Researchers at the University of British Columbia have synthesized a vaccine that may prevent the spread of West Nile virus in birds, a development that could help protect some vulnerable populations.

“West Nile virus has been identified as a threat contributing to the extinction of some rare bird species,” says Joanne Young, a UBC vaccine researcher.

“A bird vaccine would go a long way to helping combat these adverse effects.”

Some endangered bird species like the eastern loggerhead shrike and California condor have proven especially susceptible to the virus, with mortality rates approaching 100 per cent in some cases.
