Anyone been hearing about the new peptide vaccine? It is basically a re-engineered version of the patient's cancer which makes it recognizable to the bodies immune system. It is re-injected into the patient and the body then fights the cancer. The basically biopsy the cancer, rearrange it's peptide chain to make it recognizable as an antigen and then the body actually then recognizes the present cancer as a danger and attacks it. Tumors are vanishing left and right on many patients. All the research is just beginning, but I was impressed by what I saw. (was on TLC the other night) I just thought it might be competition for other companies such as this one regarding cancer treatment. QLT's attack on cancer involves basically tagging the cancer with a drug to make it recognizable for destruction by laser. The peptide vaccine works to make the body fight it's own battle. Anyone know anything more about it? I thought QLT had a unique approach, but this other seems quite impressive.
