Work carried out by scientists at The Pirbright Institute has revealed that differences in virulence between strains of infectious bursal disease virus (IBDV) may be partly down to changes in a viral protein called VP4. Their findings could help us to understand why very virulent (vv) strains cause high mortality rates in some commercial poultry flocks and could also be used to inform vaccine research and surveillance efforts.

Studies at Pirbright demonstrate two doses of Oxford University’s COVID-19 vaccine boosts immune response in pigs
The Pirbright Institute, working in collaboration with the University of Oxford, have successfully shown that two doses of the ChAdOx1 nCoV-19 (AZD1222) vaccine produce a greater antibody response than a single dose in pigs.
The emergence and subsequent spread of SARS-CoV-2 has caused a global pandemic that continues to have a huge impact on human health and welfare, and the world economy. Vaccines to protect against COVID-19 and to reduce SARS-CoV-2 transmission are urgently required to combat this global emergency.
Scientists at The Pirbright Institute have shown that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), responsible for coronavirus disease (COVID-19), is able to enter cells using the receptors of multiple mammalian species. The broad host range of SARS-CoV-2 confirms the potential risk of infection to a wide range of companion animals, livestock and wildlife.
