Q
  1. Use of vaccination in case of confirmation of FMD
A

Vaccination
• Trade in vaccinated animals is prohibited
• Vaccinated animals from tested herds may be moved within the Member State
• A system of traceability ensures that they are excluded from Community trade

Emergency vaccination
• Classification of herds
• Animals: clearly identified and registered and must not be moved
• Specific measures in the vaccination zone to the movements of animals, fresh meat and other animal products, milk and milk products
• Clinical and serological survey

Protective vaccination
• Regionalisation of the vaccination zone
• Second surveillance zone: at least 10 km wide

Suppressive vaccination
• Part of an immediate stamping-out strategy
• Applied to ensure minimum spread of the virus during disposal of infected animals
• Carried out only within the protection zone and on clearly identified holdings
