Ingelvac PRRS MLV (Canada)

Dosage

Sows and gilts: Using aseptic technique, inject a single 2 mL dose intramuscularly for the reproductive form of PRRS. The duration of immunity is at least 4 months or throughout gestation. 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 3-4 weeks prior to each breeding, or as directed by your herd veterinarian.

Piglets: Using aseptic technique, inject a single 2 mL dose intramuscularly to swine 3 weeks of age or older for the 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.

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, not approved nor recommended.

Precautions

For use only in swine in PRRS virus positive herds as directed by a veterinarian. 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 by animal. Vaccine virus may be found at varying times post vaccination at locations (tonsil, nasal mucosa, urine, feces) from which the potential for shedding exists. Shedding of vaccine virus may be increased by glucocorticoid treatment and possibly by disease or environmental conditions which stress pigs and elevate levels of endogenous glucocorticoids. Use of the vaccine on farms or pigs transported from the farms where vaccine has been used to farms wanting to remain PRRS virus seronegative is contraindicated. 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 is not known.

Do not vaccinate boars of breeding age. Vaccination during the latter part of gestation of pregnant sows or gilts which are PRRS virus naive and previously unvaccinated can result in piglets born vaccine viremic. The impact of vaccine viremia in the newborn pig is not known.

Vaccination of PRRS negative herds prior to breeding 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. Because the impact of shedding is not known, do not use in boars of breeding age.

Store in dark at 2 - 7°C. Use entire contents when first opened. Do not vaccinate within 21 days before slaughter. Burn containers and all unused contents. Anaphylactoid reactions may occur. Specific herds may be particularly sensitive.
