Is the claim that they have not done this before legitimate?
The most common adjuvants presently allowed are Mercury (Thimerosol) and Aluminum Hydroxide.
So, are these entirely new adjuvants? Is fast tracking these vaccines with experimental adjuvants a good idea?
Note: there is some discrepancy depending on resource wether Thimerosol is an adjuvant or just a preservative. Read linked article above.
In the U.S. an emergency declaration to use experimental additives made by GlaxoSmithKline Plc and Novartis AG to boost a limited supply of shots that will be available to fight the pandemic.
The ingredients, known as adjuvants, may be added for the first time to flu shots in the U.S.
“The question is, do you really feel comfortable throwing this new thing into the mix and do you really need to?” said Treanor, a professor of medicine, microbiology and immunology at the school in Rochester, New York. “I myself, if I had to do it, would really wrestle with that decision.”
As swine flu vaccine becomes available in coming months, boosting compounds known as adjuvants may stretch out limited supplies. But they also pose special challenges for vaccine regulatory agencies in places like Canada and the United States. Neither country has licensed flu vaccines with adjuvants in them before.
