This paper discusses the significant advancements and future potential of personalized cancer vaccines (PCVs), highlighting their ability to induce long-term, tumor-specific immune responses. It explains how breakthroughs in next-generation sequencing and bioinformatics have enabled the targeting of neoantigens, which are unique to individual tumors. The text reviews early clinical successes of PCVs, often in combination with immune checkpoint inhibitors, in various cancers including melanoma, pancreatic, and renal cell carcinoma, noting their favorable safety profile and potential for long-term immunity. It also explores the development of "off-the-shelf" vaccines and the ongoing large-scale clinical trials that aim to establish PCVs as a standard treatment for preventing recurrence and even intercepting malignancy in high-risk patients. While challenges like manufacturing time and tumor heterogeneity remain, the source conveys strong optimism for PCVs to significantly reduce cancer-related morbidity and mortality.
