Safeguarding Animal Health Foot and Mouth Disease (FMD) Virus Biology Picornavirus family, Apthovirus genus 7 serotypes: A, O, C, Asia 1, SAT1, SAT2, SAT3 Multiple topotypes (substrains tied to geographical region) within each serotype

Safeguarding Animal Health APHIS FMD Response Goals 7 The goals of an FMD response are to: (1) detect, control, and contain FMD in animals as quickly as possible; (2) eradicate FMD using strategies that stabilize animal agriculture, the food supply, the economy, and protect public health and the environment; and (3) provide science- and risk-based approaches and systems to facilitate continuity of business for non- infected animals and non-contaminated animal products.
FMD Response Strategies 9 FMD response strategies—strategies are not mutually exclusive: Stamping-out Stamping-out modified with emergency vaccination to kill Stamping out modified with emergency vaccination to slaughter Stamping-out modified with emergency vaccination to live Combination of options Vaccination to live without stamping-out
Safeguarding Animal Health Challenges to Stamping-Out Only Strategies Huge herds, highly concentrated Mobility of animals/products
Safeguarding Animal Health Develop a Balanced Response Strategy
Safeguarding Animal Health Continuity of Business Planning Secure Milk Supply: for milk and milk movement in an FMD outbreak, to avoid and mitigate interruptions in movement. Secure Pork Supply: for swine and pork products, to avoid and mitigate interruptions in movement.

Safeguarding Animal Health The Complexities of FMD Vaccine Planning 7 serotypes: A, O, C, Asia 1, SAT1, SAT2, SAT3 Multiple topotypes within each serotype Topotypes within serotype ± cross-reactive Most vaccine inactivated (killed) Molecular vaccines in development (Genvec) Two categories: Emergency Vaccine - ≥ 6 PD 50 Commercial Vaccine - ≥ 3 PD 50 Emergency vaccine stored as concentrate Commercial vaccine stored as finished product Difficult to anticipate what to bank Novel vaccine technology needed
Mission Statement The NAFMDVB fosters the preparedness for responding to an FMD outbreak in North America, maintaining expertise in FMD vaccines, vaccine deployment, vaccination and other FMD control measures. The NAFMDVB maintains the repository of vaccine antigen concentrates (VAC) for the production of emergency FMD vaccines.
Background Established: In 1982 from a Memorandum of Understanding between United States, Canada, and Mexico to ensure the availability and readiness of vaccines when needed, to control an outbreak of Foot and Mouth Disease in North America. Based on emergency vaccinate to kill strategy Annual contributions from Canada, Mexico and the United States proportional to the susceptible animal population of each country.
Two Governing Bodies The Commission: Chief Veterinary Officer from each country The Technical Committee (TC): Comprised of one technical and one regulatory representative from each country. The TC advises the Commission on matters of a scientific and technical nature. The TC works in coordination with the Emergency Management Working Group (EMWG) to advise the Commission on policy and implementation of the NAFMDVB program by each member country. The EMWG is a subcommittee of the North American Animal Health committee (NAAHC) charged with coordinating, harmonizing, and expediting animal health emergency management in North America.
NAFMDVB Location USDA’s Foreign Animal Disease Diagnostic Laboratory (FADDL) at the Plum Island Animal Disease Center. Under stringent safety and security controls 24/7.
Facilities Laboratory facility for antigen, sera and master seed testing. Storage facility Liquid nitrogen freezers for antigens and antigen samples Refrigerators for pilot vaccines Access to animal rooms with capacity to house 17 bovines of 400 pounds.
