Vaccines are rarely able to offer this kind of effectiveness, though the USDA <a href=\"https:\/\/www.usda.gov\/about-usda\/news\/press-releases\/2025\/02\/26\/usda-invests-1-billion-combat-avian-flu-and-reduce-egg-prices\" target=\"_blank\" rel=\"nofollow noopener\">said<\/a> last month it would step up investments in &#8220;potential new generation vaccines&#8221; with better protection.<\/p>\n<p>Kennedy&#8217;s remarks mark a sharp turn from the Biden administration, multiple former officials said.\u00a0<\/p>\n<p>Biden officials from the health and agriculture departments had wrestled extensively with calls to roll out vaccines for animals as <span class=\"link\"><a href=\"https:\/\/www.cbsnews.com\/news\/as-bird-flu-ravages-poultry-industry-the-damage-spreads\/\" target=\"_blank\" data-invalid-url-rewritten-http=\"\">outbreaks mounted on farms<\/a><\/span> nationwide. It was concerns from agriculture officials, not human health officials, that ultimately blocked plans to roll out vaccines.<\/p>\n<p>&#8220;At no point did they express a concern or anything other than robust support for an animal vaccination program,&#8221; one former USDA official said of the health agencies.<\/p>\n<p>At the time, Biden-era health officials viewed the ultimate decision as one outside of their expertise and better left to agriculture department experts, two people familiar with the planning said.\u00a0<\/p>\n<h2>Would vaccinating poultry turn birds into &#8220;mutant factories&#8221;?<\/h2>\n<p>Kennedy said the new opposition from his health agencies was based on concerns that vaccinating poultry without being able to provide sterilizing immunity would amount to &#8220;turning those birds into mutant factories,&#8221; resulting in worrying genetic changes to the virus.<\/p>\n<p>&#8220;That could actually accelerate the jump to human beings,&#8221; Kennedy said.<\/p>\n<p>Experts say vaccination would need to be managed with strict biosecurity measures \u2014 extra precautions to prevent vaccinated birds from becoming infected \u2014 to reduce the risk of genetic changes in the virus.<\/p>\n<p>&#8220;Creating conditions where the virus can freely mutate increases the likelihood of a strain emerging that can infect humans,&#8221; said Daniel Perez, chair in poultry medicine at the University of Georgia, in an email.<\/p>\n<p>Perez said the risk is higher in large-scale poultry operations, where birds can have weaker immune systems.\u00a0<\/p>\n<p>But he added that he sees vaccination as a strategic option to curb outbreaks for egg-laying chickens and backyard poultry, alongside other measures like intensive surveillance to detect outbreaks and continued culling of infected flocks of chickens raised for meat.<\/p>\n<p>&#8220;Vaccination can be a useful tool when combined with strict biosecurity. If birds are kept from exposure to the virus, then vaccination can help to contain outbreaks,&#8221; said Perez.<\/p>\n<p>Instead, Perez warned that <span class=\"link\"><a href=\"https:\/\/www.cbsnews.com\/news\/bird-flu-us-officials-walk-back-plans-to-stop-culling-poultry\/\" data-invalid-url-rewritten-http=\"\">another idea<\/a><\/span> floated by Trump administration officials could pose a far greater risk: relying on immunity from poultry surviving bird flu infections.<\/p>\n<p>&#8220;We&#8217;ve in fact said, at the USDA, that they should consider maybe the possibility of letting it run through the flock so that we can identify the birds and preserve the birds that are immune to it,&#8221; Kennedy had said.<\/p>\n<p>Perez said this approach would make surviving birds breeding grounds for worrying mutations.<\/p>\n<p>&#8220;This implies a potentially dangerous misunderstanding of how avian influenza works. Allowing highly pathogenic avian influenza to spread through a poultry flock is extremely risky and counterproductive,&#8221; he said.<\/p>\n<p>The Biden administration opted against vaccinating poultry for different reasons, former officials said.<\/p>\n<p>Agriculture officials had worried it could lead to missed spread of the virus through asymptomatic birds, trigger bans on imports of U.S. poultry products and be logistically challenging to thoroughly administer to massive commercial flocks.<\/p>\n<p>Kennedy&#8217;s comments come days after the Centers for Disease Control and Prevention <a href=\"https:\/\/www.cdc.gov\/cfa-qualitative-assessments\/php\/data-research\/h5-risk-assessment.html\" target=\"_blank\" rel=\"nofollow noopener\">released<\/a> an updated assessment of the virus, finding that the risk remains &#8220;low&#8221; to the general population but higher for people like farm workers or veterinarians who might be exposed to infected animals or contaminated surfaces.<\/p>\n<p>Most confirmed bird flu cases in humans to date have been largely mild, except for a <span class=\"link\"><a href=\"https:\/\/www.cbsnews.com\/news\/us-bird-flu-hospitalizations-rise-ohio-discloses-case\/\" target=\"_blank\" data-invalid-url-rewritten-http=\"\">handful of hospitalizations<\/a><\/span> and <span class=\"link\"><a href=\"https:\/\/www.cbsnews.com\/news\/bird-flu-h5n1-death-first-us-louisiana\/\" target=\"_blank\" data-invalid-url-rewritten-http=\"\">one death<\/a><\/span>.\u00a0<\/p>\n<p>The CDC stressed that its assessment of the risk, while low at this time, &#8220;could change, as influenza A viruses can mutate quickly, and therefore have the potential to cause pandemics.&#8221;<\/p>\n<p>    <!-- data-recirc-source=\"queryly\" --><\/p>\n<aside class=\"component list recirculation component--type-recirculation \"\/><!-- tags --><\/p>\n<div class=\"content-author\">\n      <a href=\"https:\/\/www.cbsnews.com\/team\/alexander-tin\/\" class=\"content-author__name\" data-invalid-url-rewritten-http=\"\">Alexander Tin<\/a><\/p>\n<div class=\"content-author__bio\">\n<div class=\"content-author__full-information\">\n<p class=\"content-author__text\">Alexander Tin is a digital reporter for CBS News based in the Washington, D.C. bureau.
