  "account": "A groundbreaking cancer vaccine, created for each patient based on their unique tumor, is showing promising results in reducing the risk of melanoma tumors reappearing after surgery. According to a major study released by drugmakers Moderna and Merck, the vaccine, called intismeran, reduced the likelihood of melanoma returning by 42% after two years compared to standard post-surgery treatment. The personalized vaccine, made with Nobel Prize-winning mRNA technology, teaches the patient's immune system to recognize and attack \"neoantigens\" - protein markers that should not be present if the cancer re-emerges. While some investors reacted negatively to the full results, experts in the field see this as a significant step forward for cancer immunotherapy research, potentially applicable to various types of cancers.",
