The aim of this study was to demonstrate that UNISTRAIN® PRRS administered by the intradermal route (ID) with a suitable device was as effective as when administered with a conventional intramuscular injection (using needle and syringe) in piglets after a heterologous challenge at 24 weeks post-vaccination.

The obtained results allow us to conclude that the duration of immunity of the UNISTRAIN® PRRS vaccine was achieved 24 weeks after vaccination. In addition, UNISTRAIN® PRRS administered in piglets by the intradermal route with a suitable device had a comparable effect on the fast clearance of the virus to IM administration using a traditional syringe and needle. UNISTRAIN® PRRS administered ID or IM appears to be a useful tool to decrease viraemia and thus achieve a reduction in the infection pressure of PRRSV on an infected farm.
