Public Health Initiative Expands Vaccine Access
In a first for France, health authorities are extending leptospirosis vaccination beyond at-risk professions to the general population of Réunion Island. This expansion prioritizes individuals frequently exposed to freshwater environments and agricultural settings,activities identified as posing a higher risk of infection. Previously, the vaccine was primarily offered through occupational health services to farmers, horticultural workers, and agricultural employees.
The vaccination schedule involves an initial series of two injections administered two weeks apart, followed by a booster dose between four and six months later. Continued exposure necessitates revaccination every two years. This preventative measure complements existing safety recommendations, such as wearing protective clothing like gloves and boots, properly covering wounds, and maintaining equipment.
Rising Cases Prompt Urgent Response
The decision to broaden vaccine access follows a significant increase in leptospirosis cases on Réunion Island. Since the beginning of 2025, coinciding with the impact of Cyclone Garance and subsequent heavy rainfall, 114 cases have been identified. Data from the Regional Health Agency (ARS) indicates that 66% of patients required hospitalization, with approximately one-third needing intensive care.
Leptospirosis was officially added to the list of mandatory reporting conditions in August 2023, reflecting the growing concern surrounding the disease. While the illness predominantly affects men, it can impact individuals of all ages.
Vaccination Availability and Funding
Residents seeking vaccination can access services through occupational health facilities for agricultural workers, or schedule appointments at vaccination centers within the University Hospital Centers (CHU) of Saint-Denis and Saint-Pierre. The campaign is fully funded by health insurance and the agricultural social mutual fund through the social action funds of the general Social Security Fund (CGSS).
Understanding Leptospirosis and Seeking Medical Attention
Leptospirosis is a bacterial infection that can lead to severe complications and, if left untreated, can be fatal. Health authorities emphasize the importance of promptly consulting a physician if experiencing a sudden fever, muscle pain, headache, or digestive issues within three weeks of engaging in activities that may expose you to the bacteria.
