Pan Genome Systems: Developing a novel and effective vaccine for Johne’s Disease

Webinar Description: Johne’s Disease cost the U.S. dairy industry approximately $500 million per year. Globally, the cost of the disease industry wide is several billion dollars. Currently, only 5% of U.S. dairy farmers choose to vaccinate against Johne’s Disease due, in part, to current vaccines ineffectiveness. This means that 95% of the 10 million dairy cattle on the 60,000+ dairy farms across the U.S. go untreated. Pan Genome Systems is currently developing a novel and effective vaccine which is delivered one-time in the first 30 days of life of the animal and provides a lifetime of protection. The potential global market for such a vaccine in the dairy cattle industry is estimated to be $280-360 million per year, with around $50-70 million of this in the U.S. When other ruminant animal industries that could benefit from the vaccine are included, the potential market is estimated at $500 million per year.
