Covid vaccine and multiple sclerosis

Covid-19 vaccination can induce multiple sclerosis via cross-reactive CD4+ T cells recognizing SARS-CoV-2 spike protein and myelin peptides

Both natural infection and the mRNA based vaccinations can be accompanied by transient autoimmune phenomena,

or onset of autoimmune diseases.

Objective

Two cases of multiple sclerosis (MS),

with clinical and new radiological signs,

beginning in close temporal relation to spike (S) protein mRNA based vaccinations.

Aim

The onset of MS in these two cases is very likely caused by CD4+ T cell clones,

that cross-recognize SARSCoV- 2 S protein,

from myelin proteins.

Method

Spike specific CD4+ T cells from peripheral blood,

and CD4+ T cells from CSF sample were isolated,

then underwent autoantigen screening test.

(An endogenous antigen that stimulates the production of autoantibodies)

A list of well-known MS related autoantigens,

Result(s)

Self-reactive T cells were detected from Spike specific T cell population,

also showed reactivity to MBP, MOG, (Myelin oligodendrocyte glycoprotein) peptides PLP peptide pools.

Multiple sclerosis and myelin basic protein: insights into protein disorder and disease

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8810476/

Myelin basic protein (MBP) is an abundant protein in central nervous system (CNS) myelin.

MBP has long been studied as a factor in the pathogenesis of the autoimmune neurodegenerative disease multiple sclerosis (MS).

MS is characterized by CNS inflammation, demyelination, and axonal loss.

Finally,

we found proinflammatory T cell clones,

that recognize both Spike protein and immunodominant Myelin basic protein peptides,

and Myelin oligodendrocyte glycoprotein (MOG) peptides, which have previously been implicated in MS.

Conclusion(s)

Detailed studies of both peripheral blood, and CSF derived CD4+ T cells show that the onset of MS in these two cases is very likely caused by CD4+ T cell clones that cross-recognize SARS-CoV-2 S protein derived peptides and peptides derived from myelin proteins, which have previously been implicated in MS.

New diagnosis of multiple sclerosis in the setting of mRNA COVID-19 vaccine exposure (January 2022)

https://pubmed.ncbi.nlm.nih.gov/34922126/

Multiple sclerosis (MS) with onset in the setting of acute SARS-CoV-2 virus infection has been reported,

and reactivation of MS following non-mRNA COVID-19 vaccination has been noted,

There have been three reports of newly diagnosed MS following exposure to mRNA COVID-19 vaccine.

The association cannot be determined to be causal,

We report a series of 5 cases of newly diagnosed MS following recent exposure to mRNA COVID-19 vaccines.

Latency from vaccination to initial presentation varied.
Neurological manifestations and clinical course appeared to be typical for MS,

including response to high dose steroids

Conclusion

Acute neurological deficits in the setting of recent mRNA COVID-19 vaccine administration may represent new onset multiple sclerosis.

Hold a parliamentary vote on whether to reject amendments to the IHR 2005

We are concerned that Parliament has not discussed and will not have a say on the 307 proposed amendments to the International Health Regulations,

AND the amendments to 5 Articles of the IHR that were ADOPTED by the 75th World Health Assembly on 27 May 2022.
