Vaccine refusal and hesitancy in Spain: an online cross-sectional questionnaire.
Observational study in BMC primary care, 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
backgroundVaccine refusal and hesitancy represent a crucial challenge to public health, causing delays in vaccination and compromising herd immunity.
methodsTo address this issue, we conducted a comprehensive observational study on the adult Spanish population in 2021. Using an online questionnaire, we examined the sociodemographic and sociocultural factors, beliefs, and opinions of those refusing or hesitant about vaccines, as well as their vaccination behaviors by vaccine type and sex.
resultsThere were 1,312 respondents: 74.5% were female, 73.7% were between 31 and 59 years old, and 71.0% had university studies. Our findings revealed that vaccine refusal rates were relatively low (16.8%), and mainly associated with influenza vaccination (10.3%). Higher refusal rates were observed in those over 60 years old, those expressing hesitancy due to vaccine components, those opposing free and compulsory vaccination, those unaware that vaccination protects the community, and those against consuming cow's milk and using infant formulas for breastfeeding. Vaccine hesitancy was greatest in individuals under 31 years old, women, parents of children under 15 years old, against compulsory vaccination, unaware that vaccination protects the community, with hesitancy due to vaccine costs, and in favour of alternative and complementary treatments.
conclusionsThese insights highlight the need for strategies to improve education about vaccination and dispel misconceptions, which are crucial for effectively reducing vaccine refusal and hesitancy across the population.
