Type 1 diabetes mellitus caused by COVID-19 mRNA vaccination: A case report and literature review of 17 published cases
-> https://pmc.ncbi.nlm.nih.gov/articles/PMC11447533/

"New-onset type 1 DM has been reported after COVID-19 mRNA vaccination. Clinicians should maintain a high index of suspicion and pursue early testing for the same to reduce adverse outcomes and improve long-term prognosis."

Otitis media with ANCA-associated vasculitis following COVID-19 mRNA vaccination -> https://pubmed.ncbi.nlm.nih.gov/39344100/
"The pathogenesis of adverse events following COVID-19 vaccination are still unclear. This report has indicated that ANCA-associated vasculitis can be related to COVID-19 mRNA vaccines. As our knowledge of autoimmune disease developing after COVID-19 vaccination is still in the accumulation phase, it is relevant to amass such case reports and use them for assistance in diagnosis in the future."

Secondary T-cell deficiency (particularly affecting CD4 T cells) & chronic spontaneous urticaria after COVID-19 vaccination: https://www.jaci-global.org/article/S2772-8293(24)00135-8/fulltext
- "The precise mechanism underlying this occurrence remains unknown, although there have been numerous reports highlighting the association between COVID-19 vaccination and autoimmune disorders."
- During his treatment period, he received another COVID-19 vaccine, got COVID-19, and the doctors administered additional vaccines (pneumococcal conjugate vaccine 13-valent, herpes zoster vaccine, pneumococcal polysaccharide vaccine 23-valent, and diphtheria, tetanus, and pertussis vaccine) "to prevent further complications."

"The exact mechanism underlying the development of UV following vaccination remains unclear."
"Accumulation of further cases and research is required to investigate the clinical course and underlying mechanisms of vaccine-induced UV."

Matrix metalloproteinase-9 (MMP-9) is significantly elevated in the serum of long COVID patients:
https://pmc.ncbi.nlm.nih.gov/articles/PMC11472557/
- Microglia release MMP-9 when stimulated by SARS-CoV-2 Spike protein
- "MMP-9 can disrupt the polysaccharide scaffolding of the brain matrix & digest tight junction proteins, thus disrupting neuronal connectivity. MMP-9 can cause vascular inflammation and increase blood brain barrier (BBB) permeability"
(The COVID-19 vacciantion status of the study participants was not taken into account)
(An increase in MMP-9 has been documented in patients with systemic inflammation following COVID-19 vaccination: https://journals.lww.com/jcma/fulltext/2023/09000/elevated_serum_levels_of_t_cell_immunoglobulin_and.8.aspx)

Important discovery regarding the special thrombi (clots) observed by various embalmers and pathologists: staining with the sensitive amyloid dye Thioflavin T (ThT) is positive, i.e. they are probably amyloid-like thrombi!
Here are fluorescence microscopy images published by Richard Hirschman (@r_hirschman) and Greg (@Greg21143362):

The fact that these clots stain positive for ThT is not good news, as it indicates that these clots are special and cannot be easily dissolved by the body through fibrolysis.
Presumably, these clots are also full of neutrophil extracellular traps (NETs), as has already been shown for amyloid-fibrin microclots (which are probably the smaller form of these macroclots) [1]:
[1] https://www.researchsquare.com/article/rs-4666650/v1

(7/n)
Systematic studies are now needed to investigate these large clots using ThT-based fluorescence microscopy and, ideally, staining of NETs, as well as quantification of the amyloid fibrin microclot concentration (and size distribution) in plasma.
This would actually be a topic for a @Nature or @ScienceMagazine paper – which research group dares to tackle this hot and difficult topic?
For an earlier analysis of these clots, see my older post: https://x.com/DrJohnB2/status/1807188321665212922

In Germany, there is now a laboratory where you can get tested to see if you have components of the mRNA vaccine in your body (blood, tissue samples, etc.).
-> https://inmodia.de/en/

The Institute of Molecular Diagnostics (INMODIA GmbH) offers detection of:
- Spike protein
- ‘Vaccine mRNA’ (modRNA)
- Contaminating DNA (plasmid DNA)
These components can be detected in the following sample materials:
- Tissue samples (biopsy or autopsy materials, fixed or unfixed)
- Blood plasma
- Cerebrospinal fluid
- Immune cells from whole blood or cerebrospinal fluid

It's great that a service like this is now available!
I expect that many more such laboratories will be opened worldwide in the near future, or that existing laboratories will start offering these services...

Syncopes, paresis & loss of vision after COVID-19 mRNA-based vaccination & SARS-CoV-2 infection: https://link.springer.com/article/10.1007/s15010-024-02439-y
- "6 h after vaccination, the patient developed severe cephalgia & dizziness lasting for several days"
- "Spontaneous syncope occurred 20–30 times over the following 2 weeks. Even though the syncopes disappeared, the patient continued to observe irregular heartbeats. ... he reported new onset of fatigue, brain fog, acral paresthesia, paresis of forearm extensors and Mm. quadriceps femoris, disseminated fasciculations & urticaria in the weeks following the vaccination"
- "143 days after vaccination, the patient suffered a PCR confirmed SARS-CoV-2 infection, and the symptoms experienced after vaccination exacerbated"
- "The details on the mechanisms underlying adverse side effects caused by mRNA-based vaccines remain unclear"
- "Further mechanistic research assessing the pathologies that may trigger mRNA vaccine-associated symptoms are urgently needed"
