Editing Spike as a superantigen

=== COVID vaccine | Perimyocarditis ===

A Hong Kong group used the Pfizer vaccine on mice.  When the vaccine was injected intravenously (rather than via the intramuscular route), the mice developed perimyocarditis.  https://academic.oup.com/cid/article/74/11/1933/6353927

Female and male Balb/c (substrain OlaHsd) mice were used.

'''Dosage''':  COVID-19 mRNA vaccine (BNT162b2 lot number 1B004A, BioNTech, Germany) dose of 0.25 µg per gram of body weight was injected (about 5 µg in 50 µL per mouse; dose according to an immunogenicity study).  A Pfizer dose for a lightweight 40kg human would be 30 µg, or 0.00075 µg per gram of body weight.  The dosage used in the animal study was roughly 333X that of a human dose.

=== Gardasil HPV vaccine | HPV vaccination associated neuro-immunopathetic syndrome (HANS) ===

* https://autoimmunity-network.com/articles/Maria%20Biobody.pdf - Mice vaccinated with Gardasil and aluminium adjuvant only fared worse on a forced swim test.  Phospholipid supplementation can attenuate vaccine-induced depressive-like behavior.

=== COVID vaccine | Multiple organ failure ===

* A [https://igorchudov.substack.com/p/fully-vaccinated-gorilla-dies-of?s=r Substack article] speculates that a Western lowland gorilla died from COVID vaccination.

=== Hepatitis B vaccine | SLE / Lupus ===

* https://sci-hub.se/https://doi.org/10.1016/j.jaut.2014.06.006 - Mice were immunized with Hep-B vaccine, aluminium adjuvant, or the control injection (phosphate-buffered saline).  SLE-disease resulted for the vaccine and alum group.  Immunization with either HBVv or alum affected blood counts, neurocognitive functions and brain gliosis.  Various biomarkers were examined, though measurements had mixed results.

=== Multiple vaccinations | ASIA syndrome ===

ASIA syndrome - commercial sheep were given repeated vaccinations (thiomersal/thimerosal, aluminium salts, antigen) https://sci-hub.se/https://doi.org/10.1007/s12026-013-8404-0

=== SARS-CoV-2 spike protein | Acute COVID ===

Biancatelli, Solopov, et al. (in a group that included Paul Marik) tested SARS-CoV-2 spike protein on humanized mice and wild-type mice (https://doi.org/10.1152/ajplung.00223.2021).  The genetics of the Κ18-hACE2 mice were manipulated to overexpress human ACE2 receptors.  The humanized Κ18-hACE2 mice exhibited a more severe form of COVID-19 symptoms.

=== Aluminium adjuvant | Gulf War Illness / Motor deficits / Cognitive deficits ===

* https://link.springer.com/article/10.1385/NMM:9:1:83 - An animal model for examining the potential neurological impact of aluminum hydroxide, squalene, or aluminum hydroxide combined with squalene was developed.  Behavioral testing showed motor deficits in the aluminum treatment group that expressed as a progressive decrease in strength measured by the wire-mesh hang test (final deficit at 24 wk; about 50%). Significant cognitive deficits in water-maze learning were observed in the combined aluminum and squalene group (4.3 errors per trial) compared with the controls (0.2 errors per trial) after 20 wk.

=== Other models ===

Mother models such as squalene, aluminium adjuvant, other vaccines, etc. etc. likely exist.

=Superantigen theory notes=

https://sci-hub.se/https://doi.org/10.1016/0882-4010(87)90003-9 - In the TMEV virus, inbred mice can be more susceptible or more resistant to the virus.

=== HPV Gardasil vaccine ===

https://www.nature.com/articles/srep36943 - This Japanese group demonstrated an animal model for the HPV vaccine using pertussis toxin to skew the autoimmunity towards neurological phenotypes that include low responsiveness of the tail reflex and locomotive mobility.  They compared HPV + pertussis to MOG (myelin oligodendrocyte glycoprotein) antigen + pertussis toxin.

=== Kawasaki disease (similar to MIS-C) ===

"semi-therapeutic HBOT significantly alleviated the progression of EAE, at least, via the suppression of Th17 response, the downregulation of CD4 T helper cells expressing GM-CSF or TNF-α, and the boosting of immunomodulatory IL-4 or IL-10-expressed CD4 T cells in the CNS lesions. Conclusively, HBOT attenuated EAE through the modulation of T cell responses in an earlier stage"

= Priority research questions =

* Are existing therapies effective?
* What repurposed drugs are effective for treating long haul?
* Is there some way to avoid long-lasting worsening from the best treatments?  Is there some test that can predict serious adverse reactions to treatment?
* Are drug combinations useful for treating long haul?

* Do humanized ACE2 receptors matter in the animal model?

=== Research questions that matter less than they first appear ===

* Are there treatments that are effective in animal models but not in humans?  →  The practical workaround is to first test repurposed drugs with excellent safety profiles.  If these drugs fail in humans, the downside is very low.

=== Less important research questions ===

* Do all the spike protein vaccines cause vaccine injury in animals?
* Does the animal model exhibit stereotypical symptoms such as fatigue and post exertional malaise?
* Why are some people non-responders to treatment?
* Does immunosuppression cause long-term harm?
* Do COVID vaccines cause stillbirths?
* Is the same animal model also viable for Long COVID research?  (The advantage of vaccine-induced 'Long COVID' is that no biosafety level 3 lab would be required, saving money.  However, obtaining mRNA vaccines may be difficult.)
* Do chronic illness patients react badly to other vaccinations (e.g. flu), contrast dye, etc.?
