Kids need to be vaccinated. Why?

Because things can go horribly wrong with infection, and infection is a process with proof of continuation.

Let's look at a few coronavirus examples and how they relate to cov2 🧵
Feline Infectious Peritonitis has a Furin Cleavage Site *EQUIVALENT* to Cov2

Fip in cats is notably a fatal, incurable, chronic illness, which interestingly requires a form/precursor of remdesivir to cure.

This must be given for 100 days.
So the cats bodies mount a response to the virus, but it is able to hide out and mutate in some, and cause vasculitis and neuroinflammation.

Sound familiar? vet.cornell.edu/departments-ce…
Some immunologists theorize there could be a neural reservoir for cov2

In a chicken coronavirus, a similar Furin Cleavage Site enabled neurotropism which engendered neural symptoms and more illness
pubmed.ncbi.nlm.nih.gov/32057769/
Here is a nice review of the neurological/encephalitic models of neurotropic viruses as they relate to cov2

We do not know if there will be a later manifestation

If it is like measles it would be tragic
ncbi.nlm.nih.gov/pmc/articles/P…
I'm not a virologist, but I try to extrapolate what I see and compare it to pathogens with other features.

Basically this is
✅neurotropic
✅has a superantigen
✅potentially chronic
So when I think of bad hombres in the brain, I think of
✅measles
✅HIV related dementia
✅Rabies
✅OC43
So thank goodness we are not seeing anything like hydrophobia despite rabies and cov2 being superantigenic, so we can set that aside.

However, OC43 has many of the same neurotropic features

but cov2 also has a superantigen, as does HIV
news-medical.net/news/20200504/…
So if I were to imagine, I would say we will see an uptick of cov2 related neuropathology in the long term

How bad?

That's for the fates to decide.

There is ample bioplausibility for tragedy, though.

People seem to equate lockdowns with a 0 covid tolerance approach

I recall lockdowns are used in a "herd immunity" approach just before hospitals are overwhelmed.

In fact, "herd immunity" pursuant countries have arguably spent the most time in lockdown
The pursuit of herd immunity is probably why schools are used by some countries for a populational "natural" immunity

Infected children are less frequently hospitalized (1%). However, they are also less likely to seroconvert

Children do, however, infect young parents
In fact, you can see this pattern of children infecting parents from schools.

This could be why there are right-wing lobby groups for no masking.

They want to achieve an infection-based immunity period all the more quickly.

This is important:

B.1.617 has mutations that may *enhance* pathogenesis

A mutation at P681R in combination with L452R and E484Q significantly increases syncitia formation

This is when the cells fuse together, and it's linked to fatal disease.
2/ The Gupta lab found the mutations L452R/E484Q/P681R together significantly increase Syncitia formation.

This is a function of the polybasic cleavage site. Syncitia formation is linked to fatal diseasehttps://www.biorxiv.org/content/10.1101/2021.05.08.443253v1
3/ Syncitia are a way the virus kills T cells

This paper in Cell Death and Differentiation discusses how Syncitia internalize T cells in order to kill them

This thread is in regard to the concerning things about Cov2.
I owe the idea to @LgSOS

To start, we have the neuroinvasion seen by @ericsongg @VirusesImmunity et al. rupress.org/jem/article/21…
2/ There is also a predominant symptom of anosmia (loss of sense of smell).

This anosmia is seen as unlikely to be from mucosal/nasal swelling ncbi.nlm.nih.gov/pmc/articles/P…
3/ Interestingly, a few case reports have emerged of Parkinson's following infection.
thelancet.com/journals/laneu…
A worrisome correlate may exist as seen by this preprint: monkeys had precursors of Parkinson's after infection, called Lewy Bodies biorxiv.org/content/10.110…

1/This is concerning.

A human endogenous retroviral protein is being induced in lymphocytes in Covid-19.

This is the same HERV implicated in Epstein Barr's association with Multiple Sclerosis
thelancet.com/journals/ebiom…
🧵
2/ Cov2 is eliciting the same human Endogenous retrovirus as Epstein Barr, and the expression increases with T cell differentiation 🤯 Image
3/ Interestingly, Epstein Barr virus will "awaken" parts of an endogenous human retrovirus-

this is an ancient virus lurking in our DNA

It functions like a superantigen and stimulates lymphocytes.

I've not seen so much power and simplicity in data for a long time.

Cov2 is generating T cell escape epitopes, and there may be a dominant selection for a nucleocapsid site for B*27:05
biorxiv.org/content/10.110…
🧵 1/
2/ The authors show a number of mutated peptides/variants that cause partial or complete loss of T cell reactivity for certain HLAs
3/ In my opinion, there can be a degree of selection against T cell epitopes when T cells are being used to react to virus- the situation where one has T cell memory but no sera. I think I mentioned this exact scenario before @MonicaGandhi9?

On the contrary, we should worry about variants "escaping" CD8+ immunity, especially if one has HLA:24

I am surprised- maybe we are awaiting publication? @NahasNewman

As of yet this sort of escape has been mostly theoretical. biorxiv.org/content/10.110…
When we lose CD8 reactivity, we lose our ability to cull infected cells. 😱

Something we were promised so frequently would not happen, but it did! @zeynep
They were warned in a light way, but it didn't get through 😔

This is my biggest fear manifest, and what did the AIER/Pandata/GBD crowd do? they passaged the virus in schools per Azar 😰
