MEDICAL charities play an important role when it comes to human health, yet many, including Cancer Research UK, the British Heart Foundation and the Alzheimer's Society, conduct or fund invasive research on animals.

To highlight this Animal Aid will be holding a Day of Action for Humane Medical Research on November 13, urging people to donate only to charities that are not involved in vivisection.

Not only is animal research harmful to animals, it is also potentially harmful to people. Different species react very differently to different drugs and procedures. Drugs that are shown to be safe in animals may later prove to be dangerous in humans, while valuable cures and treatments can be missed if they fail in animal tests.

Stopping animal experiments will not mean an end to scientific progress. Modern, stateof- the-art non-animal methods allow us to obtain data that is more accurate and relevant to human health, and therefore more likely to lead to effective treatments.
