New mRNA vaccine fights brain cancer in children by triggering attack from within [Video]

Brain cancers remain among the most challenging tumors to treat. They often don’t respond to traditional treatments because many chemotherapies are unable to penetrate the protective barrier around the brain. Other treatments like radiation and surgery can leave patients with lifelong debilitating side effects.

As a result, brain cancer is the leading cause of cancer-related death in children. Brain tumors in children frequently do not respond to treatments developed for adults, likely due to the fact that pediatric brain cancers are not as well-studied as adult brain cancers. There is an urgent need to develop new treatments specific to children.

We developed a new messenger-RNA, or mRNA, cancer vaccine, described in newly published research, that can deliver treatments more effectively in children who have brain cancer and teach their immune systems to fight back.
