I haven't written much about SARS-CoV-2 this year. It's still out there, despite the television news not really mentioning much of anything any more. Today, I wanted to share some tidbits that are interesting or worrying, while simultaneously avoiding my Doom Bingo 2025 topics. I'm also avoiding a lot of old 2022 studies that showed persistent infection in the brain and various kinds of physical damage in the brain after infection. I tried to keep these links a lot more "fresh" and recent.

Click to see a little of the bad news in no particular order...

The good news? There is some.

Click to read the proverbial silver lining...

  • This pre-print makes some interesting claims. Researchers found damage to the brainstem and cerebellum that might explain a variety of Long Covid symptoms. Notably, "While viral genetic material was detectable, infected neurons were not observed." This observation gives hope that we can become infected and sometimes not develop persistence within the brain. It might be imported from other areas of the body instead, maybe tissue without immune privilege, so the ongoing infection could eventually be cured. Within the downloaded PDF of the full article, they suggest that the virus damages the immune system, resulting in auto-immune problems that affect these outcomes in the brain, although these details are well above my level of understanding.
    "Brainstem Reduction and Deformation in the 4th Ventricle Cerebellar Peduncles in Long COVID Patients: Insights into Neuroinflammatory Sequelae and “Broken Bridge Syndrome”

  • This study offers another kind of hope. "Here we demonstrate extensive endothelial cell (EC) death in the microvasculature of COVID-19 organs. Notably, EC death was not associated with fibrin formation or platelet deposition, but was linked to microvascular red blood cell (RBC) haemolysis." As I interpret it, red blood cells are "jumping on a live grenade" to save you from circulatory system damage, and these kinds of clots might respond to new drugs that current blood thinning drugs don't help. That's good news too, despite the macabre horror of it.
    "Ischaemic endothelial necroptosis induces haemolysis and COVID-19 angiopathy"

  • This study notes that "SARS-CoV-2 infection is known to cause changes in the T cell compartment, including differences in expression of receptors associated with exhaustion. While immune responses to infection and vaccination are not equivalent, in the eyes of the public, this concern of immune exhaustion after infection can carry over to vaccination." They found that repeat vaccination does not lead to T-cell exhaustion. That finding is good news. I've mentioned before that spike protein (whether virus or vaccine) carries its own dangers, but at least immune system reduction doesn't seem to result from vaccination, just infection.
    "No evidence of immune exhaustion after repeated SARS-CoV-2 vaccination in vulnerable and healthy populations"

Sorry, that's a lot of information, even after I deleted half a dozen articles that I included on the first draft. :(

I still mask around other people. No matter how many times you've had COVID, it's better not to get it even one more time. Stay safe out there.

Long time readers here will learn nothing new in this very important article, but it is validation of what I have been warning about for years. Thanks to [personal profile] andrewducker for finding this gem. A doctor from the Icahn School of Medicine at Mount Sinai does a radio interview with CBC (Canadian Broadcasting Corporation). The doctor doesn't mention blood clots or T-cell infection but does forcefully confirm the following details:

  • persistent infection
  • persistent infection because immune privileged tissue like the brain gets infected
  • immune system damage
  • T-cell exhaustion
  • failure to suppress other diseases because of immune damage
    (which is essentially my Doom Bingo 2025 topic of C-AIDS but without using that terminology yet)

"There is no such thing as a COVID infection without consequence"
- https://www.cbc.ca/radio/quirks/beyond-long-covid-1.7485888,
"Beyond long COVID — how reinfections could be causing silent long-term organ damage"

I recommend hitting the play button near the top of that article and listening to the 20-minute interview. The text summary is good and covers the major topics, but it is incomplete. I like that particular quote the most. Stay safe out there. Keep masking, at least until all indoor spaces are well sanitized with filtration. I still need to send this info to my city, county, state, and national representatives.

An important overview paper about SARS-CoV-2 was published from The Medical Journal Of Australia online yesterday. It cites a lot of other papers, summarizing what's known about some of the issues I've been warning about here for a while. It focuses on things like immune dysregulation and viral persistence. This article has a long title with a bit of hope in it: "Towards a cure for long COVID: the strengthening case for persistently replicating SARS-CoV-2 as a driver of post-acute sequelae of COVID-19". Note, however, that it doesn't mention virus in neurons as another (non-curable) method of persistence. It only mentions the 2 methods of persistence (gut, and bone marrow/immune system) as potentially curable paths of persistence.

As always, I encourage everyone to keep masking. I do it myself every time I'm around other people.

I've decided to do something different in 2025. I know that even when restricting my doom-and-gloom posts to Moody Monday, that's still a lot of negativity that nobody needs in trying times. So I'm going to try transforming it into something almost "fun" for next year.

