Knowledge, Attitudes, and Perceptions of HPV Vaccination for Adolescents with Intellectual Disabilities: A Systematic Review.
Review in Vaccines, 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/
objectivesAdolescents with intellectual disabilities may experience inequities in preventive healthcare, including HPV vaccination. This review aimed to synthesize evidence on HPV vaccination-related knowledge, attitudes and perceptions among adolescents with intellectual disabilities, parents/caregivers, educators, healthcare professionals and other stakeholders.
methodsA systematic search was conducted in PubMed, Embase and Scopus on 29 October 2025. Eligible studies reported original data on knowledge, attitudes or perceptions regarding HPV vaccination for adolescents with intellectual disabilities or relevant stakeholders. The protocol was registered on PROSPERO (CRD420251015183). Quantitative, qualitative and mixed-methods studies were considered.
resultsSeven studies were included. They were conducted in the USA, Australia and the UK and involved parents/caregivers, healthcare providers, school staff, immunization staff and adolescents or young people with disabilities. Direct evidence from adolescents was limited. HPV-related knowledge was often limited or uneven, and standard information materials were perceived as insufficiently accessible. Parents/caregivers were often broadly supportive of vaccination, but HPV-specific acceptance was affected by perceived low susceptibility, assumptions about sexual inactivity, safety concerns, procedure-related distress and lack of provider recommendation. Healthcare providers generally supported HPV vaccination; however, recommendations were sometimes influenced by perceived sexual activity, age or consent. School-based vaccination was considered useful but required tailored information, preparation, individual adjustments and follow-up.
conclusionsEvidence on HPV vaccination-related knowledge, attitudes and perceptions among adolescents with intellectual disabilities and their stakeholders remains limited and geographically restricted. Improving equitable access may require interventions that should be further investigated, such as accessible communication, systematic provider recommendation, flexible vaccination pathways and greater involvement of adolescents in decision-making.
