A new study by researchers at The Pirbright Institute shows that avian influenza viruses can combine two techniques to evade vaccine immunity, aiding their spread in the field. Understanding the dynamics between these methods could allow researchers to develop better vaccines that prevent flu viruses circumventing the immune response.

Pirbright reveals new method to study poultry virus (IBV) which could reduce the need to use birds in research
An enzyme called trypsin boosts the growth of infectious bronchitis virus (IBV) strains in lab cell cultures, scientists at The Pirbright Institute have shown. This finding could enable researchers to study strains of the poultry virus that were previously inaccessible and potentially provide alternative vaccine production methods, which currently rely on eggs, therefore reducing the numbers of birds needed for research and vaccine production.