Near the end of 2024, I intend to post my Doom Bingo 2025 card. I will have each square with a topic that I expect to appear in 2025 as "Something Bad That Happens". I might even include some links for why I predict it will appear in the course of the year. During the year, however, I will not post about that topic. Really! Instead, as evidence piles up, I'll keep a folder of news clippings that I can use in December 2025 to determine if I "win" the bingo card for that year.

Now, I may post tangent topics, like helpful things to do to prepare for the troubles. I won't, however, post warnings any more. The time for warnings is over. Either my sense of trends is right or wrong. A Bingo game might make even bad news seem less traumatic. If nothing else, it'll keep this blog a little more like it used to be in the old days, focused more on interesting things to learn or do, or the fun intersection between many topics.

So, stay tuned. My planned Doom Bingo 2025 card will show up here soon. :) Finally, some relief from the stressful topics.

I am Novavaxed!

After 2.5 years without any boosters, I am finally vaccinated again. I got the single injection (no follow up injections needed) in my left arm almost 2 hours ago. It took several tries yesterday to schedule a Novavax vaccine appointment. I had no luck after contacting my walking-distance medical clinic, or the clinic on a bus route south of me, or at Walgreens (despite the Novavax website's "vaccine finder" saying they offered it). Finally, I logged into the CVS website, and they had Novavax as an option. I scheduled immediately for the next morning, today. Normally, today is a work day for me, but I have today off so I can work Friday instead, part of the accommodation I'm making in order to mentor a new employee.

On the walk to the bus stop this morning, I passed many houses with frost on the yard lawn. It finally got that cold here in Minneapolis last night. On the way back... I had not just one but TWO buses just keep driving right past me at full speed, while I sat there patiently at the bus bench. I finally got up and walked to a more common bus stop. I caught the next ride home successfully.

Important news about Novavax and why I waited 2.5 years to finally get it:

  1. I mentioned back in 2022 that Novavax included the S1 and S2 spike proteins of SARS-CoV-2. The other vaccines include only S1, which mutates quickly. In theory, my immune system should better protect me against future mutations if it knows the slow-moving target of the S2 spike protein. In theory.

  2. In addition, the big news this weekend is that researchers may finally know why protection against COVID wanes so quickly. This article explains that the position of the spikes on the native virus (and most vaccines) is too far apart for certain immune B cells to "lock on" and establish the long term memory that we need, so our short-term immune memory fades quickly and we're left much less protected. The article notes that the "Novavax COVID-19 vaccine approved in the United States and some other countries uses insect cells to produce spikes that link together and form “rosettes,” which might offer tighter spacing of the protein and therefore durability benefits". That's big news. Now, of course, the race should be to create new vaccines with the spacing of spike proteins that helps our immune system to remember these proteins for the long term. In theory, Novavax is currently better than other vaccines at providing longer term protection. In theory.

Of course, we also know that the spike protein alone causes blood clotting, so any exposure to it can potentially offer side effects. Still, though, it is much, much better to get exposed in limited duration to a vaccine rather than a potential lifetime exposure to the self-replicating virus itself, if it establishes persistence in our bodies. Barring specific contra-indications, I still strongly recommend vaccination. And masking. And distancing. And air filtering. I'll write more in a future Moody Monday post about the good reason for continuing precautions.

Stay safe out there.

a little good news

There's too much going on in the world and in my area of it, so today I'll share only Good News.

The first week of school has ended, and the pace of work is finally slowing. The high point was a long ticket where the phone caller said, "Don't leave me!" as I tried to exit politely after solving the main issue for them. By the end of the call, I helped a 75-year-old woman with signing up for her very first course at the university. It's a nice reminder that I, too, might someday return to college.

I've had a broken screen on my Pixel 4a phone for several years. A few days ago, it finally started causing problems when it wouldn't recognize touches on the screen to unlock it. I need it a few times each day for multifactor authentication at work. Today, since I didn't work due to USA holiday, I rode the bus to Best Buy in Roseville to buy a new Pixel 9 and switch my phone SIM card to it. It's up and running again, although not everything is reconnected. Among the first things to reconnect was the multifactor authentication. It was an expensive purchase but definitely an improvement over my last phone. Bonus 1: I learned that there's a single bus route (no transfers!) that goes straight from my area to that distant shopping area. Bonus 2: I saw during the round trip not just 1 but 2 people in masks!

The big news is this: Researchers might have found what causes the clots by SARS-CoV-2. I mentioned last year that the spike protein seemed to be the culprit, but it wasn't clear why. Now, this new research says that "fibrin binds to the SARS-CoV-2 spike protein, forming proinflammatory blood clots that drive systemic thromboinflammation and neuropathology in COVID-19." That's really big news. If they know the mechanism, then they can find counteracting agents. There's a lot more to that study, but I'm still exhausted and can't really follow it at the moment. I'm hoping to learn if it's the S1 or the S2 protein, or both together, that causes the clots. Still, though... this discovery is very good news.
