I was looking at the chefarzfrau site. I've had a question about a couple of the pml cases statistics and decided to throw it out to see if anyone has an answer. There are 2 cases in the U.S. both July 2010, one had 57 infusions the other 59. Tysabri was put back on the market July 2006, getting an infusion every 4 weeks would put the most infusions at 52-53 at 7/2010. If they had been in the trial they would've had many more infusions. So... I am confused

Thanks
