PRV/Marker Gold

Description and Vaccination Program

Description
PRV/Marker Gold is a genetically designed, live virus vaccine for the immunization of healthy pigs 3 days of age or older as an aid in the prevention of disease caused by pseudorabies virus (Aujeszky' s disease). Specific genetic modifications have been made in the vaccine virus to optimize safety and efficacy, and to allow serologic differentiation based on either gI or gX deletions.

Indications
For the immunization of healthy pigs 3 days of age or older against pseudorabies, including the respiratory form of the disease.

Dosage and administration
For use in swine only. Aseptically rehydrate PRV/Marker Gold with diluent supplied. Administer 2 ml intramuscularly or intranasally. Pigs nursing non-immune dams may be safely and effectively vaccinated at 3 days of age or older. Pigs nursing immune dams should be vaccinated when maternal antibody levels will allow active immunization. Semi-annual revaccination is recommended for pigs retained for breeding. Sows may be safely vaccinated at any stage of pregnancy.

Caution
Do not vaccinate within 21 days of slaughter. Store at 35°-45°F (2°-7°C). Use entire contents without delay after rehydration. Burn container and all unused contents. Contains gentamicin as a preservative. Anaphylactoid reactions may occur. Antidote: Epinephrine.

Note: Vaccination with PRV/Marker Gold will yield seropositive results in nondifferentiating SN, ELISA and latex agglutination tests.

Presentation
25, 50 and 100 dose vials. Not all pack sizes may be marketed.
