Genetic engineered Vet vaccine
Newbury – UK researchers have developed a new vaccine by reverse genetics, protecting poultry from infections with the economically relevant bronchitis virus (IBV). The prototype vaccine, developed by scientists at the Institute for Animal Health (IAH) and the vaccine company Intervet UK, can be delivered by robotic “vaccinators” while the chicks are still in the egg. It works on the basis of an extracted virus spike protein, which triggers an immune response. “Our system allows us to exchange the spike protein gene so as to make a vaccine with a spike protein of an appropriate serotype,” explains Prof. David Cavanagh from the IAH.
