Acceptance of COVID-19 vaccine among healthcare workers in Katsina state, Northwest Nigeria

High acceptance of COVID-19 vaccines is crucial to ending the COVID-19 pandemic. Healthcare workers (HCWs) are frontline responders in the fight against COVID-19, they were prioritized to receive the COVID-19 vaccine in Nigeria. This study assessed the acceptance of the COVID-19 vaccine among HCWs in Katsina State using an online structured questionnaire and predicted variables that could increase the acceptance of the vaccine among HCWs using logistic regression analysis. A total of 793 HCWs were included in this study. Of these, 65.4% (n=519) of them were male and 36.2% (n=287) were aged between 30-39 years. Eighty percent (80%, n=638) of the HCWs have been tested for the SARS-CoV-2 out of which 10.8% (n=65) of them tested positive. The majority of the HCWs (97.3%, n=765) believed that the COVID-19 vaccine was safe and 90% (n=714) of the HCWs have received the first dose of the COVID-19 vaccine. Our findings showed that the age of the HCW, their COVID-19 testing status, and the type of health facility they work (either public or private) were the main predictors for the acceptance of the COVID-19 vaccine among HCWs in Katsina state. HCWs between the age of 30-39 years were more likely (OR:7.06; 95% CI: 2.36, 21.07; p < 0.001) to accept the vaccine than others. In the same vein, HCWs that have been tested for COVID-19 were more likely (OR:7.64; 95% CI: 3.62, 16.16; p < 0.001) to accept the vaccine than those that have not been tested. In addition, HCWs in public health facilities were more likely (OR: 2.91; 95% CI: 1.17, 6.11; p = 0.094) to accept the COVID-19 vaccine than their counterparts in private health facilities. There was a high acceptance of the COVID-19 vaccines among HCWs in Katsina State. More emphasis should be paid on adherence to non-pharmaceutical interventions and the availability of vaccines for HCWs in private hospitals.
