Some Notes of Mercury in Vaccines Note that the mercury used as a preservative in vaccines is ethylmercury (aka: thiomersal, or thimerosal), which is not known to bioaccumulate, so this form of mercury this will not increase your total body load of bioaccumulated mercury. The reason ethylmercury is being removed from vaccines is because a lot of parents with autistic kids put pressure on governments to do so — even though there is no scientific evidence whatsoever that ethylmercury causes autism. The form of mercury that you find in tuna fish, methylmercury, does bioaccumulate (and so anyone concerned about mercury build-up in their body may want to avoid eating tuna fish regularly). In a vaccine, you get around 10 to 25 micrograms of ethylmercury, which as stated does not bioaccumulate. But in a can of tuna, you will get around 40 micrograms of the methylmercury, which does bioaccumulate. Eating tuna once a month would thus be far worse that having a once monthly vaccine injection. So it seems to me that the banning of the Staphylococcus toxoid vaccine by in Sweden, due to concerns about mercury bioaccumulation, was not really warranted. Perhaps somebody needs to write to the Swedish government. Home Made Staphylococcus Toxoid Vaccine One thing I was looking at some time ago was making my own Staphylococcus toxoid vaccine. You can buy Staphylococcus alpha toxin from a number of suppliers, and what you would need to do, in order to inject it, is to sterilize this alpha toxin. But you need to use very high standards of sterilization, when it comes to injectables. You would also need to know the exact dosage of alpha toxin to put into each of the injections you make up yourself. I am not sure of how much alpha toxin goes into each injection of Staphylococcus toxoid vaccine. Some sellers of alpha toxin are here: Biological Laboratories, Inc. α-Hemolysin from Staphylococcus aureus lyophilized powder alpha-Toxin, Staphylococcus aureus | CAS 12616-52-3 | Calbiochem TOXIN, α HEMOLYSIN (02158522) - MP Biomedicals Though I would only want to make my own Staphylococcus toxoid vaccine if I could get advice from someone knowledgable about alpha toxin, and knowledgable about the right dosage, and knowledgable about how to properly sterilize a preparation to make it safe for injection.
