Recent studies suggest that mRNA vaccines used for COVID-19 could also help fight cancer by activating the immune system to recognize and attack tumors. Research conducted on mice and an analysis of medical records from cancer patients who received mRNA-based COVID-19 vaccines before immunotherapy showed these vaccinated patients lived longer than those who did not receive the shots. The findings were presented at the European Society for Medical Oncology Congress in Berlin and published in Nature by researchers from the University of Florida and the University of Texas MD Anderson Cancer Center on October 27, 2025. This discovery indicates that mRNA vaccines could potentially be repurposed as an "off-the-shelf" cancer vaccine.
