American scientists say they have developed a vaccine which has prevented breast cancer from developing in mice. The researchers – whose findings are published in the journal, Nature Medicine – are now planning to conduct trials of the drug in humans. But they warn that it could be some years before the vaccine is widely available. The immunologist who led the research says the vaccine targets a protein found in most breast tumours. Vincent Tuohy, from the Cleveland Clinic Lerner Research Institute, said: “We believe that this vaccine will someday be used to prevent breast cancer in adult women in the same way that vaccines have prevented many childhood diseases. – From BBC
