HPV Vaccine Uptake, Hesitancy and Information Sources Among Young Adults: A Cross-Sectional Study of Korea and the US.
Article in Health science reports, 2026. 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
Background and Aims: Despite the high effectiveness of HPV vaccination, uptake among young adults remains suboptimal. Healthcare policies, vaccine hesitancy, and sources of vaccine information may contribute to differences in vaccination behaviors across countries. To examine cross-national and sex-specific differences in HPV vaccine uptake and hesitancy among undergraduates in the US and Korea, and investigate the role of information sources. Methods: This cross-sectional study targeted undergraduate students in the US and Korea aged between 18 and 25. Data was collected from August 29, 2023, to February 20, 2024 using an online survey through social media exclusive to college students (Korea) and a university listserv (US). A total of 224 survey responses were analyzed after removing missing data ( Results: HPV vaccine uptake was substantially higher in the US than in Korea (74.0% vs. 33.1%), with a significant sex gap observed only in Korea. Although no significant cross-national differences in HPV vaccine hesitancy were observed, sex-specific patterns emerged within each country (OR = 5.3; 95% CI = 1.1-25.3; Conclusions: Tailored public health strategies that address social media's potential role in shaping HPV vaccine hesitancy, while expanded policy support in Korea could improve uptake and reduce hesitancy.
