An assessment of factors associated with full vaccination coverage rate among children aged 12-23 months in Masvingo district; Zimbabwe. A cross-sectional study
Abstract
Introduction: Immunization is one of the most cost-effective nursing interventions aimed at reducing ill health and premature death among children. Despite tremendous efforts by governments, vaccination coverage remains low, especially in developing countries. Masvingo district is one of the districts with low vaccination coverage in the country. Objectives: This study sought to assess immunization coverage, identify determinants of vaccination coverage and assess factors associated with low full immunization coverage in Masvingo district, Zimbabwe. Methods: An analytical cross-sectional study design was conducted between January 2019 and February 2019. Masvingo province was purposively selected due to its low vaccination coverage (60.3%) according to the Zimbabwe Demographic and Health Survey 2015. WHO cluster sampling was used to select households. A total of 354 children and their mothers residing in Masvingo district were recruited for the study. Pre-tested interviewer-administered questionnaires were used to collect data. Bivariate analysis was employed to assess factors associated with low vaccination coverage. Results: An estimated 89.5% of children aged 12-23 months were fully vaccinated by card or mothers’ recall. Factors significantly associated with full vaccination coverage rates (P<0.001) included birth order, distance to the nearest health facility, waiting time, place of birth, number of Antenatal care visits, possession of a vaccination card, place of residence, mother/caregiver’s highest level of education, household expenditure per month, and overall knowledge of the vaccination schedule. After controlling for all these factors, only household expenditure per month (P=0.001), having a vaccination card (P=0.047), and overall knowledge of the vaccination schedule (P=0.002) were statistically significant predictors of full vaccination coverage rates. Conclusion: Although full vaccination coverage is improving, it is still below the Global Vaccine Action Plan target. Factors associated with low full vaccination coverage include marital age, marital status, level of education, religion, household expenditure, distance to the health center, waiting time, and Antenatal Care and Post-natal Care care utilization. There is no single factor solely responsible for low vaccination coverage; rather, it is influenced by a combination of multiple factors. Nursing interventions at community level should focus on increasing community mobilization strategies that foster saturation coverage to achieve herd immunity for all vaccine preventable child diseases.
