Hipradermic®, a needle-free injection device, has been designed as a new option for the intradermal (ID) vaccination of the MLV UNISTRAIN® PRRS on swine farms. Intradermal and needle-free vaccination in pigs has been reported to improve animal welfare, to generate an effective immune response and to be easy to administer, amongst other benefits (Chase et al., 2008). The aim of this study was to demonstrate that UNISTRAIN® PRRS administered using Hipradermic® was as safe and efficacious as when administered via the conventional intramuscular (IM) and intradermal (ID) route in a mass vaccination in sows.
