Acceptance of COVID-19 vaccine and its related determinants in Nigeria: An online survey.

Background: Vaccine hesitancy is a major challenge in the fight against the coronavirus disease 2019 (COVID-19) pandemic. Identifying the sociodemographic factors associated with vaccine acceptance among Nigerians is crucial for improving vaccine uptake.

Aim: To assess the acceptance rate of COVID-19 vaccine and its related determinants among Nigerians.

Methods: An online cross-sectional survey (observational study) was conducted between February 2021 and May 2021, using a questionnaire hosted on SurveyMonkey. The invitation to take part in the poll was sent out to participants through social networking platforms. A logistic regression was used to determine which sociodemographic factors were associated with vaccine acceptance constructs.

Results: A total of 1800 persons responded to the survey, a larger proportion of whom were males (53.9%) and within the age group of 21-30 years (29.4%) and earned an average income of less than $500 per month (43.3%). Only 0.56% of participants had a high perceived risk of COVID-19 infection, while only 1.11% had a perceived risk of dying from COVID-19. The perception rate of the COVID-19 vaccine among participants was 51.1%, while the acceptance rate was 63.9%. There was no significant association between the COVID-19 vaccine acceptance rate and related determinants assessed, particularly age (χ² = 3.049, P = 0.550), sex (χ² = 0.102, P = 0.749), average income (χ² = 3.802, P = 0.875), and religion (χ² = 2.819, P = 0.420). Participants with chronic conditions demonstrated a higher acceptance rate compared to the general population.

Conclusion: Despite the positive perception observed and substantial vaccine acceptance rate among the study participants, more public health interventions are still needed to enhance vaccine acceptability in Nigeria.
