The Roslin Institute in Scotland has conducted a successful trial of needle-free vaccination of pigs. It’s a first for vaccinations.
It used technology developed by aVaxziPen to vaccinate pigs to generate immunity to Porcine Respiratory and Reproductive Syndrome virus (PRRS).
A solid-dose vaccine is placed just below the skin and is combined with a nasal spray.
The Roslin Institute said this marks the first time that needle-free, solid-dose vaccine technology has been shown to work in any species.
Despite almost four decades of research, modified live vaccines (MLV) remain critical for PRRS control, especially in unstable herds, the researchers said.
