QUESTIONABLE INGREDIENTS IN GLAXOSMITHKLINE’S SHINGLES VACCINE
Shingrix is an inactivated, genetically-engineered vaccine that does not contain a live virus like its competitor Zostavax.
The vaccine’s primary ingredients include glycoprotein E (gE)—a protein found in the varicella-zoster virus—mixed with
GSK’s proprietary adjuvant suspension called AS01. The latter consists of the saponin QS-21—a purified extract from
41
the bark of a soapbark tree native to central Chile (Quillaja saponaria Molina)—and an immune-stimulating fat called
MPL (3-O-desacy1-4’-monophosphoryl lipid A). The highly potent QS-21 adjuvant is used to stimulate a strong immune
response in lieu of using a live virus, but it is experimental and little is known about its mechanisms of cellular activa-
tion. Some researchers have reported uncertainty about QS-21’s potential toxicity and “undesirable haemolytic effect”

(rupturing of red blood cells and release of their contents into surrounding fluid) in humans. Shingrix also contains the

problematic surfactant polysorbate 80, associated with adverse effects on female reproduction and blood-brain barrier
permeability. 44
