Rate of human papillomavirus vaccination and knowledge of human papillomavirus literacy in secondary school students from Northern Thailand: post COVID-19 era.
Article in BMC public health, 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
backgroundDuring the COVID-19 pandemic, human papillomavirus (HPV) vaccination programs and media campaigns promoting HPV literacy were disrupted. As a result, many targeted students remained unvaccinated during that period. This study aimed to evaluate HPV vaccination coverage and health literacy among secondary school students in the recent post-COVID-19 era.
methodsA cross-sectional survey was conducted between July and August 2023 among 600 students (grades 7-12) from six Thai schools in Chiang Mai, a province in northern Thailand. The study assessed HPV vaccination status and HPV-related health literacy.
resultsAmong the participants (mean age 14.9 years; 47.3% female), only 21.5% (n = 120) reported receiving the HPV vaccine, with 58.3% (n = 70) completing the full course. Government supply was the primary source of vaccination, and 92.2% of vaccinated students were female. Significant differences in health literacy were observed between vaccinated and unvaccinated students, particularly in knowledge of HPV's association with cervical cancer, vaccine efficacy, safety, and perceived necessity. Differences were also evident regarding perceived cost, government promotion, awareness of national HPV policies, and the impact of the COVID-19 pandemic on vaccination uptake.
conclusionThis study highlights the persistently low HPV vaccination rate among secondary school students in northern Thailand, accompanied by notable disparities in health literacy. These findings underscore the urgent need for targeted interventions to improve awareness of HPV infection and vaccination, and to strengthen public health initiatives aimed at overcoming barriers and increasing vaccine uptake.
