It’s variant day at the Covid Cafe

Posted on by

Welcome to the Covid Cafe, my friends. We have two variants on the menu today.

 

BA.5

Our first variant, BA.5, has gotten better than previous versions at evading both the vaccines and the immunity people acquired from earlier infections. But where previous omicron variants tended to stay in the upper respiratory tract, making it somewhat milder, BA.5 has picked up some mutations from the delta variant–that’s the most damaging variant to date–and it’s very pleased with them, thanks, and with itself for being so clever. 

They may be the reason it’s better at infecting cells than those respiratory-type omicron variants, and why it may be more serious. 

Seeing it circle back in this way doesn’t make me want to go out and celebrate. On the positive side, though, the current vaccines do still protect against its worst effects. But sensible people are recommending masks, ventilation, and distance–all those things governments and a lot of our fellow citizens have gotten bored with.

BA.2.75

Are we having fun yet? 

Our second variant is BA.2.75. It seems to spread quickly and to evade immunity. How hard it hits people is yet to be determined. It’s also called Centaurus. I have no idea why and my brain isn’t willing to expend any bandwidth on it, but since it’s also possible that the thing has peaked, it has a second name: scariant. 

Come fall, updated vaccines are expected to target the omicron mutations. I’m in line already, and rolling my sleeve up.

 

However

Efforts to create a pan-coronavirus vaccine have slowed down for lack of funding, lack of any sense of pressure, and lack of even marginal good sense. The current vaccines are still keeping death and destruction to a minimum, and hey, that’s good enough. Let’s just stagger on.  I could toss in a quote or two here, but hell, you get the point. Follow the link if you like. It’s find-your-own-quote day here at the cafe.

In addition, testing candidate vaccines won’t be as easy it was at the beginning of the pandemic because Covid isn’t raging through populations the way it was. Pre-existing immunities make their effectiveness harder to measure.

 

Other mutations

A team that’s been analyzing millions of omicron samples in order to study its mutations reports that omicron alone has 130 sublineages. A member of the team, Kamlendra Singh, thinks vaccines might become less effective over time.  

“The ultimate solution,” he said, “will likely be the development of small molecule, antiviral drugs that target parts of the virus that do not mutate. While there is no vaccine for HIV, there are very effective antiviral drugs that help those infected live a healthy life, so hopefully the same can be true with COVID-19.” 

Singh helped develop CoroQuil-Zn, a supplement that infected people can take to help reduce their viral load. It’s currently being used in India, southeast Asia, and Great Britain and is waiting for FDA approval in the United States.

A virologist writing in the Conversation agrees, at least in part, saying that vaccines targeting recent variants will inevitably fall behind as the virus mutates. “Vaccines that generate antibodies against a broad range of SARS-CoV-2 variants and a cocktail of broad-ranging treatments, including monoclonal antibodies and antiviral drugs, will be critical in the fight against COVID-19.”

 

Long Covid news

Long Covid’s too stale for the cafe, but it’s not growing mold yet, so let’s have a nibble out here in the alley. 

The BMJ (formerly known as the British Medical Journal) has summarized 15 studies showing that the vaccinated are less likely than the unvaxxed to end up with long Covid. That’s most true of people over 60 and least true of people between 19 and 35. 

Long covid can range from annoying to life changing (in a bad way, in case that’s not already clear; it won’t make you grow wings or develop superpowers). It also ranges from transient to no-end-in-sight. In the UK, 2% of the population has reported having it and in the US, that’s 7.5%. 

Or by another count, 2 million people in the UK have it. That may or may not work out 2%. Don’t worry about it.  

Why is the percentage in the UK so different from the one in the US and why don’t I care if the UK numbers match? Because no one’s tracking long Covid systematically. It can get pretty weird out there.  

With that out of the way, let’s talk about the important stuff: “hy did the British Medical Journal change its name? I don’t know, but since my father did the same thing, I shouldn’t roll my eyes about it.

Which is unlikely to stop me. Especially since my father didn’t change his name to an abbreviation,but to the last name I use although I have no deep-rooted claim to it.

On the positive side, that bit of history means I know for a fact the Josh Hawley isn’t a relative–even a distant one.

*

In the absence of systematic tracking, a UK study compared a big whackin’ number of people’s medical records to see what they could learn about long Covid. 

Among other things, they were able to add 42 symptoms to the existing list. (Yeah, progress comes in some annoying colors.) The new ones include hair loss, reduced sex drive, erectile problems, swelling limbs, and bowel incontinence.

I did tell you it could be serious, didn’t I? You should listen to me. 

They also organized the symptoms into three categories: 80% of the people with long Covid symptoms had a broad spectrum of problems, from fatigue to pain; 15% had mental health and cognitive problems, from depression to brain fog; and 5% had respiratory problems.

*

A small study treated long Covid patients with cognitive symptoms by using hyperbaric oxygen therapy, and the results were enough to give a person hope. The group that got the real treatment had “significant improvement in their global cognitive function and more cognitive improvement related to their specific damaged brain regions responsible for attention and executive function,” along with improvement in their energy, sleep, and psychiatric symptoms.

