mRNA cancer vaccines are a new type of treatment that use me
mRNA cancer vaccines are a new type of treatment that use messenger RNA (mRNA) to train the body’s immune system to recognize and attack cancer cells. Instead of preventing disease like traditional vaccines, they work by giving cells instructions to produce specific tumor proteins (antigens), which alert the immune system—especially T-cells—to target and destroy cancer. Companies like Moderna and BioNTech are developing personalized versions tailored to each patient’s tumor, often used alongside immunotherapies such as Keytruda. Early clinical trials, particularly in melanoma, have shown promising results in reducing recurrence risk, but these vaccines are still largely experimental and not yet widely available. Overall, mRNA cancer vaccines represent a major step toward more precise, personalized, and immune-based cancer treatment.
