A new peer-reviewed Stanford University Department of Pathology study published in Cell and funded by the National Institutes of Health, the Bill and Melinda Gates Foundation, and other institutions suggests that recipients of the Pfizer-BioNTech vaccine for COVID were found to have at least as much spike protein in their blood as unvaccinated people who were infected by the virus.
Questions About Spike Protein
The biodistribution of mRNA-based COVID vaccine has become a longstanding issue for researchers and especially for patients claiming vaccine injuries. Among the main issues raised by skeptics of mRNA-based COVID vaccines is the behavior of the spike protein antigen, which some researchers claim is cytotoxic.
Plasma Compared Across Different Cohort Groups
The researchers compared several batches of plasma from different patient groups. The research hers took plasma from 530 hospitalized patients with moderate to severe COVID symptoms was compared to plasma from 87 patients with “mostly mild” symptoms, to plasma from 196 vaccinated Mongolian patients and to plasma taken from 37 “healthy” individuals prior to the pandemic (as a control group).
Finally, the researchers also examined the saliva of 20 healthy individuals.
Lymph Node Biopsies Also Compared
The researchers also took lymph node biopsies from mammograms – seven from patients after they had two doses of the Pfizer COVID vaccine, three from patients were unvaccinated and seven from patients who died with COVID symptoms, which they compared to a control group of biopsies taken from deceased patients prior to the pandemic.
