We assessed perceived vaccination knowledge, attitudes, self-reported vaccine receipt, and variation by age, sex, region, and delivery pathway among digitally connected patients with HF enrolled in a nationwide telemonitoring program. Methods: This cross-sectional electronic survey was conducted from 5 to 28 November 2025, during the ongoing 2025\u20132026 influenza and COVID-19 vaccination campaigns, among app-connected Satelia\u00ae Cardio participants across France. Of 4856 invited app-connected patients, 1100 completed the questionnaire (response rate: 22.7%). Uptake of seasonal influenza and COVID-19 booster vaccination for the 2025\u20132026 season and lifetime receipt of pneumococcal, tetanus\u2013diphtheria\u2013pertussis\u2013poliomyelitis (Tdap-polio), and herpes zoster vaccines were analyzed using Wilson 95% confidence intervals (CIs), age-adjusted logistic regression, and regional models adjusted for age and sex. Results: Respondents had a mean age of 71.5 years (SD: 12.6), and 718 (65.3%) were men. Overall, 87.5% considered vaccination useful, 96.0% knew where to be vaccinated, and 55.1% wanted telemonitoring-based reminders. Current-season reported vaccination was 62.2% for influenza and 31.4% for the COVID-19 booster, whereas lifetime self-reported receipt was 38.5% for Tdap-polio, 34.5% for pneumococcal vaccination, and 11.5% for herpes zoster. Influenza and COVID-19 uptake increased with age, whereas pneumococcal uptake peaked at 65\u201374 years. Pneumococcal receipt was higher in women than men (42.2% vs. 30.4%; age-adjusted odds ratio [aOR], 1.67; 95% confidence interval [CI], 1.29\u20132.17; p &lt; 0.001). Community pharmacies delivered most influenza and COVID-19 vaccinations. Conclusions: Vaccination attitudes were favorable, while current-season vaccination and lifetime-reported vaccine receipt showed distinct patterns across age groups. These descriptive findings identify potential target groups for future telemonitoring-based preventive interventions, whose effectiveness requires prospective evaluation.<\/jats:p>","DOI":"10.3390\/jcm15176933","type":"journal-article","created":{"date-parts":[[2026,9,7]],"date-time":"2026-09-07T16:30:02Z","timestamp":1788798602000},"page":"6933","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Perceived
