People keep asking what sag means. SAG means superantigen. It is a piece of protein that activated t cells nonspecifically. those t cells harm adjacent tissues like the brain. jstor.org/stable/24939021

Delta has changed the game. I used to think a 70% community vaccination level would be sufficient to protect children in schools without their vaccination
Onward transmission of Delta among vaccinated in Israel caused infection of the youth. nature.com/articles/d4158…
Therefore, these calculations and practices must be reassessed. Reasonably, Israel is moving to vaccinate their youth. Ignoring this changed metric comes at the cost of more confusion. reuters.com/world/middle-e…
So: 1) via breakthrough, Delta has upset the argument youth are protected by adult vaccination 2) Onward transmission is indubitably more frequent 3) Physiological consequences of breakthrough infection by Delta have yet to be assessed. washingtonpost.com/opinions/2021/…
In cases where people have been vaccinated and then had a breakthrough case and developed anosmia-
Do they have autoantibodies to neurological proteins or brain T cell infiltrates or hippocampal changes like in the UK Biobank study? upi.com/Health_News/20…
2/ These studies correlate and illustrate the brain changes from Covid-19. This study showed smaller areas in gustatory and memory regions of the brain of people after Covid. medrxiv.org/content/10.110…
3/ sadly, these changes were seen even in mild cases. Another study out of Stanford showed that T cells infiltrate the brain in Covid-19. Worrisome- this can cause encephalitis and brain damage. nature.com/articles/s4158…
If you leave critical decisions up to charlatans and people that overextend their expertise you end up with repeat waves and reinfections like in India when challenged with new variants.
Infected should have a boost with mrna for variant protection.
studies come out all the time showing this. Only herd immunity apologists who called it wrong and the recklessly ignorant will maintain infection confers better protection.
In regard to the cleveland clinic preprint: Charlatans that cannot contextualize a study with its environment by grasping temporal shifts in context (aka a delta, P1, or b1351 driven encroaching wave) should not be allowed near policy.
When controlling for age, body habitus, and other variables, people who had covid had sizes of key brain structures 4 standard deviations below average.
These changes were not found to be different whether one was hospitalized or not.
The one metric where size increased post covid- ventricle volume- is a good marker for loss of brain matter. This usually increases with age.
And before people tell you this was unexpected- no. This was predictable. Furin cleavage sites confer neurotropism and this was my primary concern with the virus. With the knowledge it had a Sag, the situation appeared more dire. Downplayers are culpable.
