Mercury is one of the most toxic substances known to man. It has been used as a preservative in childhood vaccines for over half a century. In the USA concern about mercury in vaccines has been a bigger issue than the MMR. Mercury was finally removed from the majority of vaccines given to children in he UK in 2004, but not, we are told by the Department of Health (DoH), because of any concerns about its safety.
However, I was concerned that mercury was present in Pandenrix, the swine flu vaccine being offered to many children in the UK during the 2009 pandemic.

What is mercury?
Mercury is a silver-coloured liquid at room temperature; hence its ancient name of ‘quicksilver’, first coined by Aristotle in 415BC. We come across it most often in old-fashioned glass thermometers, blood pressure machines, as fillings in our teeth and, though we may not know it, in vaccines.
The form of mercury in vaccines is called thiomersal (or thimerosal in the USA). Thiomersal is 50% ethylmercury (actually 49.6% mercury by weight)a form of mercury that is
harmful to many areas of the body, particularly the brain, nerves, immune system and kidneys. The question of whether the amount in vaccines could be enough to cause any damage in babies has been hotly debated over recent years.

What is mercury doing in vaccines?
Thiomersal was first registered as an antibacterial and antifungal product by its manufacturer, the drug company Eli Lilly, in 1929 under its trade name,
Merthiolate. It soon became a widely used preservative in vaccines. As long ago as 1935, there was concern that thiomersal could be harmful if injected into dogs. Yet formal safety studies have never been done on humans. This is hard to believe; one of the most toxic elements known to man has been injected into babies for over 60 years without anyone ever checking that it was safe.
