An mRNA vaccine is a type of vaccine that uses a copy of a molecule called messenger RNA (mRNA) to produce an immune response. [1] .

Messenger RNA is a type of RNA that is necessary for protein production. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and …

MRNA — or messenger ribonucleic acid — is a molecule in your cells that copies instructions from your DNA and brings them to your ribosomes (protein-making structures in your cells). Your ribosomes …

Apr 11, 2025 · mRNA vaccines teach the immune system to target specific proteins, often proteins found on a pathogen, like a virus. To do this, they use instructions carried in a genetic molecule called...

May 23, 2025 · Infectious disease experts told ABC News that mRNA and mRNA vaccines have been studied for decades, the vaccines are safe and effective, and that the shots were instrumental in …

Aug 30, 2021 · mRNA vaccines inject cells with instructions to generate a protein that is normally found on the surface of SARS-CoV-2, the virus that causes COVID-19.

Aug 18, 2025 · mRNA is a type of ribonucleic acid (RNA) that helps make proteins. While deoxyribonucleic acid (DNA) stores your body's genetic blueprint, RNA (including mRNA) helps …

Messenger RNA (mRNA) vaccines, like the Pfizer and Moderna COVID-19 vaccines, teach cells how to make a protein that triggers an immune response if someone gets infected.

mRNA vaccines are the newest and most effective vaccines on the market.