The patients who got the placebo treatment didn’t, although they did get a simpler sentence with no fancy language or quotation marks.

The treatment, unfortunately, isn’t something you can set up in your garage. It involves five treatments a week for two months in a machine that looks like a mid-size submarine. 

 

Protective actions you never thought of

Covid is less likely to kill or hospitalize people who fast at least one day a month than it is to do either of those things to those of us who think eating should be a daily practice. This may be because fasting reduces inflammation or it may be attributable to a couple of other reasons that you can look up yourself by following the link.

The bad news? The study involved people who’d been fasting intermittently for decades. It offers no information on people who took it up twenty minutes before becoming infected.

 

A bit more about vaccines

I’ve found enough shreds of good news that I can spare you one more piece: Vaccination, although it doesn’t prevent Covid, does seem to reduce the odds of infection. Not by as much as we’d all like, but I don’t know about you, I’ll take any percentage I can get.

You want details, though, right? Fine: In the second wave of the pandemic, vaccinated National Health Service employees who worked face to face with patients were 10% less likely to get infected than unvaccinated ones. And I’ll remind the assorted anti-vaxxers who pop up here periodically that the primary value of the vaccines lies in preventing death and serious illness, which (do you really need to be reminded?) is not a bad thing. They haven’t turned out to create sterilizing immunity, and that’s a damn shame but doesn’t mean the people who recommend them should be burned at the stake. 

No one’s offered to do exactly that to me yet, but the conversations do have a way of turning hostile. Or starting out that way. A recent comment opened with, “Stop lying, Ellen.”

And I appreciated the suggestion, since hadn’t thought of that myself. I also appreciated the generous and high-minded approach to discussion. Let it be a model for us all.

*

But forget about me. Ben Neuman, a professor in the Department of Biology and chief virologist at the Texas A&M Global Health Research Complex, has another reason to get vaccinated: “to avoid the brain damage that often comes with COVID. During a natural infection, the immune response around your brain will starve cells of oxygen, and the effect is that you will lose a lot of gray matter—something like a stroke. Unlike a stroke, where usually only one part of the brain is affected, COVID seems to affect the entire brain, so you don’t necessarily lose one thing, like the ability to control nerves on one side of the face, you lose a bit from everywhere. COVID-associated brain damage only happens with infection, not with the vaccine, and having a strong set of white blood cells trained by the vaccine is likely to be helpful in preventing brain damage.” 

 

Okay, but what about monkeypox?

Let’s forget about whether monkeypox is a pandemic or an epidemic or just a damned nuisance. Those–especially damned nuisance–have technical definitions that, for a bunch of free-range blog readers, aren’t the most useful standards. The more pressing question is, How much of a problem is this likely to be?

After what sounds like a lot of internal argument, the World Health Organization declared it a global health emergency. The disagreement, as far as I understand it, comes from this: Diseases that spread on the air (think Covid or flu) are bigger worries. They’re easy to catch. Monkeypox is spreading through touch. That doesn’t make it fun and I don’t recommend rubbing up against anyone with a rash right now, but it does mean transmission’s slower and more difficult.

It’s also less deadly than Covid. 

If that’s not reassuring enough, existing vaccines can slow the spread–or they can once production catches up with the need.

On the other hand, it’s popping up in a wide range of countries and seems to have surprised the experts.

Monkeypox could (I’ve read) go in two directions: It could establish itself in many countries as a sexually (an also not-sexually) transmitted disease that people will have to deal with or it could be gotten under control. The first prospect isn’t fun, but it’s still not Covid all over again.

Updates on the fight against Covid: from far-UVC to nasal sprays

Posted on by

Studies showing that far-UVC light kills coronaviruses started circulating fairly early in the pandemic, but they were small studies and the whole project seemed marginal–one of those promising possibilities doomed to be ignored by the folks who know best. A new study might be changing that. 

Might, mind you. As Yogi Berra might or might not have said, “It’s tough to make predictions. Especially about the future.” *

But first, let’s talk about UVC light: It’s short for ultraviolet light, and it kills germs, which (you may remember) we have reason to think is a good idea these days. But UVC has some bad habits. Basically, it doesn’t like people. It can burn the skin and damage the eyes, so if you want to disinfect a room with it, you have to figure out how to keep the light and the people apart. 

That’s awkward, what with Covid’s habit of circulating through the people’s lungs.

Far-UVC, though, doesn’t have those bad habits. It has a shorter wavelength, so it doesn’t penetrate skin or eye cells. But it still slaughters viruses and bacteria, since they’re smaller than the cells humans are interested in protecting.

Irrelevant photo: primroses with violet

So we now have UVC, far-UVC, and a bunch of dead viruses. 

