Scientists in Taiwan developed new DNA based vaccine for COVID-19; effective in mice
Taiwanese researchers created a novel DNA Covid-19 vaccination that elicited a long-lasting immune response in animal models. The researchers from Taiwan's National Health Research Institutes developed a DNA vaccination that encodes the Covid-19 virus's spike protein. The spike protein aids SARS-CoV-2 in attaching to and infecting the host cell. To circumvent the poor transport of DNA into cells, which is common with such vaccinations, scientists employed electroporation.
Mice and hamsters immunised with the novel DNA vaccine acquired long-lasting antibodies against the SARS-CoV-2 spike protein, according to research. The vaccine has not yet been tested on people. No DNA vaccines have been licenced for human use as of yet.
