Early human test results suggest a vaccine can train cancer patients' bodies to seek out and destroy tumour cells.
The therapy, which targets a molecule found in 90 per cent of cancers, eventually could provide an injection that would allow patients' immune systems to fight off common cancers including breast andprostate cancer.
The first results of trials in people, at the Hadassah Medical Centre in Jerusalem, suggest the vaccine can reduce levels of disease. The human work is so preliminary it has yet to be published in a scientific journal.
The scientists behind the vaccine hope to conduct more extensive trials to prove it can be effective against a range of cancers. They believe it could be used to fight small tumours if they are detected early or to help prevent the return and spread of disease in patients who have undergone conventional treatment.
