Vaccine maker Moderna announced Friday that it's suing rival drugmakers Pfizer and BioNtech for patent infringement. The lawsuit alleges the two companies used certain key features of technology Moderna developed to make their COVID-19 vaccine. It argues that Pfizer and BioNtech's vaccine infringes patents Moderna filed between 2010 and 2016 for its messenger RNA or mRNA technology.
All three companies' COVID-19 vaccines used mRNA technology which is a new way to make vaccines. In the past, vaccines were generally made using parts of a virus, or inactivated virus, to stimulate an immune response. With mRNA technology, the vaccine uses messenger RNA created in a lab to send genetic instructions that teach our cells to make a protein or part of a protein that triggers an immune response.
