From your link which referenced William N Voss paper but it was generally a dead end. Other then the fact they use
nineteen different antigens the reason they don't use ONE is because they said they don't know what covid is. They also don't tell us what the pseudovirus they used.
I looked myself found a few pseudovirus though I don't know which one they used for the mRNA injections.
This one is Streptococcus (bacteria) though they didn't say which one.
https://www.raybiotech.com/recombinant-sars-cov-2-s1-subunit-protein-rbd/ This report has two different researchers using Papillomavirus (likely used in mRNA for their pseudovirus) the other is using HIV
https://www.news-medical.net/health/What-is-a-Pseudovirus.aspx The researchers using HIV is the closest but I have no idea why they don't know what covid is after two years.
Let me help you out:
Covid is Plasmodium Yoelii parasite and Simian immunodeficiency virus (SIV) from this paper
COVID-19, SARS and Bats Coronaviruses Genomes Peculiar Homologous RNA Sequences Jean Claude perez & Luc Montagnier
https://www.researchgate.net/publication/342926066_COVID-19_SARS_and_Bats_Coronaviruses_Genomes_Peculiar_Homologous_RNA_Sequences_Jean_Claude_perez_Luc_Montagnier Plasmodium Yoelii is the antigen for Covid-19 two spikes. That means they need to use for their pseudovirus some kind of Plasmodium family (parasites) as their antigen.
given they are using bacteria based epitope rather then the correct antigen IE:parasite. Their vaccine can't work.
