In Italy, free vaccinations for Herpes Zoster (HZ), pneumococcal (PCV), and influenza (FLU) are recommended each year for individuals turning 65. Despite this, achieving optimal vaccination coverage remains challenging. This study assesses coverage rates for HZ, PCV, and FLU in Forlì, Northern Italy, and examines how altitude, urban planning, and health organization variables (such as the presence of a vaccination center) impact vaccine uptake. Vaccination coverages were calculated for birth cohorts between 1952 and 1958 for each municipality in the Forlì area as of 1 March 2024. The geographical factors influencing the vaccination uptake were extracted from the Italian National Institute of Statistics (ISTAT) records and evaluated through a multivariate analysis. The sample analyzed included 15,272 vaccine campaign targets from Forlì’s province (185,525 citizens); the vaccine uptake rates for HZ, PCV, and FLU were 26.9%, 36.7%, and 43.5%, respectively. Gender did not appear to influence vaccine uptake. Living in a flat area appeared to increase vaccine uptake in a statistically significant way for all the vaccinations when compared to a mountainous area (HZ: OR: 1.50, PCV: OR: 1.33, FLU: OR: 1.67). The presence of a vaccine service in low-urbanized areas was shown to increase vaccine uptake for all vaccinations (HZ: OR: 1.65, PCV: OR: 1.93, FLU: OR: 1.53) compared with low-urbanized areas without a vaccination center or more urbanized areas with a vaccination center. This study emphasizes the significance of the territorial context, along with the ease of access to vaccinations and geographic barriers, as key determinants in achieving vaccination targets. Local health authorities should consider these factors when implementing vaccination campaigns.

Background/Objectives: Vaccinations are a cost-effective strategy to reduce morbidity and mortality from infectious diseases, particularly in individuals with diabetes mellitus (DM). Despite recommendations for routine vaccination, uptake among adults with DM remains suboptimal. This study evaluates the effectiveness of interventions aimed at increasing Herpes Zoster (HZ) vaccine coverage in diabetic patients. Methods: This study included diabetic patients residing in the Romagna Local Health Authority (1.2 million inhabitants). Two complementary strategies were implemented: patient-oriented interventions (reminders/recalls) and provider-focused actions to engage general practitioners and diabetologists. Vaccination coverage in December 2023 was compared with December 2024, stratified by age, sex, and nationality. Primary outcomes were changes in coverage and intervention impact. Multivariate logistic regression assessed sociodemographic determinants of adherence. Results: As of 31 December 2023, 5182 diabetic patients had received at least one dose of Herpes Zoster vaccine (7.4% coverage). In 2024, overall coverage (11.1%) increased across all sociodemographic groups. Coverage rose to 12.8% in males and 9.0% in females and to 11.7% among Italian citizens, while foreign citizens showed lower absolute levels but a greater proportional increase. By age, individuals born after 1958 exhibited the largest relative growth, whereas those born in 1952–1958 reached the highest absolute coverage in 2024. Male sex, the 1952–1958 birth cohort, and Italian citizenship were associated with a higher likelihood of vaccination in both years. Conclusions: Our findings show a positive trend in Herpes Zoster vaccination among diabetic patients in Romagna HLA, driven by patient reminders, provider engagement, and age-targeted campaigns, while persistent sociodemographic disparities underscore the need for tailored strategies to optimize coverage.
