It's all about the risk vs benefit Pete. While some people will take whatever risk is involved with Tysabri, others will not. This becomes an individual decision.

But please don't compare the polio vaccine back in those days with Tysabri of today. What happened with Tysabri and all of the frustration and problems that we are seeing is the result of Biogen/Elan's rush to capitalize on big time revenue. The medical safeguards of today's science are far superior to what they had back in the 50's but unfortunately they weren't used with Tysabri to the extent they could have been.

I continue to read on other MS sites the severe reactions that some Tysabri users are experiencing. These patients used Tysabri during the first round before the drug was pulled. They apparently produced antibodies to the drug and now when they are trying to go back to using Tysabri, the problems are surfacing. They usually can't ever use the drug again and are frustrated more than ever. A lot of this could have been avoided if Biogen took the time to follow their original plan for the trials. You now have to wonder what else was "skimmed over" and not checked out properly. Taking a risk with your health and medication is one thing....taking a risk without being given the proper information is another and something that MS patients don't need to take on.
