BackgroundThe Coronavirus diseases (COVID-19) pandemic is not abating and there is no approved treatment yet. The development of vaccines is hoped to help in addressing this disease outbreak. However, in the face of anti-vaccines uprise, it is important to understand the factors that may influence the uptake of COVID-19 vaccines as this will influence how successful the fight against COVID-19 will be in the long term.MethodsA cross-sectional study among 776 adult Nigerians (age ≥18 years) was conducted in the 36 States of Nigeria and the Capital City with online questionnaire. The questionnaire consisted of 5 sections: socio-demographic characteristics of respondents, respondent’s knowledge of COVID-19, respondents risk perception of COVID-19, vaccination history of respondents, and willingness to receive COVID-19 vaccine. Descriptive analysis of variables was done and multivariate analysis using logistic regression was carried out to determine the predictors of uptake of a potential COVID-19 vaccine. The level of significance was predetermined at a p-value < 0.05. Data analysis was done with SPSS version 21.ResultsMost of the respondents were male (58.1%). Most participants were willing to take a potential COVID-19 vaccine (58.2%), while 19.2% would not take it with 22.6% indecisive. 53.5% would prefer a single dose COVID-19 vaccine. For vaccine uptake, being male (p= 0.002) and the perception that “vaccines are good” (p< 0.001) were the positive predictor of uptake of a potential COVID-19 vaccine.ConclusionMost Nigerians were willing to take a potential COVID-19 vaccine with the male gender and perception that “vaccines are good” being positive predictors. There is a need for public enlightenment aim at encouraging those that are indecisive or averse to receiving COVID-19 vaccines.

Background: The Coronavirus Disease 2019(COVID-19) is far from over, although appreciable progress have been made to limit the devastating effects of the pandemic across the globe. Adequate knowledge and risk perception is a critical assessment that is required to ensure proper preventive measures. This study assessed these among Nigerians. Methods: The study was a cross-sectional assessment of 776 consenting Nigerian adults that were distributed across the 6 geo-political zones and the Federal Capital Territory. Online pre-tested, semi-structured questionnaire were used to obtain the socio-demographic data and assessed the knowledge and risk perception of the participants to COVID-19. The knowledge of COVID-19 was assessed based on the number of accurate responses given in comparison to average scores. Chi-square analysis was computed to analysis the association between socio-demographic characteristics and knowledge of COVID-19 and risk perception. Data analysis was done using SPSS version 21, the level of significance was set at value p<0.05 at 95% confidence interval. Results: Majority of the participants were male 451 (58.1%), there was a good knowledge of COVID-19 among 90.3% of respondents with 57% having positive risk perception. There was a statistically significant relationship between good knowledge and positive risk perception of COVID-19 (p < 0.001). Annual income (p =0.012) and the perception that vaccines are good significantly predict positive risk perception of COVID-19 among the respondents. Conclusion: A good knowledge of COVID-19 and vaccination against the virus were the two most important factors that determined risk perception among the population. This may be because of the widespread advocacy, and it portends a good omen at combating COVID-19 menace. Key words: COVID-19, Risk perception, Nigerians
