Is there a new way to vaccinate against infectious bronchitis viruses?

US Poultry and the US Poultry Foundation have funded a research project at the University of Georgia that explores new methods for vaccinating poultry against infectious bronchitis viruses.

The research was made possible in part by an endowing Foundation gift from Fieldale Farms and is part of the Association’s comprehensive research programme encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report, along with information on other Association research, may be obtained through US Poultry's website. The project summary is as follows.

Project #709

Infectious bronchitis virus spike protein-pseudotyped virus particles for vaccine applications

(Dr Brian Jordan and Dr Mark Jackwood, University of Georgia, Athens, Georgia )

Dr Brian Jordan and Dr Mark Jackwood at the University of Georgia Poultry Diagnostic and Research Centre recently completed a research project that evaluated the potential for pseudotyped vesicular stomatitis virus (VSV) particles carrying infectious bronchitis virus (IBV) spike proteins on their surface to be used as a vaccine for emerging variant IBVs. The objective was to determine if a novel vaccine production method could be used to shorten the variant-to-vaccine timeline and be efficacious at protection against the new IBVs. Data showed that the specific pathogen free chicks did not immunologically respond to the GA08 pseudotyped VSV particles.
