Cancer patients who received an mRNA COVID vaccine within a few months of their immunotherapy lived longer than those who did not, according to health records.
The mRNA COVID-19 vaccines might make some cancer treatments more effective. For example, lung cancer patients who received the vaccine within a few months of immunotherapy lived nearly twice as long as unvaccinated patients, researchers report.
According to Elias Sayour, a pediatric oncologist at the University of Florida College of Medicine, similar observations were made in people with melanoma.
The correlation suggests that mRNA vaccines — even those not designed for cancer — could make tumors more sensitive to current therapies.
Hua Wang, a cancer vaccine researcher at the University of Illinois Urbana-Champaign, notes that this is an exciting finding, stating
It’s definitely important.
