mRNA vaccines proved safe and effective during COVID, review says. Cancer could be next
Reported byCBC Health ↗·Sourced by Goodlede
A comprehensive Lancet review by Dr. Manish Sadarangani and co-authors analyzing published data from January 2020 through December 2025 confirmed mRNA vaccines achieved 87% effectiveness against COVID-19 infection and 94% against mortality; the review also documents that while myocarditis is a rare side effect, COVID infection itself poses far greater cardiac risk, and mRNA vaccine technology now shows promise in personalizing cancer treatment including trials for bladder cancer.
Effectiveness may vary as new viral variants emerge.
