Assessing the Reliability of Self-Reported Hepatitis B Vaccination Status in Outpatients: Evaluation of Individuals Born in France and Consulting at the CeGIDD in Saint-Denis.

This study aims to find out whether people accurately know their hepatitis B vaccination status. It focuses on individuals born in France who visit a sexual health clinic (CeGIDD) in Saint-Denis. During the consultation, each person is asked whether they think they are vaccinated against hepatitis B. Then, a blood test is done to check if they really are. The goal is to see how often people's answers match their actual medical status. The study also looks at factors like age, gender, education level, and whether they have a regular doctor to understand who is more likely to be unsure or mistaken about their vaccination status. About 200 participants are expected to take part.

Inclusion Criteria:

• Patients born in France.
• Consulting at the CeGIDD of Delafontaine Hospital in Saint-Denis.
• Requiring a hepatitis B serology test.

Exclusion Criteria:

- Patients with a history of past hepatitis B infection.
