A-One Health Approach on the Evaluation of COVID-19 Risk Perception and Factors Associated with the COVID-19 Vaccine Acceptance in Nigeria, West Africa

Résumé

Abstract Background Effective elimination of the COVID-19 pandemic is dependent on the COVID-19 vaccines that are readily available and acceptable to the public. This study evaluated the COVID-19 risk perception and factors associated with COVID-19 vaccine acceptance in Nigeria. Methods A cross-sectional online survey with a structured questionnaire employing a Snowball sampling method was administered among Nigerian adults from the beginning of COVID-19 mass vaccination in March 2021 till December 2021. Data collected were analysed using descriptive statistics, Chi-square and multivariable regression. Participants’ general knowledge regarding COVID-19, willingness to accept COVID-19 vaccines, perception of seriousness, susceptibility of COVID-19 were assessed. Results From the 402 responses received, the mean age of the respondents was 35.1 ± 11.9 years, with the majority being males (288 (71.6%)) and non-health workers (349 (86.8%)). Overall, COVID-19 knowledge was good, with a mean score of 6.2 ± 0.19 (range 0–8) and a COVID-19 vaccine acceptance rate of 65.67%. We found a consistent positive relationship between respondents’ COVID-19 knowledge and their willingness to accept COVID-19 vaccines. Respondents who believed that the 5G network is not the cause of COVID-19 were two times more likely to receive the COVID-19 vaccine (aOR 2.38; 95%CI 1.05–5.36; p = 0.04). Furthermore, our comparisons of respondents’ age groups and marital status revealed higher odds of being willing to accept COVID-19 vaccines among respondents who were age 50 ≥ years old (aOR 7.35; 95% CI: 1.69–31.93; p = 0.008) and those who were singles (aOR 4.39; 95% CI: 1.86–10.33; p = 0.001), respectively. However, non-healthcare workers with high income and educational status were unwilling to accept COVID-19 vaccines. Surprisingly, although 303 (75.4%) of the respondents believed COVID-19 is a severe disease, only 119 (45.1%) are confident of contracting the COVID-19 should they fail to adhere to infection prevention and control (IPC) measures. Conclusion the study revealed that the intention to receive the COVID-19 vaccine varied across demographic characteristics, level of education, income and employment status, and perceived severity and susceptibility to COVID-19. We recommend continuous public health education on the risk of COVID-19 and the vital role vaccine will play in ending this pandemic.
