The Biden administration is considering the mass vaccination of the poultry population in response to an ongoing outbreak of avian flu that has killed off millions of birds and has helped spike egg and poultry costs.
There are some existing vaccines for farm birds, but U.S. Agriculture Department spokesman Mike Stepien told The New York Times that no vaccination effort has been authorized and the department is unsure if the existing vaccines will be effective against the current strain of H5N1 bird flu. Erica Spackman, a researcher for the USDA’s Agricultural Research Service, told the newspaper that scientists are researching new vaccine candidates to help curb the ongoing bird flu outbreak.
Thus far, the Biden administration has made no decision to impose a poultry vaccine mandate.
Instead of a bird flu vaccine program, many farmers have instead been culling millions of their livestock. At least 52.3 million birds were killed off throughout the United States in 2022.
Bird Flu Risks
Bird flu can be deadly. An 11-year-old girl in Cambodia died last month after becoming infected with H5N1.Bird flu can spread to humans through direct contact between a person and a farm bird or between a person and a contaminated surface. Bird flu contaminants can also spread through droplets or dust particles that a farm bird could kick up when it flaps its wings.
Vaccine Program Would Have Trade-Offs
Vaccinating millions of farm birds could be a complicated endeavor, and while a vaccine program may be able to slow or prevent the spread of the bird flu, it could also trigger trade bans.While a vaccine program might help farmers to prevent disease outbreaks and preserve more of their livestock and poultry products, the costs of the program might outweigh the international trade regulations a vaccine program could trigger.
Other countries are also considering a new poultry vaccine program to counteract the H5N1 bird flu.
“So it has to be carefully balanced, but obviously with the changing risk, looking at vaccination as one component of a control program is obviously prudent,” Brown added.
