The goal of this observational study is to learn about the rate the of knowledge of own vaccination status among healthcare workers working at Groupe Hospitalier Sud Ile de France. The main question it aims to answer are : knowledge of own vaccination status is less than 50% among healthcare workers working at Groupe Hospitalier Sud Ile de France and the assessment of the relationship between healthcare workers of Groupe Hospitalier Sud Ile de France and vaccination in general.

Healthcare professionals in France are subject to a number of vaccination obligations, and following successive anti-SARS-CoV2 vaccination campaigns, these obligations are under discussion. Even healthcare professionals are reluctant to be vaccinated , particularly in view of annual vaccination rates against seasonal influenza: 22% were vaccinated against seasonal influenza in 2022, and 25.9% knew their general vaccination status.

As part of the national "European Vaccination Week" event organized by the French Ministry of Health and Prevention, we propose a questionnaire designed for hospital healthcare workers to assess their knowledge of their own vaccination status, and evaluate their attitude with vaccination.

The link to the questionnaire will be forwarded to staff e-mail addresses, and it will be administered on a one-off basis. At least 100 professionals will be surveyed. Each participant is expected to complete the questionnaire in 10 minutes, and the total duration of the research is one week.
