Should the poultry industry transition to new lab-grown methods for vaccine production?
Researchers at The Pirbright Institute have developed a new method for producing Infectious Bronchitis Virus (IBV) vaccines using cell culture. This technique bypasses the traditional reliance on embryonated hens' eggs, offering a more efficient way to manage poultry disease outbreaks.
Why it matters
The reliance on egg-based production currently limits the speed of vaccine manufacturing, which is critical for controlling emerging IBV variants. This new approach aims to shorten production timelines and improve the overall efficacy of disease control in the poultry industry.
The study utilized reverse genetics to substitute the spike gene of pathogenic strain D388 with the spike gene from attenuated strain Beaudette, allowing the virus to grow in Vero cell lines.
The players
The Pirbright Institute
This is a world-leading research center in the United Kingdom that specializes in the study of viral diseases of livestock and viruses that spread from animals to humans.
Journal of Virology
This is a prominent peer-reviewed scientific journal published by the American Society for Microbiology that covers all aspects of virology.
The details
By using reverse genetics, the team created a modified virus that showed an attenuated phenotype in chickens while eliciting a broader, more controlled innate immune response. This transition to Vero cells eliminates the dependency on egg supply chains that have historically slowed vaccine development.
Timeline

The Big Picture
This development marks a paradigm shift in veterinary virology, moving the industry away from legacy systems toward standardized cell-based platforms. The findings could serve as a model for accelerating response times to other respiratory viruses affecting the global livestock sector.
The success of this method suggests that poultry producers may soon benefit from faster vaccine availability, potentially reducing economic losses from IBV outbreaks. These advancements may eventually lead to higher food security and more stable pricing for poultry products globally.
The takeaway
Transitioning to cell culture methods creates a more reliable and scalable pipeline for critical animal vaccines. This innovation demonstrates how modern genetic engineering can successfully replace outdated, time-intensive production standards.
