University of Queensland scientists have tested a COVID-19 vaccine patch that delivers a pain-free dose and removes the need for cold chain transport. The Australian-US team researchers developed the novel microneedle patch to deliver a COVID-19 DNA vaccine into the skin. How does the vaccine patch work? The team used patches measuring one square centimeter that were dotted with more than 5,000 microscopic spikes. The researchers used a so-called 'subunit' vaccine that reproduces the spikes that dot the surface of the coronavirus.
