Mitigating Vaccine Disparities Through Faith-Based Intervention: A Pre-Post Analysis of Recombinant Zoster Vaccine Knowledge and Acceptance in Socially Vulnerable Racial and Ethnic Minoritized Communities.
Article in Infectious diseases and therapy, 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
introductionThe incidence of herpes zoster (HZ) is increasing globally. Despite the availability of a highly effective recombinant zoster vaccine (RZV), vaccination rates are still low in the United States, especially among racially and ethnically minoritized (REM) and socially vulnerable groups. There is an urgent need to identify obstacles to vaccination in these communities and develop effective strategies to increase confidence in the RZV.
methodsFrom August 2024 to December 2024, we conducted a community-based educational intervention in San Bernardino County, California, partnering with five churches in neighborhoods with high Centers for Disease Control and Prevention (CDC) Social Vulnerability Index scores. The intervention included a 45-min presentation on HZ, its complications, and RZV recommendations. Participants aged 18 + completed pre- and post-surveys to assess attitudes, knowledge, and behaviors. Descriptive statistics summarized outcomes, while a two-proportion Z-test and Fisher's exact test evaluated changes in vaccine literacy.
resultsA total of 156 individuals completed the pre-intervention survey, and 134 completed the post-intervention survey. All identified as REM, with 99% in vulnerable neighborhoods. Sixty-three percent had at least one co-morbid illness, and 46% had received info about HZ or RZV before the session. At baseline, 57% believed they were at risk of HZ, but 75% found the education session "extremely effective" in reassessing their risk. Significant improvements in vaccine literacy, especially regarding disease and age-based recommendations, were observed, with correct responses increasing post-intervention (p < 0.05). Following the intervention, 82% reported a high likelihood of receiving RZV, and 90% a high likelihood of recommending it.
conclusionsThis study demonstrates the feasibility and acceptability of a faith-based, community-led educational intervention to address barriers to RZV uptake among vulnerable REM populations. Using trusted community infrastructure can support equitable expansion of adult immunization programs to reduce preventable HZ disparities.
