Researchers at MD Anderson Cancer Center and the University of Florida have discovered something extraordinary about Pfizer and Moderna COVID vaccines that has nothing to do with preventing virus infections. Cancer patients with advanced lung or skin cancer who received these specific mRNA shots within 100 days of starting immunotherapy treatment lived substantially longer than those who didn’t get vaccinated. The molecule that powers these vaccines appears to act like a siren throughout the body, activating immune cells and helping them respond better to cutting edge cancer drugs called checkpoint inhibitors.
Advanced cancer patients taking checkpoint inhibitors were nearly twice as likely to be alive three years after treatment if they received an mRNA vaccine, while melanoma patients experienced significantly longer median survival rates. Lead researcher Dr. Adam Grippin explains that the vaccines are sensitizing immune resistant tumors to therapy, allowing the body’s own defenses to better recognize and attack cancer cells that had been hiding from immune attack. The research team found their results so promising that they’re preparing a more rigorous study to determine if mRNA coronavirus vaccines should be routinely paired with cancer immunotherapy treatments. This groundbreaking discovery offers hope that widely available vaccines could become powerful allies in the fight against cancer, potentially saving thousands of lives while scientists continue developing personalized mRNA cancer treatments.
