Which vaccine is the first to use mRNA technology to gain widespread global approval?
Quick Answer
The first widely used mRNA vaccines were the COVID-19 vaccines from Pfizer-BioNTech and Moderna, authorized in late 2020. They marked the first large-scale use of mRNA technology in humans.
The Full Story
The COVID-19 vaccines developed by Pfizer-BioNTech and Moderna were the first mRNA vaccines to receive widespread authorization and use at global scale, beginning in 2020. They taught cells to make a harmless piece of the coronavirus spike protein, triggering immunity without using live virus. Their rapid development showed the flexibility of mRNA technology, which had been studied for years before the pandemic. This success accelerated interest in mRNA vaccines for influenza, RSV, and other diseases.
