If “accidental” contamination is virtually impossible,
then intentional contamination likely

The shocking answer is that this couldn’t have been an accident. Why? Because Baxter International adheres to something called BSL3 (biosafety level 3)-a set of laboratory safety protocols that prevent the cross-contamination of materials. Laboratory personnel have specific training in handling pathogenic and potentially lethal agents and are supervised by competent scientists who are experienced in working with these agents. …All procedures involving the manipulation of infectious materials are conducted within biological safety cabinets or other physical containment devices, or by personnel wearing appropriate protective clothing and equipment. The laboratory has special engineering and design features.”
Under the BSL3 code of conduct, it is impossible for live avian flu viruses to contaminate production vaccine materials that are shipped to vendors throughout the world.
This leaves only two possibilities
