Phase 3 clinical trials, expected to begin sometime in 2023, are where the vaccine will be tested on a larger scale. Moderna’s cancer vaccine just completed its phase 2 trial, which is the first step in testing its safety and effectiveness. It’s too early to say when a vaccine will be ready to treat melanoma outside of a clinical trial. For example, current immunotherapy treatment can affect an individual’s thyroid and adrenal glands.” When will the melanoma vaccine be available? “But, side effects are likely similar to current immunotherapy treatments. “We’re still waiting for a more formal presentation of the safety data from the cancer vaccine study,” says Dr. The mRNA vaccines, such as those used for COVID-19, have proven to be exceedingly safe thus far. Immunotherapy has become an effective treatment for many patients. In that period, immunotherapy emerged as a new approach to treating cancer. The mRNA COVID-19 vaccines were developed quickly because of the decades of work already done on cancer vaccines. It produces perfect copies of the mutations for the immune system to recognize and destroy. When the vaccine is injected, the patient's cells act as a manufacturing plant. Finally, they used that information to design a tailor-made cancer vaccine. They then analyzed the samples to decode their genetic sequence and isolate mutant proteins associated only with the cancer. To build the vaccine, researchers took samples of patients' tumors and healthy tissue. “And while they’re successful in revving up the immune system to fight cancer, we are realizing that combining them with another medication may make them even more effective.” “We are already using immunotherapies like Keytruda® to treat melanoma,” says surgical oncologist Joshua Mammen, MD, PhD.
