Infectious bronchitis vaccines: study highlights the need for targeted genetic modification of viruses

Scientists at The Pirbright Institute have shown that Infectious bronchitis virus (IBV) vaccines produced in eggs have unpredictable mutations which may be prone to reversion in the field. Live attenuated vaccines, where IBV is weakened so that it causes less severe or no disease, are used in the field as they offer better protection compared […]

Research aims to lower the cost of IBV vaccine production

Infectious bronchitis virus (IBV) vaccines are currently produced in hen’s eggs – a cumbersome and expensive process – because most IBV strains do not grow in cell cultures. In a step towards making vaccine production more efficient and reducing costs, a team led by Dr Erica Bickerton at The Pirbright Institute identified the exact genetic […]
