These are the kind of things that make folks question any organization (FDA)... two doses, four doses... let the 'experts' do it instead of putting in your two cents, unless there's an ulterior motive? Making people wonder why... seems dollars ALWAYS tell the story, unfortunately. Not sure there's any other way for those who believe in this drug to explain what's happened the past 20 months or so... it's quite frustrating to say the least...
