What is mRNA vaccine technology?
MedicineVaccine technology
Quick Answer
mRNA vaccine technology uses messenger RNA to give cells instructions to make a harmless piece of a pathogen, which prompts an immune response. It does not change a person’s DNA.
The Full Story
In an mRNA vaccine, lipid particles deliver mRNA into cells, where it instructs the cells to make a target protein for a short time. The immune system then learns to recognize that protein and builds antibodies and T-cell responses. This platform was used at scale in the COVID-19 vaccines from Pfizer-BioNTech and Moderna, authorized in 2020. Researchers are also exploring mRNA vaccines for influenza, RSV, and some cancers.
Key Facts
1.mRNA vaccines deliver genetic instructions, not live virus
2.The technology was used widely in COVID-19 vaccines in 2020
3.It does not alter human DNA
