When the cattle are young, they are all vaccinated with the Covexin vaccine which protects against a series of bacterial infections such as Clostridial Myositis (Black Leg), Tetanus, and others that we can't very well pronounce. We also vaccinate them with Virashield 6 which protects against a series of common respiratory viruses, etc. We do not use any mRNA vaccine on the farm. Our Laying Hens and Broiler Chickens are vaccinated for Marek's Disease when they hatch at the hatchery. Marek's is a cancer causing form of Herpes that infects poultry. Something we'd like to avoid. So far we haven't vaccinated our pigs.
