Search for a Cancer Vaccine Beginning to Show Promise
As Reported by TIME. 2009 Sept 14
The search for an effective cancer vaccine has been elusive until now, but positive results for separate vaccines against melanoma and lymphoma were finally reported this past June. Although the theory behind a cancer vaccine seems logical—enlist the immune system to seek and destroy cancer cells—it also poses an inherent problem, specifically, that cancer cells aren’t foreign pathogens, such as bacteria or viruses, but cells from a person’s own body. Getting a vaccine to work against cancer requires a deep understanding of how the immune system works and how malignant cells evade detection. A feature article in the September 14 issue of TIME, written by Alice Park, explains the quest thus far for cancer vaccines.
