Perceptions and predictors of COVID-19 vaccine hesitancy among healthcare providers across five countries in sub-Saharan Africa.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The African continent has some of the world's lowest COVID-19 vaccination rates. While the limited availability of vaccines is a contributing factor, COVID-19 vaccine hesitancy among healthcare providers (HCP) is another factor that could adversely affect efforts to control infections on the continent. We sought to understand the extent of COVID-19 vaccine hesitancy among HCP, and its contributing factors in Africa. We evaluated COVID-19 vaccine hesitancy among 1,499 HCP enrolled in a cross-sectional study conducted as a telephone survey in Burkina Faso, Ethiopia, Nigeria, Tanzania, and Ghana between July to December of 2021. We defined COVID-19 vaccine hesitancy among HCP as self-reported responses of definitely not, maybe, unsure, or undecided on whether to get the COVID-19 vaccine, compared to definitely getting the vaccine. We used log-binomial or modified Poisson regression models to evaluate factors influencing vaccine hesitancy among HCP. Approximately 65.6% of the HCP interviewed were nurses and the mean age (±SD) of participants was 35.8 (±9.7) years. At least 67% of the HCP reported being vaccinated. COVID-19 vaccine hesitancy affected 45.7% of the HCP in Burkina Faso, 25.7% in Tanzania, 9.8% in Ethiopia, 9% in Ghana and 8.1% in Nigeria. Among unvaccinated HCP reasons for low vaccine uptake included concern about vaccine effectiveness, side effects, and fear of receiving experimental and unsafe vaccines. HCP reporting that COVID-19 vaccines are very effective (RR: 0.21, 95% CI: 0.08, 0.55), and older HCP (45 or older vs.20-29 years, RR: 0.65, 95% CI: 0.44, 0.95) were less likely to be vaccine-hesitant. Nurses were more likely to be vaccine-hesitant (RR 1.38, 95% CI: 1.01, 1.89) than doctors. Information asymmetry among HCP, beliefs about vaccine effectiveness, and the endorsement of vaccines by public health institutions may be important. Efforts to address hesitancy should consider information and knowledge gaps among different cadres of HCP alongside efforts to increase vaccine supply.
