  • Cancer vaccines that can trigger a person's immune system into killing a tumor have long been a goal. Now two slightly different ways of doing this have had promising results. Catherine Wu of the Dana-Farber Cancer Institute in Boston and colleagues injected up to 20 of the mutant protein molecules into the skin of six people with cancer. Four had no recurrences of their cancer after two years. In the second approach, Ugur Sahin of BioNTech, a German biotech firm, injected people with RNA instead of protein molecules. Normally, cells make proteins using RNA "instructions", and injecting these can lead to some cells turning the RNA into proteins. The end result of both methods was therefore the same: snippets of cancer molecules were exposed to the immune system.
