Ingelvac PRRS MLV Indications

Recommended for the vaccination of healthy, susceptible swine as an aid in the reduction of disease associated with Porcine Reproductive and Respiratory Syndrome virus, reproductive and respiratory forms.

Recommended for use in healthy, susceptible swine in PRRS virus positive herds only, per label directions.

Directions For Use

Rehydrate the vaccine by adding the full contents of the accompanying liquid diluent to the vaccine vial. Shake well and use immediately. Rehydrate only with the diluent provided; do not mix with other materials. Other diluents may be virucidal.

Dosage: Sows and gilts: Using aseptic technique, inject a single 2 mL dose intramuscularly for the reproductive form of PRRS. Sows and gilts may be vaccinated prior to breeding or at any stage of pregnancy. Vaccination can either be population-targeted as a whole-herd vaccination program where all pregnant and nonpregnant sows and gilts are vaccinated every 3-4 months, or individual animal-targeted by vaccination 3 to 4 weeks prior to each breeding, or as directed by your herd veterinarian. The duration of immunity is at least 4 months or throughout gestation.

Piglets: Using aseptic technique, inject a single 2 mL dose intramuscularly to swine 3 weeks of age or older for respiratory form of PRRS. The duration of immunity is at least 4 months or throughout the finishing period.

Breeding Animals: For use in all swine in PRRS positive herds, except breeding age boars.

Precautions

For veterinary use only. For use only in swine as directed.

Administer only to healthy pigs, gilts, or sows in PRRS virus positive herds, and only by intramuscular injection. Administer the complete 2 mL dose to each pig, gilt, or sow vaccinated. Efficacy and safety of the vaccine at other than the dose or route prescribed on the label is unknown and, therefore, not recommended and not USDA approved. Anaphylactoid reactions may occur.

Antidote: Epinephrine.

Preservative: Neomycin.

Storage Before Use: Store out of direct sunlight in the outer carton. Store at a temperature between 35-45°F (2-7°C). Do not freeze. Use entire contents when first opened. Do not use bottles of damaged product. Do not store reconstituted vaccine.

Withdrawal Period: Vaccinated pigs, gilts, or sows are not to be harvested for human consumption before 21 days after vaccination.

Disposal

After use, burn containers and all unused contents by a procedure allowed by local, state, and Federal regulations.

If human exposure occurs, administer first aid and consult physician immediately.

Many factors must be considered in determining a sound PRRS vaccination program for a particular farm. To be most effective, the vaccine must be administered properly to healthy animals maintained in a proper environment under good management. Stressed or immunosuppressed pigs should not be vaccinated as the efficacy of the vaccine in these animals is unknown. The level of individual animal and herd immunity required will vary with management practices, the degree of exposure to PRRS virus, and the level of susceptibility of each animal. The benefits and risks from vaccination will vary in part with the level of PRRS virus in the herd, and the need for the herd or individual animals to maintain a particular status for virus isolation, serological, or other diagnostic tests. Experience in the field has shown that Ingelvac PRRS MLV was most effective in reducing circulating PRRS field virus when used in a whole-herd protocol. The effect of concurrent or previous infections at or around the time of vaccination on the efficacy of this vaccine in reducing or modifying PRRS virus disease in pigs, gilts, and sows is not known. Therefore, the vaccination program must be carefully planned and implemented in collaboration with the herd veterinarian following label and insert indications and precautions.

Shedding of vaccine virus by vaccinates: 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.

Research (Gorcyca, et al., unpublished) indicates that vaccine virus is found at varying times post vaccination at locations (tonsil, nasal mucosa, urine, feces) from which the potential for shedding exists. The chances of vaccine virus shedding may be increased when animals are treated with glucocorticoids and possibly by disease or environmental conditions which stress pigs and elevate levels of endogenous glucocorticoids.

One field study (Torrison, 1996) indicated that non-vaccinated pigs in contact with Ingelvac® PRRS MLV vaccinated pigs may seroconvert to vaccine virus. Use of the vaccine on farms or transport of pigs from the farms where vaccine has been used to farms wanting to remain PRRS virus seronegative is contraindicated.

Vaccination during the latter part of gestation of pregnant sows or gilts (Gorcyca, et al., 1995b) which are PRRS virus naive and previously unvaccinated can result in piglets born viremic. The impact of vaccine viremia in the newborn pig is not known.

Vaccination prior to breeding of PRRS negative herds or subpopulations within a positive herd may result in a transient reduction of reproductive performance.

Results of field safety studies following whole-herd vaccination showed the percent of mummies born to primiparous gilts was higher among vaccinates than nonvaccinates at two of three test sites, although there was no apparent difference between vaccinates and nonvaccinates in the number of affected gilts.

Vaccination of adult boars may result in the shedding of vaccine virus in the semen (Molitor et al., 1995; Nielsen et al., 1995; Christopher-Hennings et al., 1995). Because the impact of shedding is not known, do not use in boars of breeding age. This vaccine is not USDA licensed for use in breeding boars.
