Zoetis gains USDA approval for whole-herd PED vaccine

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 company announced this week.

The new reproductive claim allows for vaccination of sows and gilts before breeding to help provide protection against the reproductive form of the disease.

 The new respiratory claim allows for vaccination of pigs 1-day of age or older against the respiratory form of the disease.

With the new claims, Fostera PRRS is now the first and only PRRS modified-live virus (MLV) vaccine to be licensed for the vaccination of healthy, susceptible swine 1 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,

                Aid in preventing respiratory disease with a duration of immunity of at least 26 weeks,

New research on Fostera PRRS allowed the vaccine to gain one of the USDA’s highest label claims for its reproductive claim, Zoetis says.


In a clinical research study, 33 times more piglets were born alive to gilts vaccinated with Fostera PRRS compared with unvaccinated controls Zoetis says.
