Harrisvaccine says it has shipped 770,000 doses of a vaccine to counter Porcine Epidemic Diarrhea virus (PED).
They have gone to hog operations in Iowa and North Carolina while the company continues to seek approval from the United States Department of Agriculture to market the vaccine on a national basis under a provisional licence for emergency response.
It can be purchased under veterinary prescription.
The disease was first noticed last spring, but has spread to hog farms in 20 states. So far there have been no cases confirmed in Canada.
Harrisvaccines, based in Ames, Iowa, says it’s too early to tell how effective its new vaccine will be.
The company said it hopes the U.S.D.A. will grant approval for routine use of the vaccine by summer.
