A cancer treatment that uses messengerRNA to launch an immune attack against cancer cells can shrink tumours completely in mice. It is currently being tested in humans.

Messenger RNAs, or mRNAs, are molecules that tell cells how to make proteins. With the introduction of mRNA-covid-19 vaccines, they have gained a lot of attention.

BioNTech, the German firm that created Pfizers mRNA Covid-19 vaccine is currently testing whether mRNAs are suitable for treating cancer.
