A Unique Oral Vaccine

       In the wake of a devastating epidemic of Porcine Epidemic Diarrhea virus (PEDv) a couple of years ago, swine producers are now successfully using a not so new technique to build immunity in their herds.  They are deliberately exposing swine to the virus by adding the remains of infected baby pigs to the feed. 


      While distasteful to some, this mild exposure of the healthy animals results in a specific, long lasting immunity and is actually a pretty good way to stimulate immunity and lower the risk of future outbreaks.

       Many view this practice as new and innovative but the concept is based on the principle that exposure builds immunity - an idea originally promulgated in the 1800’s by early scientists such as Edward Jenner, Louis Pasteur, Robert Koch and Rudolf Virchow.
