Researchers at Pirbright investigate the emergence of new bird flu viruses with the potential to infect people

Pirbright scientists have discovered that infection with two strains of avian flu can lead to the emergence of a new virus strain with the potential to jump from birds to humans. Human cases of avian influenza are extremely rare but can occur if a person comes into very close contact with an…

Pirbright’s new bird flu vaccine provides rapid protection, could reduce virus spread and is less costly to produce

An improved poultry influenza vaccine has been developed by researchers from The Pirbright Institute. The potential vaccine triggers a rapid immune response which protects chickens against signs of disease and reduces the level of virus that they could pass on, a key element to halting the spread of…

Pirbright scientists reveal more clues on how bird flu viruses evade vaccine immunity

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…

Pirbright shows bird flu mutations could increase threat to poultry, but reduce potential to infect humans

Mutations in the H7N9 bird flu virus increase its replication rate and stability in avian cells, but reduce its preference for infecting human cells, a study from The Pirbright Institute has found. The results show that outbreaks in birds caused by strains with these mutations could pose a lower…

Influenza antibodies made by Pirbright reduce disease in chickens

Scientists at The Pirbright Institute have engineered synthetic antibody molecules that can be administered to poultry to reduce the symptoms of influenza, as well as decreasing the amount of influenza virus they shed into the environment. These results suggest that there is potential for their use…

Bird flu and Marek’s disease vaccine developed by Pirbright scientists

Scientists at The Pirbright Institute have used genetic engineering to develop a vaccine that protects birds against both Marek’s disease and avian influenza, also known as bird flu. The process is faster and more efficient compared to previous methods, which will allow poultry vaccine producers to…

Pirbright scientists identify high risk poultry trading practices for flu in Vietnam

Scientists at The Pirbright Institute have found that the transmission of avian influenza viruses in Vietnam is influenced by the structure of live poultry trading networks. Their work has identified the groups that are most likely to employ trade practices that impact the risk of infection in…

Bird flu viruses could escape vaccine immunity while increasing potential to infect humans

Research led by The Pirbright Institute has shown mutant H9N2 bird flu viruses isolated from Pakistan are able to escape immune responses and adapt to infect humans. This could result in reduced vaccine efficiency and the possibility of human outbreaks. Published in the journal Emerging Infectious…
