Poultry Vaccination Concerns Raised by HHS Director
Health and Human Services Director Robert F. Kennedy Jr. has expressed concerns about vaccinating poultry against the highly pathogenic avian influenza A (H5) virus, suggesting that it may create environments where mutant viruses could emerge, potentially affecting humans.
“All my agencies advise against bird vaccinations,” Kennedy stated. During an interview with Sean Hannity, he elaborated that using a vaccine which doesn’t ensure sterile immunity could turn flocks into “mutation factories.” This, he argued, may enable viruses to learn how to mutate, raising the chances of transmission to other animals.
Despite Kennedy’s warnings, which are echoed by agencies like the National Institutes of Health and the Centers for Disease Control and Prevention, the U.S. Department of Agriculture is seriously considering the vaccination of American poultry farms. A USDA spokesperson mentioned they are assessing the feasibility of using HPAI vaccines but clarified that no vaccine is currently permitted.
The discussion gained momentum following a spike in egg prices that hit record levels in February, prompting interest in vaccination as a potential solution. After a long period of declining prices, egg costs surged dramatically in the latter half of Biden’s presidency, reaching an all-time high of $6.22 per dozen in March.
Several factors have contributed to this surge. For starters, there’s the shift toward cage-free hens alongside record consumer demand. A significant contributor to the price increase has been the USDA’s decision to eradicate both commercial and backyard bird populations in response to the HPAI virus.
On February 8, 2022, the USDA confirmed cases of avian influenza belonging to the Clade 2.3.4.4b strain. By March 2025, the USDA instructed actions that led to the culling of over 166 million birds—reducing the number of eggs available and placing upward pressure on prices.
“Vaccinations in the poultry sector could jeopardize the entire export market of U.S. poultry products,” a spokesperson warned. Meanwhile, Agriculture Secretary Brook Rollins outlined a plan to tackle avian flu and alleviate costs for American families, proposing a financial commitment of up to $500 million for poultry growers and emphasizing enhanced biosecurity measures.
While egg prices have returned closer to normal, the USDA continues to evaluate potential vaccination options. The spokesperson clarified that before a decision is made, consultations will involve state officials, veterinarians, and farmers, as well as the public health system and citizens.
Industry members expect the USDA to develop a vaccination plan by July. However, a debate persists within the poultry industry regarding mass vaccinations. Dr. John Clifford, a former chief veterinarian for the USDA, cautioned that such vaccinations could lead importers to halt U.S. poultry imports if they suspect the vaccine is masking the presence of HPAI.
Some industry groups, however, are more welcoming to the idea. The National Chicken Council expressed concerns about the risks to the export market if vaccinations are implemented without adequate safeguards but suggested they might support the program if exports remain unaffected. In contrast, some experts argue against mass poultry vaccinations, advocating for improved biosecurity measures instead.
Overall, it remains uncertain how the USDA will proceed. While some seek immediate vaccination solutions, others warn about the potential risks of creating dangerous virus mutants through widespread vaccination.
