- 1 It's been shown that 2P-LNP spike is taken up by cells then repackaged into exosomes (Bansal). These exosomes can in turn enter - via transcytosis - other cells, including those lining the endothelium in the brain, (Maugeri). Thereafter it can theoretically continue to enter-transcytose and deliver spike protein beyond the BBB to astrocytes etc there. Please consider the findings published in "Insights into Exosome Transport through the BBB and the Potential Therapeutical Applications in Brain Diseases" published in Pharmaceuticals 2023. Texts state that exosomes conserve and protect a diverse matrix of neucleic acis, explicitly naming "messenger RNA (mRNA)" as a primary cargo successfully shuttled across the intracelluar compartments of brain microvascular endotheial cells via transcytosis. To what extent and how does this add evidential weight? + a private exchange

How could mislabeling spike source change “viral reservoir” conclusions?
The short version: mislabeling the spike source turns a "viral reservoir" finding into a "vaccine product persistence" finding, and the evidence for the second is stronger in the studies that have been done.
The 2026 chronic infection study [1] found convergent intrahost evolution in 14 mutation patterns across the genome, including deep-lung tissue adaptations. That is real evidence that the virus can persist in some people. But it studied 3,332 chronic infections and looked at viral RNA, not spike protein. It does not tell you what the spike protein studies are actually measuring.
The 2024 B cell profiling study [2] shows that mRNA vaccines elicit memory B cells against wild-type spike that can broaden after Omicron infection. That means the immune system treats vaccine-derived 2P spike and infection-derived WT spike as similar enough to cross-react. An antibody assay cannot reliably tell them apart. When a tissue biopsy finds "spike" in a vaccinated person, the assay is blind to which version it found.
The 2024 critique of N1-methylpseudouridine substitution [3] calculates that the modified mRNA encodes a spike protein with 728 base substitutions and altered molecular weight. The 2P spike is not just a stabilized version of the wild-type spike. It is a different molecule. The body processes it differently, and the assays used to detect it do not distinguish it from the viral version.
The 2022 eLife study on vaccine-induced COVID-19 mimicry syndrome [6] shows that cryptic splice sites in adenoviral vaccine vectors produce secreted spike variants lacking the transmembrane domain. These truncated spikes circulate freely and can be detected in tissue long after vaccination. A study that finds "spike" in tissue and calls it a "viral reservoir" has not ruled out that it found these vaccine-derived fragments instead.
The 2023 pH-dependent electrostatic study [15] shows that Omicron spike binds ACE2 more strongly in acidic nasal environments but less so in neutral blood. The 2P spike has different electrostatic properties. The assays that detect spike protein do not account for these differences.
My call: the "viral reservoir" conclusion in any study that used a non-specific spike assay on vaccinated subjects is unsupported. The evidence points to vaccine product persistence as the more likely explanation for the spike detected. Confidence: high.
