Influenza and COVID-19 vaccination in Canadian blood donors: A comparison across pre- and post-pandemic periods.
Article in Vox sanguinis, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
BACKGROUND AND
objectivesSeasonal vaccinations reduce donor illness and appointment cancellations and ensure plasma products have antibodies to vaccine-directed strains. We aimed to describe donor influenza and COVID-19 vaccination history and compare this with the general population. MATERIALS AND
methodsTwo online donor surveys were carried out in 2021 and 2024. Donors were asked about demographics, influenza (2019/2020, 2020/2021 and 2023/2024 seasons) and COVID-19 (ever and 2023/2024 season) vaccination and reasons for vaccination choices. General population vaccination statistics were extracted from public reports. Percentages of donors receiving vaccination were calculated with 95% confidence intervals. Multiple logistic regression models were fitted with demographics as independent variables.
resultsIn survey 1, 4582 (30.4% response rate) donors completed a questionnaire; in survey 2, 6376 (21% response rate). More donors under age 65 received the influenza vaccine compared with the general population under age 65 (58% vs. 30% in 2019/2020, 63% vs. 28% in 2023/2024, p < 0.0001) and aged 65+ (81% vs. 70% in 2019/2020, 90% vs. 73% in 2023/2024, p < 0.0001). Fewer donors and the general population received the COVID-19 vaccine in 2023/2024 (under 65 45% vs. 39%; 65+ 76% vs. 67%, p < 0.0001). Most said they were vaccinated to prevent infection and protect others.
conclusionSeasonal vaccination rates are higher in older donors, consistent with public health recommendations. Blood donors are more likely to be vaccinated against seasonal influenza than the general population, but post-pandemic uptake of the COVID-19 booster vaccine was low, more similar to the general population.
