SAN ANTONIO, Texas, Dec. 15 /PRNewswire/ -- The long-time dream of a vaccine to prevent breast cancer may be a step closer to reality, according to new research presented Thursday at the 29th Annual San Antonio Breast Cancer Symposium. George Peoples, MD, of the Cancer Vaccine Development Laboratory in Bethesda, MD presented the results of an exciting vaccine trial targeting HER2, a protein that is related to cell growth and is commonly overexpressed in breast cancer cells. Peoples and colleagues have isolated and purified a piece of that protein, called E75, that is normally exposed on the surface of cancer cells. The purified protein is injected into patients once each month, along with factors that stimulate the immune response.
