According to Wikipedia, “Polysorbate 80 (brand names include Alkest, Canarcel and Tween, which is a registered trademark of ICI Americas, Inc.) is a nonionic surfactant”, a compound which “lowers the surface tension between two liquids or between a liquid and a solid…Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.”
In a 2006 article, Sherri Tenpenny DO quotes from her book, Fowl! Bird Flu: It’s Not What You Think, Chapter 8 of which describes how seasonal influenza vaccines are made. She informs that formaldehyde is used to kill the cultured influenza viruses, Triton X-100 is added to increase development of an antibody response, and “Two other chemicals, tri-butylphosphate and polysorbate 80, then become part of the ‘chemical soup’ of the vaccine. “Tri-butylphosphate, a detergent and polysorbate 80, also known as Tween80™, is an emulsifier. Both are used to disrupt the surface of the virus, making the (H) and (N) antigens more accessible to the immune system…. Resin is added to ostensibly eliminate ‘substantial portions’ of these chemicals, but undoubtedly, residuals of these chemicals remain in the vaccine when injected.”
The combining of other risky ingredients with polysorbate 80 in flu shots as well as in many other vaccines is especially concerning. The blood-brain barrier (BBB) is weak and easily trespassed during the first 2-3 years of life and often during the senior years. In other age groups the BBB normally restricts passage of substances from the bloodstream. But, an article by paediatrician Dr Lawrence Palevsky suggests that, even for the latter, polysorbate 80 in vaccines may allow other vaccine ingredients to enter the brain. He warns, “Polysorbate-80 is used in pharmacology to assist in the delivery of certain drugs or chemotherapeutic agents across the blood-brain-barrier.”
An article discussing Membrane Attack Complex (MAC) explains how this is possible. It declares: “Injected detergents trespass on an immune process that holds life and death control over cells”. MAC proteins are a particularly vicious component of our immune systems which kill the cells of pathogens by tunneling through their surface membranes, causing them to leak or explode. There are similarities between MAC proteins and detergents, but the latter can be much more harmful. The actions of injected detergents are not regulated as are those of MAC. They attack cells at random so may attack our own cells, and they ignore and disrupt immune system feedback or signals to stop attacking.
One of the proteins which regulate MAC is CD59. It prevents MAC proteins from binding to our cells and causing them to develop holes and rupture. Studies indicate that when CD59 protection is lacking (as is the case with injected detergents), several conditions may result: damaged neuromuscular transmission junctions, rheumatoid arthritis, kidney disease, stroke, or fatal cerebral hemorrhage. Added to these risks, other studies show that, because they’re not easily metabolized, detergents may remain in our bodies for a long time; P450 enzyme and the liver work to eliminate them but may be damaged in the process. Detergent breakdown products include octylphenols which are endocrine disruptors, depress immune function, deplete glutathione, also induce cell death, can pass through breast milk – and are even more persistent than detergents!
When it’s used as a vaccine emulsifier, numerous studies confirm that polysorbate 80 can increase cell permeability, damage and bursting. Furthermore, after injection it can quickly break down into sorbitol and ethylene oxide. The sorbitol may increase the risk of diabetes as well as cell death, mitochondrial failure, and DNA fragmentation. The Hazardous Substances Data Bank of the US National Library of Medicine warns that sorbitol “is not to be injected.” But twenty times more ethylene oxide than sorbitol is produced, and it’s even more toxic.
Injected polysorbate 80 has also been shown to abruptly change heart function. A statement about a drug used to treat anaemia related to chronic kidney disease and chemotherapy warns: “Clinical studies have shown darbepoetin alfa (polysorbate 80) to increase the risk of serious side effects (eg, blood clots, stroke, heart attack, heart failure) and death in some cases. It has also been shown to shorten overall survival and/or increase the risk of tumor growth or recurrence in patients with certain types of cancer.” A very long list of side effects which “Applies to darbepoetin alfa: injection solution” is provided for consumers. However, just a few of them “usually do not need medical attention”!
Another problem is that polysorbate 80 can cause hypersensitivity reactions and anaphylaxis. And it is particularly risky in infants. Furthermore, its risk is increased when polymyxin B, another vaccine ingredient, is present.
An article by Joseph Mercola DO suggests it might cause infertility too. He informs us about “a Slovakian study published in the journal Food and Chemical Toxicology in 1993. The researchers injected female rats with Tween 80 (in 1, 5 or 10 percent aqueous solution), on days four through seven after birth. They discovered that Tween 80 accelerated the rats’ maturation, prolonged the estrous cycle, decreased the weight of the uterus and ovaries, and caused damage to the lining of the uterus indicative of chronic estrogenic stimulation. The rats’ ovaries were also damaged, with degenerative follicles and no corpora lutea (a mass of progesterone-secreting endocrine tissue that forms immediately after ovulation). Such severe deformities to the ovary can lead to infertility.” In his August 2013 newsletter, Dr Palevsyky mentions a British Medical Journal case report of ovarian failure in a 16 year old following vaccination with HPV vaccine (which contains polysorbate 80). The report advises: “This event could hold potential implications for population health and prompts further inquiry.” It will probably be used in US Vaccine Court as one piece of evidence that ovarian failure of two young sisters was caused by Gardasil HPV vaccine.
