Aug 2, 2025 · Messenger RNA (mRNA) is a fundamental molecule in biological systems. It functions as a single-stranded nucleic acid, similar to DNA but containing uracil instead of thymine. mRNA acts as …

Aug 29, 2025 · Using mRNA is a promising new way to make vaccines to help treat cancer. Vaccines are substances that help your immune system learn to fight off something that doesn’t belong there.

mRNA vaccines have been demonstrated to be safe and effective against COVID-19, many other mRNA vaccines are in the pipeline, including a recently approved RSV mRNA vaccine

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...

Nov 10, 2025 · The type used in current vaccines is called linear mRNA, which delivers its message for a short time before breaking down naturally. A newer version, called self-amplifying mRNA (SAM), …

Messenger RNA, or mRNA, exists in all cells in our bodies and has for millions of years. Just as its name suggests, it acts as a messenger to the cell's machinery that makes proteins, giving instructions for …
