Cancer Vaccines Help Patients Get Tumor- Free in 2 Studies By David Willams, Live Science Contributor | July 8, 2017 08:39pm ET Cancer vaccines — which are intended to help patients fight cancer by enlisting the individuals' own immune systems to attack cancer cells —showed promise in two small new studies. In both studies, researchers used experimental cancer vaccines to treat patients who had the deadly skin cancer melanoma . And in both studies, tumors completely disappeared in more than half of the patients after they were given their cancer vaccines. The other patients were given another type of treatment that was aimed at further boosting the ability of the individuals' immune systems ' ability to fight cancer, and in some of those cases, these patients' tumors also disappeared.
