Historical situation • South Korea historically "FMD free w/o vaccination " • Increased frequency of FMD incursions from neighbouring, endemic
countries over past decade • Stamping out policy, average direct cost ~ US$165M per incursion
before restoration of "FMD free" status
• January 2011: decision to change
control policy into vaccination of the whole susceptible animal population (10M pigs, 3M cattle), culling only unvaccinated animals in new outbreaks.
• Change of country status to "endemic with vaccination".
Case study – The South Korea Outbreak
November 2010 outbreak Unprecedented magnitude Culling of ~3.5 million animals (3.3M pigs /140K cattle)

Mass culling and burial of pigs in Korea (Nov. 2010 – Feb. 11)
- Direct costs (3.3 millions pigs + 140 000 cattle): $2 Bn - Total costs: ~$8 Bn

• Antigen banks are stocks of immunogenic materials ready to be
formulated into vaccines in case of introduction into FMD-free country
• FMD virus antigen are highly concentrated and stored over liquid N2 (-
