Here is a good article in the New England of Journal of Medicine published last Dec.

It is a well known fact that this is a problem at the government level. I have been in contact with Senator Kerry's office of MA and talked to his aid in charge of health issues. I read her the conversation you had with Sanofi about holding back the drug due to cost issues. She has asked me to send her this thread as she would like to see it. She informed me that the President has just issued an executive order dealing with the shortages of drugs and that the FDA is looking into how to best deal with it. There is also legislation that should be passed this summer dealing with it as it is attached to a funding bill that has to be passed. However the proof will be in the pudding as they say will it change the situation?
My question for MGH or any institution providing BCG treatment is why they are not turing over every rock looking for a substitute? If Sanofi is shipping in early May did they have any idea when you could have treatment?
I know this is not of any help to you and I can understand the stress this is putting you under. I personally feel that if any company is found to be withholding drugs due to cost considerations that they should be held liable for any damages emotionally or health wise their actions cause. I want you to know that I voiced that opinion in the phone call I just placed and shall back it up in future correspondence.
