Well, I´m only sure that it´s unsafe. HOW unsafe I suppose depends on what "destined subject organism" you are...

'Suitable adjuvants can be selected from mineral gels, aluminium hydroxide, surface active substances, lysolecithin, pluronic polyols, polyanions or oil emulsions such as water in oil or oil in water, or a combination thereof. Of course, the selection of the adjuvant depends on the intended use. E.g. toxicity may depend on the destined subject organism and can vary from no toxicity to high toxicity.'

The above is taken from the Baxter Vaccine Patent Application US 2009/0060950, filed on the 28th Aug 2008!! It is for...

'... In particular preferred embodiments the composition or vaccine comprises more than one antigen ... such as influenza A and influenza B in particular selected from of one or more of the human H1N1, H2N2, H3N2, H5N1, H7N7, H1N2, H9N2, H7N2, H7N3, H10N7 subtypes, of the pig flu H1N1, H1N2, H3N1 and H3N2 subtypes, of the dog or horse flu H7N7, H3N8 subtypes or of the avian H5N1, H7N2, H1N7, H7N3, H13N6, H5N9, H11N6, H3N8, H9N2, H5N2, H4N8, H10N7, H2N2, H8N4, H14N5, H6N5, H12N5 subtypes.'

I find the fact that a patent was filed for a vaccine 7 months before the virus was "discovered" in Mexico in april 2009, in itself quite worrying...

I´m sorry, but I don´t think there IS a simple answer to your question...unless you ask your doctor of course, who will probably tell you to not worry, "it´s very safe".

Some research on the ingredients of the vaccines might shed some light on as to wheter you like to have this stuff injected into yourself and your family.

Good luck.
