Fostera PRRS, from Zoetis, is now licensed for whole herd protection against both the respiratory and reproductive forms of disease caused by porcine reproductive and respiratory syndrome (PRRS) virus.
The new reproductive claim, recently granted by the U.S. Department of Agriculture, allows for vaccination of sows and gilts pre-breeding to help provide protection against the reproductive form of the disease. The new respiratory claim allows for vaccination of pigs one day of age or older against the respiratory form of the disease.
With the new claims, Zoetis said Fostera PRRS is now the first and only PRRS modified-live virus (MLV) vaccine to be licensed for the vaccination of healthy, susceptible swine one day of age or older in PRRS virus-positive herds to:
* Aid in preventing reproductive disease with a duration of immunity of at least 19 weeks [Sows and gilts should be vaccinated pre-breeding. Revaccinate prior to subsequent breeding or as recommended by your veterinarian] and
* Aid in preventing respiratory disease with a duration of immunity of at least 26 weeks.
