Factors related to vaccine hesitancy during the implementation of Measles-Rubella campaign 2017 in rural Puducherry-A mixed-method study

Abstract

Background: Measles is one the leading cause of morbidity, mortality, and disability among under-five children worldwide with India contributing to half of the burden. Hence, Measles-Rubella (MR) campaign was launched to vaccinate all the children between 9 months and 15 years. The current study was done to find the prevalence and factors related to vaccine hesitancy in the MR campaign 2017 in rural Puducherry. Methods: This was a mixed-method study conducted with a quantitative part involving cross-sectional survey done among parents of children aged between 9 months and 15 years to determine the proportion of MR vaccine hesitancy and qualitative part involved in-depth interviews to explore the barriers and facilitating factors for the MR vaccine hesitancy. Results: Among 461 participants, the prevalence of vaccine hesitancy for the MR campaign was 14.1% (95%CI: 11–17.6%). In adjusted analysis, only mother's age (aPR–2.27) was the significant predictor of vaccine hesitancy. In qualitative analysis, major facilitating factor for campaign was the role played by the doctors in spreading awareness regarding the importance of vaccine and trust by parents on doctors. Major hindering factors were inadequate knowledge regarding campaign, rumors spread about the safety of vaccine, sudden planning, and under preparedness at health system level. Conclusion: The current study found that almost one-fifth of the parents were hesitant to give vaccination to children. Social media rumors, lack of knowledge among parents, and inadequate time in planning were major reasons for vaccine hesitancy. Hence, countries should undertake training and education of healthcare workers to empower them to address the vaccine hesitancy.
