This vaccine coverage cluster survey was conducted in nine governorates representing areas outside governmental control, where EWARN, SIG and other NGOs are operating. The overall purpose of this cluster survey is to provide information on vaccine coverage of children under 5 years of age who are
living in military conflict-affected areas in northern Syria and thought to be either deprived from health care services including vaccination or receiving late vaccine doses at ad hoc basis and remain susceptible to vaccine preventable diseases for long time. This information is collected to guide decision-makers of local authorities, WHO, UNICEF and all other partners included in Syrian Immunization Group and beyond. The specific objectives are to assess vaccine coverage among different age groups (12-23 and 24-59 month of age) including mothers who gave birth for children 0-11. in addition, the survey will provide information on reasons of un-vaccination and advise on gaps that need to be covered as well as help in future planning. The sampling frame was developed where each district/sub-district was considered one stratum and a sample was selected independently from each stratum.
