mRNA-based COVID vaccines may enhance the immune response to certain cancer treatments

Advanced lung and skin cancer patients lived substantially longer when vaccinated early during immunotherapy

The findings suggest the vaccine's mRNA molecule acts as an immune boost to help fight tumors

FRIDAY, Oct. 24, 2025 (HealthDay News) — The mRNA technology powering some COVID vaccines may hold a surprising benefit for advanced cancer patients: a potential ability to "rev up" the immune system to better use immunotherapy medicines to attack tumors.

Preliminary research published Oct. 22 in the journal Nature found that patients with advanced lung or skin cancer who received a Pfizer or Moderna COVID shot within 100 days of starting immunotherapy lived significantly longer tha
