FLEXMycoPRRS Indications

For vaccination of healthy, susceptible swine 3 weeks of age or older as an aid in the reduction of disease caused by Mycoplasma hyopneumoniae, and as an aid in the prevention of respiratory disease due to Porcine Reproductive and Respiratory Syndrome (PRRS) virus. Indicated for use in PRRS virus positive herds only. The duration of immunity against M. hyopneumoniae is at least 26 weeks. The duration of immunity against PRRS is at least 4 months, which is throughout gestation for sows and gilts, or throughout the finishing period for pigs.

Directions and dosage: Insert a vented transfer spike into Ingelvac MycoFLEX® 2 bottle. Invert the Ingelvac PRRS® MLV 3 vaccine bottle over the Ingelvac MycoFLEX® 2 bottle and slowly insert the transfer spike, releasing the vacuum. Rotate the vials and rehydrate the Ingelvac PRRS® MLV 3 vaccine by adding a portion of the Ingelvac MycoFLEX® 2 vaccine. Shake well and transfer the reconstituted suspension back into the Ingelvac MycoFLEX® 2 bottle to complete to a total volume of 50 mL. Shake well and use immediately. Using aseptic technique, inject a single 1 mL dose intramuscularly. Semi-annual revaccination with Ingelvac MycoFLEX® is recommended for breeding swine.


Store at 35-45°F (2-7°C). Do not freeze. Use entire contents when first opened. Do not vaccinate within 21 days before slaughter. Do not vaccinate breeding age boars. PRRS vaccine virus may be shed and transmitted to other populations of swine which are in contact with vaccinated swine. The duration of potential vaccine virus transmission may vary. Burn containers and all unused contents. In case of anaphylactic reaction, epinephrine is the symptomatic treatment.

Preservative: Neomycin.
