Mayo Clinic researchers injected patients with an engineered measles virus that is similar to the measles vaccine. But this wasn’t your normal vaccine; the virus was engineered to make it toxic only to cancer cells, and Stacy was given enough to vaccinate 10 million people.
The measles virus makes cancer cells group together and explode. This gets rid of the cancer cells and triggers the immune system to react against them. For Stacy, it worked. One other patient in the trial experienced a reduction in bone marrow cancer and tumor growth, but cancer returned after 9 months.
While success in one patient doesn’t prove that researchers have found this single-shot cure, it’s definitely a proof of concept. The virus killed cancer cells while leaving other body cells unharmed, and while cancer patients have been treated with viruses in the past, this is the first time that a patient with full-body cancer has experienced remission after virotherapy.
Virotherapy has been tested in animal models in the hope of developing treatments for breast cancer, endometrial cancer, gallbladder cancer, and even canine cancer. A single-shot cure for cancer could revolutionize treatments for our loved ones and pets! Read more about this particular study here:
