“…Although China has made great progress in measles control in the framework of the NMEP, the average reported rate of measles was 28 cases per million in China in 2010, still far above the WHO’s recommended rate of one case per million. Similar to other countries [3], increasing population mobility coupled with low routine vaccination coverage of migrants has been identified as one of the key contributors of measles outbreaks in China [4]. The vaccination coverage of migrant children is much lower than that of local children [5], mainly as a result of migrants’ high mobility, low socioeconomic status, lower level of knowledge and awareness about vaccination, and insufficient access to vaccination services in receiving areas [6].…”

BackgroundThe reported coverage rates of first and second doses of measles containing vaccine (MCV) are almost 95% in China, while measles cases are constantly being reported. This study evaluated the vaccine coverage, timeliness, and barriers to immunization of MCV1 and MCV2 in children aged from 8–48 months.MethodsWe assessed 718 children aged 8–48 months, of which 499 children aged 18–48 months in September 2011. Face to face interviews were administered with children’s mothers to estimate MCV1 and MCV2 coverage rate, its timeliness and barriers to vaccine uptake.ResultsThe coverage rates were 76.9% for MCV1 and 44.7% for MCV2 in average. Only 47.5% of surveyed children received the MCV1 timely, which postpone vaccination by up to one month beyond the stipulated age of 8 months. Even if coverage thus improves with time, postponed vaccination adds to the pool of unprotected children in the population. Being unaware of the necessity for vaccination and its schedule, misunderstanding of side-effect of vaccine, and child being sick during the recommended vaccination period were significant preventive factors for both MCV1 and MCV2 vaccination. Having multiple children, mother’s education level, household income and children with working mothers were significantly associated with delayed or missing MCV1 immunization.ConclusionsTo avoid future outbreaks, it is crucial to attain high coverage levels by timely vaccination, thus, accurate information should be delivered and a systematic approach should be targeted to high-risk groups.

“…Despite China’s great progress across a range of health indicators in the past decades [4], measles incidence, though fluctuating in the past two decades, has remained high. Similar to other countries [5], increasing population mobility coupled with low routine vaccination coverage of migrants has been identified as one of the key contributors to measles outbreaks.…”

Objective: To determine the coverage of childhood immunization appropriate for age among socio-economically disadvantaged recent migrants living in East China and to identify the determinants of full immunization uptake among these migrant children. Methods: This is a cross-sectional survey of 1,426 migrant mothers with a child aged ≤24 months, who were interviewed with a pretested questionnaire. Various vaccines, migration history and some other social-demographic and income details were collected. Single-level logistic regression analyses were applied to identify the determinants of full immunization status. Results: Immunization coverage rates are lower among migrants and even lower among recent migrants. The likelihood of a child receiving full immunization rise with parents’ educational level and the frequency of mother’s utilization of health care. Higher household income also significantly increase the likelihood of full immunization, as dose post-natal visits by a health worker. Conclusions: Recent migrant status favours low immunization uptake, particularly in the vulnerability context of alienation and livelihood insecurity. Services must be delivered with a focus on recent migrants. Investments are needed in education, socio-economic development and secure livelihoods to improve and sustain equitable health care services.

“…It has been reported that the cases observed immediately following supplemental immunization tend to be due to immigration from nearby areas where it has not taken place. 43 Our findings suggest that both the build-up of a susceptible population due to poor vaccine coverage and high population density contributed to the South African outbreak. Similarly, the large measles outbreak in Sierra Leone during 2009 and 2010 was probably caused by the accumulation of susceptible individuals, largely due to nonvaccination.…”

Migration as a risk factor for measles after a mass vaccination campaign, Burkina Faso, 2002†

Abstract: Migration of children between Cote d'Ivoire and Burkina Faso played a major role in the failure of the SIA to interrupt measles transmission. Synchronization of measles control activities should be a high priority in countries with regions where much migration occurs.
