In less than ten years, we might have a reliable breast cancer vaccine. Also, a vaccine against the development of ovarian cancer is under work. That's the latest report coming from the researchers at the Mayo Clinic in Jacksonville, Florida. At the moment, the scientist created an immunotherapy cure that makes the immune system identify and destroy breast cancer cells. For now, the breast cancer vaccine worked for one patient, while for the second one, it only shows some positive results. "It's supposed to stimulate a patient's own immune response so that the immune cells, like t-cells, would go in and attack the cancer," explained an oncologist at Mayo Clinic, Dr. Saranya Chumsri. The researchers added that, before the breast cancer vaccine becomes available to large clinical trials on more human patients, the FDA has to approve it. That process is lengthy and consists of three stages. The scientists estimate the FDA would start the procedure in about three years. Mayo Clinic Stated That A Reliable Breast Cancer Vaccine Would Be Available Within Ten Years "It is reasonable to say that we could have a vaccine within eight years that may be available to patients through their pharmacy or their doctor," said Keith L. Knutson, Ph.D., the principal investigator at Mayo Clinic. "We know that they're safe. We know that they stimulate the immune system to fight cancer. We know that they have had a positive impact on ovarian and breast cancer," he added. Immunotherapy gained traction in the 1990s. Since then, scientists from around the world have been working hard to develop immunotherapy-based treatments to kill cancer cells without also destroying healthy cells in the body. "Other individuals are working on lung and prostate and other cancers. Some are very similar to the approaches we are taking, but different cellular processes have gone wrong in different cancers," concluded Keith L. Knutson.
