Assessing COVID-19 Vaccination Uptake and Incident Infections Among Ethiopian Healthcare Workers, Addis Ababa-2022: Implications for Public Health Preparedness.
Article in Clinical infectious diseases : an official publication of the Infectious Diseases Society of America, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe coronavirus disease 2019 (COVID-19) pandemic exposed global public health preparedness challenges. In Ethiopia, healthcare workers (HCWs) faced barriers to vaccination despite widespread availability. Here, we describe severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections and vaccine uptake among HCWs in Addis Ababa after the national vaccine rollout.
methodsA prospective cohort study enrolled 469 HCWs with baseline and 5 follow-up visits over 6 months (January 2022-July 2022). Nasopharyngeal swabs were tested using real-time reverse transcription polymerase chain reaction. Associations among participant characteristics, vaccination status, and SARS-CoV-2 infection were assessed using the Fisher exact test and odds ratios (ORs) with 95% confidence intervals (CIs).
resultsAt baseline, 57% (267 of 469) of participants were fully vaccinated, with physicians having higher uptake than other HCWs (82% vs 52%; P < .001). Vaccination was not associated with perceived risk (P = 1.00) or workplace exposure (P = .08). Over 6 months, 11% (53 of 469) experienced SARS-CoV-2 infection, all with mild symptoms and no hospitalizations. Infection was not associated with vaccination (P = .66) or occupational characteristics but was more likely in HCWs who felt safe from infection (OR = 2.05; 95% CI, 1.11-3.81; P = .02).
conclusionsDespite vaccine availability, uptake remained suboptimal among Ethiopian HCWs. Misalignment between perceived risk and vaccination decisions suggests the need for targeted interventions. Educational campaigns and community leader engagement may improve vaccine acceptance. The association between perceived safety and infection risk highlights the need for continued infection prevention measures.
