Impact of the COVID-19 pandemic on influenza vaccination coverage in Latin America: Southern Cone, Argentina, Chile, and Uruguay.
Article in Revista panamericana de salud publica = Pan American journal of public health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Objective: Analyze the impact of the COVID-19 pandemic on influenza vaccination coverage in some countries in the Americas. Methods: This descriptive ecological study included Argentina, Chile, and Uruguay and analyzed information on influenza vaccination coverage in the countries during 2018-2023. The study reports annual estimates of influenza vaccination coverage expressed as a percentage of the population. The sources used were those reported by the Pan American Health Organization/World Health Organization and the ministries of health of the countries studied. Results: Comparatively, vaccination coverage rates according to risk groups among Argentina, Chile, and Uruguay show a downward trend without reaching optimal vaccination coverage for 2018 to 2023. Increased vaccination rates were reported in 2020 for all age and risk groups, except in Uruguay for children under 5 years of age. Among pregnant women, Argentina reported higher coverage in 2020 with 77%, Chile 90% (2018), and Uruguay 55% (2020). Among health workers, all three countries reached their highest coverage in 2020 (100%) but reported a decrease for 2022. Conclusion: The studied countries have observed a decrease in post-COVID-19 influenza vaccination coverage. Therefore, they are working to achieve optimal coverage, not only in influenza risk groups but across the entire population. Data on influenza vaccination coverage are limited in some cases. The availability of new vaccines can provide greater immunogenicity, efficacy, and effectiveness. However, they represent a challenge for the Expanded Program on Immunization, which requires cost-effectiveness studies to evaluate new vaccines while experiencing restricted national budgets.
