Simultaneous vaccination against influenza and respiratory syncytial virus in high-risk heart failure patients.
Trial report in ESC heart failure, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundThere is a scarcity of prospective data on the impact of available vaccinations against respiratory viruses on hard clinical endpoints in patients with heart failure (HF).
aimsWe investigated whether, in the population of high-risk HF patients, simultaneous vaccination against influenza and respiratory syncytial virus (RSV) improves outcomes during the subsequent infection season.
methodsWe conducted a prospective, randomized, single-centre, open-label study in which patients with high-risk HF were randomized 1:1 to simultaneous influenza and RSV vaccination or standard of care (SOC). The primary composite endpoint comprised all-cause death, HF hospitalization (HFH) or clinical signs/symptoms of infection within a 6 month follow-up period (regular structured telephone interview). Secondary endpoints were components of the composite primary endpoint.
resultsTwo hundred twenty patients were randomized. During the follow-up period, the primary endpoint occurred in 59% of patients in the vaccination group versus 75% in the SOC group [hazard ratio (HR) 0.66, 95% confidence interval (CI) 0.48-0.92, P = 0.01]. Regarding the secondary endpoint analyses, during 6 month follow-up, 3% in the vaccination group died compared with 5% of patients in the SOC arm (HR 0.50, 95% CI 0.12 1.99, P = 0.32), and 18% versus 16% of study participants were hospitalized for HF in the two study arms, respectively (HR 0.86, 95% CI 0.45-1.62, P = 0.64). Infection occurred in 53% of vaccinated patients compared with 68% in SOC (HR 0.68, 95% CI 0.48-0.96, P = 0.03).
conclusionsIn the population of high-risk HF, simultaneous vaccination against influenza and RSV reduced the incidence of the primary outcome. The effect was driven by a significant reduction in infections.
