The duration of immunity is at least 4 months for the reproductive form of PRRS virus. The duration of immunity has not been determined for porcine parvovirus.

Directions and dosage: Rehydrate the vaccine by adding a portion of the contents of the ReproCyc® ParvoFLEX vial to the Ingelvac PRRSFLEX® MLV vaccine vial. Shake well and transfer the reconstituted suspension back into the ReproCyc® ParvoFLEX vial. Mix with the remaining ReproCyc® ParvoFLEX contents to complete the total volume. Shake well and use immediately. Using aseptic technique, inject a single 2 mL dose of vaccine intramuscularly. Administer a second 2 mL intramuscular dose of ReproCyc® ParvoFLEX 3 weeks later. For more information on revaccination frequency, consult your veterinarian.


Store out of direct sunlight at 35 - 46°F (2 - 8°C). Do not freeze. Use entire contents when first opened. Do not vaccinate within 21 days before slaughter. Do not mix with other products, except as specified on the carton. In case of anaphylactoid reaction, administer epinephrine. For use in PRRS virus positive herds only. 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. Use of the vaccine in herds intended to remain PRRS virus seronegative is contraindicated. Introduction of vaccinated pigs into herds intended to remain PRRS virus seronegative is contraindicated. Vaccine is safe in pregnant swine. Specific herds may be particularly sensitive. Fetal health risks associated with the vaccination of pregnant animals with this vaccine cannot be unequivocally determined during clinical trials conducted for licensure. Appropriate strategies to address the risks associated with vaccine use in pregnant animals should be discussed with a veterinarian. In case of human exposure, contact a physician. Inactivate unused contents before disposal.
