Australian scientists say they have created a COVID-19 vaccine that can protect against several variants of the virus.
Researchers from the Centenary Institute and the University of Sydney created the CoVEXS5 vaccine, which protects against five variants of the virus, including the "highly immune-evasive" Omicron XBB.1.5 variant and SARS-CoV-1, a relative of SARS-CoV-2.
Studies showed reduced virus levels in the lungs of vaccinated mice by 99.9 per cent, compared to unvaccinated controls.
It also triggered high levels of virus-blocking antibodies and activated special immune T-cells in the lungs, which are critical for the body to fight the virus.
The CoVEXS5 vaccine features a unique version of the spike protein, fusing protein elements from several different COVID-19 variants into one single structure.
