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

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.

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

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.

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.

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.
