Therapeutic Universal Cancer Vaccine?

Interesting news out of Britain:

A vaccine that can train cancer patients' own bodies to seek out and destroy tumor cells has been developed by scientists. The therapy, which targets a molecule found in 90 per cent of all cancers, could provide a universal injection that allows patients' immune systems to fight off common cancers including breast and prostate cancer. Preliminary results from early clinical trials have shown the vaccine can trigger an immune response in patients and reduce levels of disease. The scientists behind the vaccine now hope to conduct larger trials in patients to prove it can be effective against a range of different cancers.

Therapeutic vaccines are meant to aid those already showing signs of disease.
