Intramuscular or intradermal administration of Porcilis PRRS results in the production of specific antibodies and active immunisation against infection caused by European strains of Porcine Reproductive and Respiratory Syndrome virus. Immunity is enhanced by the adjuvant α-tocopheryl included in the solvent for reconstitution.

On the basis of antibodies induced by vaccination, it is not possible to discriminate vaccinated animals from those naturally infected with European strains of PRRS virus.
