I am sorry if I am repeating myself Firestormm ( and to anyone else reading this thread), please check out the "The MIT Consortium of Adventitious Agent Contamination in Biomanufacturing. I tried to attach a powerpoint but it didn't work. Here is a link: http://www.slideshare.net/mewiebe/pda-annual-mtg-2012-caacb-talk I have no interest in arguing with anyone. I simply want people to be aware that there are very real risks that the governments and pharmaceutical organizations have recognized. No one wants any type of public response to this very present (IMHO) danger. To understand the risk, you must understand the science. No understanding means you are at risk. Ignorance is not bliss. Ignorance increases you risk. Firestormm, you statement " Until such time as one of these family of viruses or any virus is connected to human infection and human disease - all the vaccine manufacturers can do if they think a risk exists is heighten their safety protocols and look for better ways of controlling biohazards." is most timely. They ARE trying to make things safer but until the know what they are dealing with, IMHO.. there will be no public warnings of their concerns. It is simply too huge. Brain dead here again but that is the norm for me after working 10+ hours. I still work full time in a clinical laboratory just because I can do most of it with minimal brain capacity. Would love to be able to return to my former life.
