About this trial

AMBU-VAX is a prospective, single-center observational study designed to develop and implement an organizational model for delivering recommended vaccinations within a hospital setting.

The study targets adult and elderly patients with chronic diseases or immunocompromising conditions who are eligible for vaccination according to national immunization guidelines. Vaccination is actively proposed during outpatient visits, hospital admissions, or at discharge and, when accepted, administered within the hospital or coordinated with local public health vaccination services.

The study aims to evaluate the feasibility, uptake, and completion of hospital-based vaccination pathways and to support integration between hospital and territorial prevention services for vulnerable populations.
