Abstract: ABSTRACT Despite its rising promise, cancer immunotherapy remains out of reach for many patients because of the extensive cost of manufacturing immunotherapy products. In this study, we show that intratumoral injections of the trivalent measles, mumps, and rubella (MMR) live attenuated viral vaccine (LAVs) modulates a potent cytotoxic T-cell antitumor immune response, resulting in tumor growth inhibition and improved survival in syngeneic mouse models of hepatocellular carcinoma and colorectal cancer. Using an integrated transcriptomic and proteomic approach, we demonstrated that mechanistically, MMR exerts its antitumor activity by priming innate and adaptive antitumor immune responses, leading to immunologically coordinated cancer cells death. Our findings highlight a promising potential for LAVs, such as MMR, to be repurposed as cost-effective cancer immunotherapy.
