RFK Jr. warns vaccinating poultry for bird flu could backfire

Federal health agencies oppose the use of bird flu vaccines in poultry right now, Health and Human Services Secretary Robert F. Kennedy Jr. said, weighing in publicly on it for the first time in his new role. The Trump administration has been considering poultry vaccination as it seeks to combat the outbreak that is fueling a record surge in egg prices.

U.S. Department of Agriculture officials said last month that they were ramping up planning on potentially deploying a vaccine for poultry, with the hopes of putting a draft of the plan before trading partners "as quickly as possible," since it could affect billions of dollars in exports.

"There's no indication that those vaccines actually provide sterilizing immunity and all three of my health agencies, NIH, CDC, and FDA, the acting heads of those agencies have all recommended against the use of the bird flu vaccine," Kennedy said in an interview on Fox News published this week.
