The McGill Division of Cancer Epidemiology has recently launched the CATCH study to test the effectiveness of a Carrageenan-based gel in preventing the tranmission of HPV. Carrageenan is derived from red algae, and commonly used as a thickening agent in food products. It could represent an inexpensive method of prevention against the virus, whereas the vaccine and screening procedures are considerably more expensive.
