Journal says Tysabri needs more study

Looks like the New England Journal of Medicine is weighing the risks and rewards for Tysabri. I say if the people helped are willing to take the risk they should go for it. They should just monitor the person really closely and if they are getting the brain disease then they should stop the treatments immediately. It is a good thing though the Biogen and Elan are making damn sure everything is okay before going ahead.
