LOS ANGELES -- Mayo Clinic researchers have designed a new strategy in the promising field of cancer vaccine research that’s proven to be successful in boosting T cells -- the immune builders akin to a super defense force against cancer cells. Scientists say their strategy may prove to be more successful than methods currently under study and in clinical trials. The research, which was lost to Hurricane Katrina but recovered at Mayo Clinic in Rochester, Minn., will be presented April 17 at the American Association for Cancer Research (AACR) annual meeting. >>> Discuss This Story
