A needle-free vaccine patch could better fight COVID-19 variants, such as Omicron and Delta, than a traditional needle vaccine according to a University of Queensland study in mice.
The research, conducted in partnership with Brisbane biotechnology company Vaxxas, tested the Hexapro SARS-CoV-2 spike vaccine using the Vaxxas high-density microarray patch (HD-MAP) technology, and the results found the patch was far more effective at neutralising COVID-19 variants.
