USA - American Association of Swine Veterinarians Position Statement on Pandemic (H1N1) 2009 Influenza

The emergence of the pandemic (H1N1) 2009 influenza virus has reminded us of the potential for cross-species transmission of influenza viruses. As veterinarians, we believe that protecting human health is of primary importance, and all reasonable measures should be taken to avoid any unnecessary risk to human health. The "One Health Initiative" of the American Veterinary Medical Association and the American Medical Association recognizes the impact that animals have on human health and vice versa.1 An essential component of protecting human health is providing a safe, high quality, and affordable food supply.

Influenza recommendations for pork production staff, veterinarians, and harvest plant workers
• Swine owners continue to encourage, facilitate, and financially support employee vaccination against seasonal influenza viruses.
• All personnel associated with pork production and harvest in North America be given high priority for vaccination against any novel influenza virus that emerges in the human population.
• The Centers for Disease Control and Prevention, state departments of health, and local health departments work in close cooperation with, solicit input from, and collaborate in the decision-making process with USDA-APHIS, state animal health officials, and local veterinarians through the establishment of working groups and defined communication channels to facilitate the implementation of vaccination plans across North America.
• All personnel associated with pork production and harvest intensify basic hygiene and biosecurity practices.

Influenza vaccination recommendations for swine
• Vaccination with currently approved vaccines for the control of swine influenza should continue to be used to control clinical signs of disease due to swine influenza virus as recommended on each product's label.
• Vaccination of swine against the pandemic (H1N1) 2009 influenza virus should be implemented if scientific evidence demonstrates that vaccination reduces virus shedding and the risk of transmission to pork production personnel.
• Increased funding and research on novel delivery methods and vaccines to rapidly develop and introduce safe, effective vaccines against novel influenza viruses that not only minimize the risk of transmission between species but also overcome maternal immunity.
• Increased funding and research on the utilization of technologies, such as core matrix, that would enable the rapid updating of influenza vaccines to incorporate emerging strains, promote cross-protection against multiple influenza strains and facilitate the development of a differential vaccine.

Development of a national influenza vaccine strain selection system for swine
• The development of a system modeled on the WHO system for strain selection that facilitates the production of national or regional influenza vaccines for swine.
• Increased government funding and infrastructure to support the surveillance of influenza strains of swine and the development of vaccine strategies that reduce influenza risk.
• That the Center for Veterinary Biologics (CVB) promote new technology and streamlined vaccine approval methods to enable the timeliness of market entry, given the potential frequency of influenza antigenic drift and shift.
• That universities, diagnostic laboratories, and commercial organizations release their rights to ownership of influenza genetic material for the purpose of production of a national influenza vaccination program for swine.

Swine movements in herds infected with novel type A influenza virus
• Pork producers cooperate fully and actively participate in the development and implementation of surveillance programs established by federal, state, and local governments to promote a full understanding of the extent of a novel virus spread in the US swine herd.
• Producers consult with and implement the recommendations of their veterinarian to fully understand any potential new infections in their herds, and veterinarians use the best available information to make science-based decisions on appropriate control measures for those herds.
• Movements of animals originating from infected herds are continued under the supervision of the herd veterinarian(s) in accordance with state and federal regulations (refer to USDA's H1N1 Response Guidelines)
