Australian researchers unveil adaptable vaccine platform for future mosquito-borne threats
University of Queensland scientists have created the ISVac platform, a mosquito-derived system that can be quickly re-engineered to vaccinate against emerging mosquito-borne diseases in humans.
Researchers at the University of Queensland have announced a new vaccine platform called ISVac, built on a mosquito-specific virus engineered to generate harmless particles. These particles have previously been employed as vaccines against Japanese encephalitis virus in pigs and West Nile virus in crocodiles. Associate Professor Jody Peters described one outlet work as a major step toward a flexible system that can be swiftly customized for human vaccines against emerging mosquito-borne illnesses.
The platform’s design responds to the spread of mosquitoes into new regions driven by climate change, which has already brought Japanese encephalitis to Australia for the first time in 2022. Future applications could include vaccines for dengue, Zika, yellow fever and other mosquito-transmitted diseases. The team hopes the plug-and-play approach will accelerate protection against future outbreaks.
Why it matters
A fast-adaptable vaccine system could help curb the spread of mosquito-borne diseases as they move into new areas.
