Scientists are working on a vaccine for cancer. Here’s how it would work

(NEXSTAR) – An advance in vaccine technology is showing promise toward fighting the second-most common cause of death in the United States, cancer.

Scientists are working on developing mRNA vaccines that would work to fight cancer once it’s detected, said Andrew Pekosz, professor and vice chair at the Johns Hopkins Bloomberg School of Public Health, in a recent briefing.

From a technological sense, they would work similar to the Pfizer and Moderna vaccines that were developed to fight COVID-19. These vaccines would be considered “therapeutic vaccines” rather than preventative ones, he explained.
