Knowledge gaps and positive attitudes toward adult vaccination among nursing students: A Cross-sectional study.
Observational study in PloS one, 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
backgroundVaccination is one of the most effective public-health measures, yet adult coverage in Spain remains suboptimal due to misinformation and hesitancy. Nursing students, as future immunization promoters, play a pivotal role in vaccine recommendations. This study explored knowledge, attitudes, and recommendation practices regarding adult vaccination among undergraduate nursing students.
methodsAn observational, descriptive, cross-sectional study was conducted in the province of Alicante, Spain, between April and May 2025. An ad hoc electronic survey with 19 closed-ended items was distributed to students from the three universities offering the Nursing degree in this province; 562 students participated. Differences across academic years were analyzed using Pearson's χ² test for categorical variables and the Kruskal-Wallis test for the continuous variable age (non-normally distributed).
resultsOverall, 39.1% of nursing students were unaware of the Spanish adult vaccination schedule with significant differences across academic years (55.7% in first-year vs. 27.2% in fourth-year students; p < 0.001). Only 44.1% reported sufficient training on vaccines. Attitudes toward adult vaccination were predominantly positive: 61.4% highly favorable, 62.5% highly effective, 66.7% supporting mandatory vaccination. Additionally, 65.5% would recommend all scheduled adult vaccines. However, 47.9% perceived resistance from other healthcare professionals when recommending vaccines (p < 0.001 for the increase across academic years).
conclusionsNursing students in Alicante exhibit positive attitudes toward adult vaccination, yet significant knowledge gaps regarding the Spanish adult vaccination schedule persist even in the final year. Targeted curricular reinforcement from the first academic year is warranted within these three institutions to strengthen their role as immunization promoters.
