tooth connection. All this information as well as evaluation of vaccination quality is available on the mobile phone thanks to a specifically designed APP. Veterinarians in six European countries (Germa- ny, Netherlands, Spain, Italy, Denmark and UK) are gaining further experience with this innova- tive needle free device on commercial pig farms, collecting testimonials from users. As part of the field experience, a study was done recently to confirm that vaccinations are equal to administration with a needle-syringe device. The study included two groups of 55 PRRS negative pigs each, which were given an MLV PRRS vaccine either by conventional needle-syringe or by using the IM needle-free device. After vaccination, diagnostic tests were used to confirm that the vaccine virus re- mained unharmed and could be detected in the blood (by PCR) and resulted in seroconversion, which indicates that live vaccine virus was recog- nized by the pigs’ immune system. The results showed that both groups had similar outcomes con- firming that vaccine administration was done suc- cessfully using the IM needle free device.


One experienced veterinarian, Dr Horst Gaumann, from the VET- team practice in Vechta, Germany, found that: “The device is very us- er-friendly, from my experience the controls and screen menu are easy to use. Also, I find that the set injection volumes and warning lights reduce the risk of vaccine dose cutting.” The practice’s custom- ers also reported: “This new IM needle free device is extremely quiet and painless, which makes vaccinations much more pleasant for both the operator and the piglet.”
