Pigs and cows are being given the mRNA shots since 2018. What? Before the whole COVID hysteria.

Some animals, like ones at zoos, have been given a COVID vaccine, but it's not the same one that's given to people, and it doesn't use mRNA. That being said, there are a number of vaccines for animals that use RNA platforms, and that's been the case for many years. Owners have discretion over which vaccines they want to give or not give their livestock, and there's currently no mRNA vaccines that are licensed for use on animals.
