How do you get "public release" from "advanced studies"? Stop inventing baseless headlines. 

"In Europe, some manufacturers have conducted advance studies using a so-called “mock-up” vaccine. Mock-up vaccines contain an active ingredient for an influenza virus that has not circulated recently in human populations and thus mimics the novelty of a pandemic virus. Such advance studies can greatly expedite regulatory approval."

Yes it would eliminte confusion if WHO defined "active ingredient."

Of course Jim just has to create a headline that isn't even remotely true.  But I thought the article he linked would of interest to those who are following the vaccine push.
