternal education, not having received DPT/Pentavalent-3 vaccine, and routine vaccination from public Expanded Program on Immunization facility were significant determinants for low coverage. Measles vaccine coverage in Karachi remains low, and sporadic outbreaks of measles every 2 to 3 years are expected unless population coverage can be rapidly increased.
鉴于巴基斯坦麻疹疫苗接种覆盖率较低，该国报告了高麻疹发病率和频繁的疫情。本研究评估了2011年大规模麻疹疫苗接种活动的覆盖率，并估计了家长的知晓率以及低覆盖率/无覆盖率的决定因素。在巴基斯坦卡拉奇开展麻疹疫苗接种活动4个月后进行了家庭调查。对5岁以下儿童的家长进行了关于他们对麻疹疫苗接种活动的了解和参与情况的结构化问卷调查。在1020户符合条件的家庭中，只有282名（28%）家长知晓麻疹补充免疫活动，主要是通过公告得知（49%）。其中，174名（62%）儿童接种了麻疹疫苗，而108名（38%）家长拒绝为孩子接种麻疹疫苗。总体而言，在此活动期间只有17%的儿童接种了麻疹疫苗。母亲教育程度低、未接种百白破/五联疫苗3剂次以及在公共扩大免疫规划机构进行常规疫苗接种是低覆盖率的重要决定因素。卡拉奇的麻疹疫苗接种覆盖率仍然较低，除非能迅速提高人群覆盖率，否则预计每2至3年就会出现麻疹散发病例。
