Abstract
Immunization is the most cost-effective health intervention in the world yet, vaccination uptake is still low with less than 50% of children aged 12-23 months fully vaccinated Cameroon. The objective of this study was to estimate the burden of vaccine hesitancy associated with routine EPI vaccines in Yaounde-Cameroon. A two-stage cross-sectional cluster survey was conducted in Yaoundé in May-June 2022, targeting parents/guardians of children 0-59 months. Clusters were selected with probability proportionate to size (PPS) and household’s selection done using a restricted sampling method. Data collection was done using an interviewer-administered questionnaire. Data were cleaned using MS-Excel 2019, and analyzed with R version 4.1.0 (2021-05-18). A total of 529 participants were enrolled out of 708 visited, giving a non-response rate of 25%. In total, vaccine hesitancy was reported in 137(25.90[22.35-29.80] %), and vaccine hesitancy prevalence did not vary significantly across different households’ wealth levels (p-value= 0.3786). However, in wealthy households’ refusal of vaccines (14%) was less than in poorer households (20%). Lack of trust, confidence, and perceived complacency are the leading causes of vaccine hesitancy related to routine immunization in Yaounde-Cameroon. We, therefore, recommend that the burden of vaccine hesitancy should be assessed at national scale and identify sources of misinformation that are at the origin of vaccine hesitancy. Having a clear notion of the effect of social media(Facebook, Instagram, WhatsApp, etc,), radio, TV, and other information sources might guide interventions to combat vaccine hesitancy.
