A huge hat tip goes to Sallie O Elkordy, who asked if anyone has contradicting information about E. coli being an ingredient in two meningococcal vaccines, for bringing this to my attention. As readers can see from the below CDC Pinkbook of vaccine excipients and media, the two 2015 Meningococcal B vaccines Bexsero and Trumenba contain E. coli, so what can be expected from that ingredient being injected into the human bloodstream?
Trumenba [Pfizer] contains 0.018 mg of PS80 [polysorbate 80] and 0.25 mg of Al³+ as AlPO4 L [aluminum] http://www.fda.gov/downloads/BiologicsBloodVaccines/Vaccines/ApprovedProducts/UCM421139.pdf pp.6-7. Furthermore, in the package insert Description (pg. 6), this is stated: The recombinant proteins are extracted from the production strains and purified through a series of column chromatography steps. Again, what adverse reactions can manifest from those ingredients? Thimerosal is still in multi-dose vials of Menomune [Sanofi Pasteur] and formaldehyde is in Menveo [GlaxoSmithKline].
Readers are encouraged to do your research and homework regarding every vaccine’s ingredients/excipients. Here’s the link for all vaccine package inserts. Please study them carefully!
