ReproCyc ParvoFLEX (Porcine parvovirosis vaccine (inactivated)) is a veterinary vaccine used to protect healthy sows and gilts against reproductive failure caused by porcine parvovirus (PPV). It stimulates active immunity in these animals, which helps prevent transplacental infection and subsequent reproductive issues in their offspring. Protects against fetal death, resorption, and irregular returns to estrus.
