The FDA approved mRNA vax for beef and a different one for pork. The beef one would carry into consumers of the beef to provide covid vax to people who eat it as a way to combat vax hesitancy.
The pork one is supposed to protect hogs from swine flu, and is claimed will not transfer to humans. So since both claim contradictory info its hard to know who is lying. Both are being touted by the gates foundation. They are only legal because the us gov removed informed consent from law in 2023.
