The aim of this project is to highlight whether dedicated funding for vaccine procurement in healthcare institutions can generate both individual and collective benefits in terms of improved vaccination coverage among vulnerable patients at infectious risk. Should the data analysis demonstrate a positive impact on vaccination coverage among patients who attended outpatient consultations in the participating institutions during the study period, it is planned to approach the Directorate General for Health with a view to generalizing such agreements between healthcare institutions and local health insurance organizations, thereby enabling reimbursement of vaccines included in the national immunization schedule administered within these institutions. Primary objective: To assess the impact of National Health Insurance (NHI) funding for vaccines made available in outpatient consultations on pertussis vaccination coverage among pregnant women and pneumococcal vaccination coverage among eligible patients, in accordance with current French recommendations and fully covered by NHI, across four healthcare institutions in the Île-de-France region. Secondary objectives: To evaluate: * The influence of socio-economic determinants on patients' vaccination coverage; * Changes in the practices of hospital healthcare professionals in outpatient consultations regarding the monitoring of their patients' vaccination status; * Changes in practices related to the documentation of patient vaccinations to facilitate communication between healthcare institutions and primary care practitioners through the use of existing digital tools (hospital software, electronic vaccination record (CVE) in MonEspaceSanté).
