I'm having trouble understanding...how have the new cases went from 1 in 2400, to 1 in 1200, to 1 in 600?
Only 11 reports of this infection are present in over 43,000 people on the drug. This translates to about 1 in 4000, which are also the stats I read in an article. I don't trust the article as much as the math in front of me, so am I missing something about these numbers? By your math, this means that out of the 3,000+ people that were added to the drug in June, 5 of them should end up with this infection. Something seems wrong with that math...please correct me if I'm wrong.
People suffering from MS are willing to take the risk.If the drug holiday works Tysabri will see its sales hit one billion by next year. Besides i'm sure Elan is working on the problem and has other drugs in the pipe line.
