Parental attitudes, beliefs and behaviors toward childhood and COVID-19 vaccines: A countrywide survey conducted in Kazakhstan examining vaccine refusal and hesitancy

Abstract

BackgroundVaccination rates worldwide have declined in recent years. This decrease is primarily driven by vaccine hesitancy, which remains understudied in Central Asia, including Kazakhstan. Furthermore, there is great concern about parental hesitancy toward COVID-19 vaccines, as previous studies have focused on adult vaccine hesitancy. The current study was conducted by UNICEF and funded by USAID to explore the drivers of routine and COVID-19 immunization behaviors among parents and caregivers in Kazakhstan. MethodsUsing a cross-sectional methodology, researchers conducted 3081 face-to-face interviews with parents and caregivers of children aged 0–17 years across cities and villages in Kazakhstan. A tablet-based questionnaire (CAPI) was utilized, collecting participants’ data on sociodemographic characteristics, childhood and COVID-19 vaccination behaviors, and potential drivers. ResultsTotal of 239 participants (7.8%) were found to previously refuse vaccination due to their own beliefs. Stronger belief that vaccines are efficacious (AdjOR = 0.47), stronger belief that childhood vaccines are safe and danger of vaccine-preventable diseases is high (AdjOR = 0.73), firmer trust in societal factors (AdjOR = 0.77) and positive attitudes of family members toward immunization (AdjOR = 0.6) were significantly associated with parental refusal of childhood vaccines. The large proportion of respondents (N = 2,634, 85.6%) missed the COVID-19 vaccination of their child or were unwilling to get vaccinated. Stronger belief that COVID-19 vaccines are safe and efficacious (AdjsOR = 0.18), lacking important information about COVID-19 vaccines (AdjOR = 1.25) and parents being unvaccinated against COVID-19 (AdjOR = 2.3) were significant predictors of vaccine hesitancy. ConclusionThis study revealed numerous socio-demographic and behavioral factors significantly associated with parental refusal of childhood vaccines and hesitancy toward COVID-19 vaccines. Many parents not refusing vaccination possessed negative attitudes towards vaccines. Potential changes in their attitudes and beliefs of parents were observed compared to findings from pre-COVID era. Continuous monitoring of parental hesitancy, proper interventions and education of healthcare workers are suggested to reduce parental vaccine hesitancy.
