The Czech company Biotest near from Prague got from Austria a testing batch of the new flu vaccine for 2009 from the american company Baxter. In february they have found that the vaccine was contaminated by the H5N1 - Avian flu virus, which is on the list of the possible biological weapons and is one of the most dangerous biological agents on the Earth - with more than 60% death rate . All the testing animals in Biotest were subsequently destroyed and all the workers in the company were put in quarantine. Luckily nobody contracted the disease. Subsequently the same problem of the Baxter vaccines contamination with H5N1 was found in the laboratories in Slovenia, Austria and Germany, which confirms that the source of the contagion was in fact the Baxter vaccine, which could be very probable, because Baxter is one of the companies, which are developing the vaccines against H5N1.
This has led some to suggest that it is a deliberate attempt to create a pandemic. That sounds more like a conspiracy theory, and most of these reports, except possiblt the original Czech ones, seem to emanate from conspiracy theory factories.
But I've managed to survive every winter of my life so far without resorting to flu vaccines, in spite of my Medical Aid sending out letters recommending them, and I think this year will be no exception.
