Abstract
BackgroundIn order to control and eliminate the vaccine preventable diseases it is important to know the vaccination coverage and reasons for non-vaccination. The primary objective of this study was to determine the complete vaccination rate; the reasons for non-vaccination and the predictors that influence vaccination of children. The other objective was to determine coverage of measles vaccination of the Measles Immunization Days (MID) 2005 for children aged 9 month to 6 years in a region of Umraniye, Istanbul, Turkey.MethodsA '30 × 7' cluster sampling design was used as the sampling method. Thirty streets were selected at random from study area. Survey data were collected by a questionnaire which was applied face to face to parents of 221 children. A Chi-square test and logistic regression was used for the statistical analyses. Content analysis method was used to evaluate the open-ended questions.ResultsThe complete vaccination rate for study population was 84.5% and 3.2% of all children were totally non-vaccinated. The siblings of non-vaccinated children were also non-vaccinated. Reasons for non-vaccination were as follows: being in the village and couldn't reach to health care services; having no knowledge about vaccination; the father of child didn't allow vaccination; intercurrent illness of child during vaccination time; missed opportunities like not to shave off a vial for only one child. In logistic regression analysis, paternal and maternal levels of education and immigration time of both parents to Istanbul were found to influence whether children were completely vaccinated or non-vaccinated. Measles vaccination coverage during MID was 79.3%.ConclusionEfforts to increase vaccination coverage should take reasons for non-vaccination into account.
Highlights
In order to control and eliminate the vaccine preventable diseases it is important to know the vaccination coverage and reasons for non-vaccination
High vaccination coverage is important in control and elimination of vaccine preventable diseases in a country
The region still receives a high rate of immigration from less developed parts of the country and primary level health care services are provided through only one health care center which is active since 2001
Summary
In order to control and eliminate the vaccine preventable diseases it is important to know the vaccination coverage and reasons for non-vaccination. The other objective was to determine coverage of measles vaccination of the Measles Immunization Days (MID) 2005 for children aged 9 month to 6 years in a region of Umraniye, Istanbul, Turkey. The region still receives a high rate of immigration from less developed parts of the country and primary level health care services are provided through only one health care center which is active since 2001. This health center provides ambulatory care, immunizations, reproductive health services and health education. The Umraniye Health District reported in 2002, the full vaccination rate in our study area as 53.8%, which indicates that there is still a big gap between EPI targets and vaccination coverage rates in our study area
