mRNA Cancer Vaccines Show Effectiveness Even Without Key Immune Cells in New Research

Scientists have discovered that mRNA cancer vaccines can destroy tumors even when a key immune cell type is missing, revealing unexpected mechanisms of action for the Nobel Prize-winning technology. The mRNA vaccine technology, which was introduced in 2020 for SARS-CoV-2 and changed the course of the COVID-19 pandemic, is now being adapted to fight cancer. mRNA vaccines are currently in clinical trials for melanoma, small-cell lung cancer, and bladder cancer, opening doors to new ways of preventing and treating cancer.
