Genetic engineering could revolutionise poultry vaccines

Genetic engineering has the potential to unlock a new generation of poultry vaccines, according to leading UK researchers. Scientists at the Pirbright Institute have used GM technology to develop a more efficient and effective vaccine for Marek’s disease and believe the technique could pave the way for other vaccines. More than 20 billion vaccine doses are currently administered across the world in a bid to stem the disease, which can lead to bird losses of up to 20%. Turkey herpes virus (HVT
