Porcine Circovirus Vaccine, Type 2, Killed Virus

Contains 50 mL / 25 doses for sows and gilts, 100 doses for piglets.


Circovac® vaccine is an injectable emulsion made from combining a suspension containing a killed porcine circovirus type 2 (PCV2), and an oily emulsion.

Circovac Indications

Sows and gilts:

Circovac® vaccine is indicated for the passive immunisation of piglets via the colostrum following vaccination of sows and gilts and as an aid in the control of PCV2 infection. Efficacy of the vaccine was evaluated by challenging piglets at up to 5 weeks of age.


Circovac is indicated for the vaccination of piglets 3 weeks of age or older to reduce viremia, virus in lymphoid tissue and fecal excretion of PCV2 and to aid in the reduction of clinical signs associated with porcine circovirus-associated disease. Efficacy was determined through piglet vaccination-challenge studies. The onset of protection is 2 weeks post-vaccination and the duration of immunity for reduction of viremia and fecal excretion of virus is at least 14 weeks. The efficacy of the vaccine in the face of intermediate to high levels of maternal antibodies has been demonstrated.

For optimal results, vaccination should be part of a comprehensive health management program.


Aseptically inject the content of the suspension vial into the emulsion vial and mix gently. After reconstitution, use within 3 hours.

Sows and gilts:

Administer 2 mL (1 dose) by deep intramuscular route according to the following vaccination scheme:

● Primary vaccination: 2 injections before farrowing, 3 weeks apart, with the second injection 3 weeks before farrowing.

● Revaccination: One injection at each gestation, at least 2 to 4 weeks before farrowing.

Piglets from 3 weeks of age:

Administer 0.5 mL (1 dose) by deep intramuscular route.

General directions for reconstitution of vaccine:

Shake the vial containing the antigen suspension vigorously (3 times) before using. Aseptically reconstitute the antigen suspension with the accompanying emulsion as described below:

● Draw up the content of the antigen suspension vial into a sterile syringe.

● Inject the content of the syringe into the vial of emulsion with the needle positioned above the level of liquid to allow pressure equilibration.

● Remove the syringe and discard.

● Gently blend the 2 components by inverting the vial manually 5 - 10 times. Do not shake.


Store at 2-7°C. Do not freeze. Do not expose to heat or direct light. Use entire

contents when first opened. Discard empty containers and all unused contents according to local regulations. Do not vaccinate within 21 days prior to slaughter. In sows and gilts, vaccination may induce a transient oedema and a small local reaction without any effect on the health and the reproductive performance of the animals. In piglets, vaccination may induce at the injection site a transient redness and swelling. Vaccination may exceptionally cause hypersensitivity reactions. In such cases, an appropriate symptomatic treatment should be provided. Contains thimerosal and gentamicin as preservatives.


Humans injected with this vaccine should consult a physician immediately. Advise medical personnel that the vaccine is an oil emulsion type.
