Immunization on the French Armed Forces: Impact, organization, limits and perspectives.

Vaccination plays a key role in the prevention of the infectious diseases, which the armed forces are exposed to during overseas deployments. Historically, the French military health service have always contributed greatly to progress in vaccination. The military immunization schedule has often been used as a model for the national schedule. It is a powerful tool, which is constantly evolving to take into account the risks of infection inherent in deployment and to include new scientific data, while still remaining aware of the limitations of vaccination from an individual and collective standpoint. In the current context of increasingly fast emergence or re-emergence of pathogens with a high epidemic potential, developing preventive medical measures is more necessary than ever before, and the French military health service is actively participating.
