A personalized mRNA vaccine encodes target information chosen from an individual patient's disease, often mutations found in a tumor. Cells read the delivered messenger RNA and produce target fragments that help train immune cells to recognize matching features on diseased cells.
Personalization requires sample analysis, target selection, manufacturing, delivery, and clinical evaluation. AI may assist some development steps, but a trial result does not establish an AI role unless the study or supporting sources directly document how AI contributed to the vaccine design or production.

A personalized mRNA vaccine is made using information from one patient's illness. It gives the body temporary instructions for showing the immune system particular target features, so immune cells can learn what to look for.
For example, researchers may inspect a patient's tumor, choose unusual markers found there, and create mRNA instructions for those markers. The resulting vaccine is meant for that patient's targets, and clinical trials are needed to learn whether the approach improves health outcomes.
