Cancer treatments may get a boost from mRNA COVID vaccines

Cancer Treatments and mRNA COVID Vaccines

Cancer patients who received an mRNA COVID vaccine within a few months of their immunotherapy showed improved survival rates, according to health records.

Research published on October 22 in Nature found that lung cancer patients who got the vaccine before immunotherapy lived nearly twice as long as unvaccinated patients.

The correlation suggests that mRNA vaccines — even those not designed for cancer — could make tumors more sensitive to current therapies.

A similar observation was made in people with melanoma, says Elias Sayour, a pediatric oncologist at the University of Florida College of Medicine.

Hua Wang, a cancer vaccine researcher at the University of Illinois Urbana-Champaign, finds this discovery "exciting" and "definitely important".
