24 November 2020 / Sars-CoV-2 vaccines based on mRNA technology could be approved very soon. It would be the first mRNA vaccine to be approved for use in humans.
In biology, mRNA is a molecule used by living cells to translate DNA into proteins. The new mRNA-based vaccine is based on this principle; mRNA molecules that can be translated into a viral surface protein are produced in the laboratory and then injected. The aim is that the cells produce specific proteins which can be used by the immune system as a template to build up immunity to the virus.
