Sift out the narrative BS and it looks like the injections exacerbate demyelination of CNS (aka MS)
"Here we report the clinical and MRI features of seven individuals who received SARS-CoV-2 mRNA vaccines and, within a few weeks of either the first or second dose, developed new neurologic symptoms and MRI findings consistent with active CNS demyelination."

MAYBE IT’S THE MERCURY (& ALUMINUM & GLYPHOSATE & PLASTIC & ...) but let’s start with mercury and heavy metals and *safely* get them out, and keep them out, of your teeth and tissue and nervous system.

THE CHRONIC INFLAMMATION TEST

AND MAYBE IT’S INFLAMMATION IN BLOOD FROM RANTES & THROMBOXANE A & ARACHIDONIC ACID & INTERLEUKINS ON FIRE & MYCOTOXINS LIKE CITRININ & EXCESS IRON & GLUTAMATE ...

CHRONIC INFLAMMATION RELATED TO PLATELETS (BLOOD) & “LONG HAUL COVID” (and mast cell activation/histamine and Lyme and so on)

GENETICS
The genetics involved (exacerbated by environmental toxins mentioned above) are TNF-a which I posted about earlier, SOD 1/2/3 which moves out superoxide, various variants in autophagy enzymes like AGT13 and ULK, CACNA1 (sensitivity EMF thru cellular calcium channels) and a few others associated with COX (COX inhibitors, non-steroidal anti-inflammatories, such as ASPIRIN).
You will also want to look at GLUTATHIONE RECYCLING and PEROXYNITRITE (when you wind up making the damaging ONOO - peroxynitrite - instead of nitric oxide.)
And you will also want to look at the RAAS (renin-angiotensin-aldosterone) pathways that rev up mast cells (that Holmes Cycle with our spike protein friend inserting himself into ACE2)
What we are describing here is post-injection inflammation which I am calling ‘COVID’ ... in quotes.
You will have to read between the lines.
The eyes-opened-wide health care sector speaks in code.

Above all, Covid showed how gullible human being are, and how easily they believe propaganda.

Biden doesn't need a misinformation governance board. He's already got one in charge of spreading misinformation. It's called the CDC.

TESTING ORGANIC ACIDS IN YOUR URINE (OAT)
(Urine is your filtered blood. This test looks for markers of gut bacteria and fungi in your urine, as well as indications of vitamin levels and compounds like oxalates and glutathione). The OAT is a snapshot, taken from one morning’s urine.). You will want to look at your test results alongside other information like your enzymes (DNA), salivary and urine pH, hair (or big toenail) mineral test, and other data.
ALWAYS ASK ‘WHY’? For example, you may have a high level of 4-cresol, a marker for the bacteria called Clostrdium dificil (C dif for short). Elevated C. dif can cause elevated levels of dopamine. Why do you have elevated levels of C. dif? In some postings above, on mercury, you will read that mercury can elevate levels of C. dif? Do you have high levels of mercury? If so, why?
(note that the presentation is based on ‘germ theory’ and references ‘killing viruses” which is impossible since they are not alive, and the ones he mentions have never been isolated/purified or met Koch’s Postulates. I am looking around for interpretation of OAT from terrain theory ...)

EXCESS DOPAMINE THEN CREATES OXIDATIVE STRESS (SUPEROXIDE, HYDROGEN PEROXIDE) WHICH DEPLETE GLUTATHIONE
And now because you are short on glutathione, you can’t clear toxic compounds and drugs and that in turn can cause toxicity and neurological damage. If you have variants in the enzymes involved in clearing oxidative stress (like SOD, CAT, GSH) then there is even more potential for toxicity.

YOU SAY TOXIN, I SAY TOXICANT
I have been using the words incorrectly all along!

TRYPTOPHAN & QUINOLYTIC ACID & NEURO INFLAMMATION.
Here 👇👇👇👇Brandon Vermeire walks through the biochem of quinolytic acid which is assessed in an organic acids test. You can take an amino acid like tryptophan with all good expectations that it will turn into serotonin and melatonin ... but things can go awry, and you might be making quinolytic acid instead. Which would really stink since it contributes to brain (neuro) damage, as Brandon describes. I have posted previously a list of Brandon's brain inflammation markers and how to test for them.

Quinolytic acid revs up glutamate and glycine which are (ahem) two amino acids comprising glutathione (the third is cysteine, aka NAC)
Obviously you can do your own search on glutamate and NMDA but here is a quick rundown of neurodegerative illnesses linked to NMDA
Alzheimer's disease
Amyotrophic lateral sclerosis (ALS)
Huntington's disease
Parkinson's disease
Epilepsy

Other central nervous system conditions with suspected NMDA receptor involvement include:
Fibromyalgia
Chronic fatigue syndrome
Migraine aura
Some types of headache
Anxiety
Depression
Schizophrenia
Post-traumatic stress disorder
Obsessive-compulsive disorder
