Personalized NeoAntigen Cancer Vaccine: The purpose of this study is to determine if it is possible to make and administer safely a vaccine against kidney cancer by using information gained from specific characteristics of the participant's own kidney cancer. It is known that kidney cancers have mutations (changes in genetic material) that are specific to an individual patient and tumor. These mutations can cause the tumor cells to produce proteins that appear very different from the body's own cells. It is possible that these proteins used in a vaccine may induce strong immune responses, which may help the participant's body fight any tumor cells that could cause the kidney cancer to come back in the future. The study will examine the safety of the vaccine when given at several different time points and will examine the participant's blood cells for signs that the vaccine induced an immune response.
