A 🧵about 🧠problems after C19 💉
1. Neurological complications after first dose of COVID-19 vaccines and SARS-CoV-2 infection.
“There was an increased risk of Guillain–Barré syndrome and Bell’s palsy with ChAdOx1nCoV-19, hemorrhagic stroke with BNT162b2. ..An independent
Scottish cohort provided further support for the association between ChAdOx1nCoV and Guillain–Barré syndrome, there was a substantially higher risk of all neurological outcomes in the 28 days after a positive SARS-CoV-2 test including Guillain–Barré syndrome. Overall, we

Thyroid as a #target of adjuvant #autoimmunity /#infammatory syndrome due to mRNA‐based SC2 vaccination. #Vaccines contain #adjuvants which are not exempt from adverse efects and can #trigger the autoimmune/infammatory syndrome induced by adjuvants (#ASIA).
Multiple endocrine organs have receptors for ACE2.
mRNA of ACE2, the SARS-CoV2 receptor, is expressed in the thyroid cells.
ACE2 receptor is abundantly expressed by the thyroid. Elevated levels of proinflammatory cytokines could increase the expression ofACE2 on the thyroidgland.

Road to #Paxlovid#Pfizer#COVID19 new drug. pubmed.ncbi.nlm.nih.gov/34029993/
3CLpro inhibitors commonly target host proteases, which presents a potential liability for unexpected side effects.
Challenges : enzyme inhibition was only achieved in the absence of physiologically relevant reducing agents, and the reported antiviral effect in cells infected with SARS-CoV-2 could not be reproduced and was therefore suspected to be an indirect consequence of cell death.

The vaccines are failing against Delta Variant (DV).
All of us esp parents and teacher need to pay attention to the symptoms. Early treatment are the best, don't wait for the PCR. If a kid has symptoms,
get him out of school, put him in his bedroom with windows open. Early test: antigen test. Kids should not be vaccinated, give them Vit C Vit D, Zn, polyphenol supplements e.g. Quercetin. Aspirin for fever. Check aapsonline.org/covidpatientgu…