The earlier studies demonstrating far-UVC’s usefulness and safety were conducted in small experimental chambers, and that left open the question of whether it would work in less controlled situations. Now someone’s done a demonstration in real-world conditions–a fairly ordinary room with roughly the same ventilation as a home or office, which is about three air changes per hour.

Does your home change air three times an hour? Does mine? Haven’t a clue, so let’s take their word for it. 

Under those conditions, far-UVC slaughtered 98% of the test microbes within five minutes. Compared to other ways of cleaning air, that’s–to quote someone involved in the project–spectacular. 

I know that, gentle vegetarian that I am, I’m not supposed to be cheering mass slaughter, but nobody ever accused the human race of consistency, and I am, to the best of my knowledge, predominantly human. 

If you want more detail of the experiment, you’ll have to follow the link. It involves numbers, although not many of them. But it doesn’t take many to send me running. Before I left, I did take in that the approach works with viruses, bacteria, and any additional infectious beasties that I’ve forgotten, none of which can mutate to develop a resistance to it.

So in the interest of public health, will far-UVC be coming to all indoor spaces near you? I’d love to think so; it only makes sense. The problem is that it not only makes sense, it costs money. Granted, it would also save money by making indoor air 98% safe, keeping us healthy, and quite possibly getting the pandemic (and assorted other diseases) under control, but we’ve all lived long enough to know that logic doesn’t necessarily apply. It’ll depend on who would be saving the money, who would be spending, and who would be making it it–not to mention who can see half an inch in front of their nose.

In the UK, I predict far-UVC will be adopted only if someone with strong ties to the Conservative Party–preferably a huge fuckin’ donor–goes into the business. At that point, it will become the savior of the nation and we’ll have a world-beating promise to install it everywhere. Some huge amount of money will then be spent and it will be installed in nowhere near as many places as we were promised.

But it’s hard to make predictions. Especially about the future.

*

UV can also be used to clean N95 masks, a new study demonstrates. Early in the pandemic, when protective gear was in short supply, people in medical settings tried pretty much everything to make the gear they had last longer, including disinfecting it with UV, since they had the equipment on hand for other uses. The masks were only meant for a single use, but they were desperate enough to stretch that.

Dianne Poster, a co-author of the study, said, “Right now, UV technologies are really in their infancy with respect to the healthcare environment.” And I’m quoting that because it strikes me as relevant–at least vaguely–to the use of far-UVC as well.

*

And while we’re in UVC mode, researchers have come up with a system that can alternate between plain ol’ white LED light to, you know, see by and UVC light to decontaminate an indoor space. The drawback is that it depends on motion-sensors to let it know when the room’s empty. So you wouldn’t want to fall asleep at your desk or be in the sensors’ blind spot.

The lights work in standard lighting fixtures, which should keep the cost down.

 

Other new developments

A nasal spray that promises to prevent Covid infection for 12 hours or treat the early stages of infection has passed mouse studies with flying colors and a company is trying to raise money for human studies, development, marketing, and all the uproar necessary (or at least expected) to get a product to market. 

Is this the same anti-Covid nasal spray I wrote about a few weeks ago? Possibly. At the moment, this one’s called N-0385, so you can see why the name didn’t stay in my mind. But who cares? I want this stuff badly enough to risk writing about it twice.

*

For the first time, doctors have used a vaccine to clear Covid from the body of an immune-suppressed patient who tested positive for seven months after first catching the virus.

This wasn’t long Covid, where symptoms keep dancing long after the viral band has packed up its instruments and gone home.The patient tested positive through that whole time. 

*

Assorted other tests and treatments and vaccines are also in the works. The new tests are faster and more accurate than what we’re currently using. Some of the treatments hold the promise of working against mutated forms of Covid by targeting a part of the virus that can’t mutate–the virus dies if it plays around with that spot. One vaccine would be highly tweakable when not just new variants but new diseases emerge, and I think we’ve learned by now that new diseases will emerge, although whether we’ll act on that knowledge is a whole ‘nother question.

I mention all this to say, Hang in there, folks. We will get through this.

 

Omicron BA.2

How dangerous is the new omicron variant, omicron point two? (It’s actually called BA.2, but never mind that.) For starters–and forgive me if you already know this–it’s no tougher than omicron point one. It can’t lift heavier weights, can’t run faster, and to date hasn’t stolen lunch money from any more kids than point one has. 

It is more contagious, but according to one measurement not by that much. You can tell that by how long it’s taking to become the dominant strain.

So if this study’s right, it kind of fooled us there. Early reports were that it was much more contagious.

The bad news–isn’t there always bad news?–-is that the people studying it expect people to get reinfected. You already knew that too, right? It’s a coronavirus. People do tend to get reinfected by them. So you have my encouragement to deck the next person who mentions herd immunity to you. Or you can ask me to do it if you’re not in the mood. I’m five foot not very much, 75 years old, and terrifying in a fight. 

And I need the exercise.

The article I stole all this from reminds us that “we’re entering a different phase of the pandemic,” and “need to now assess whether [a new variant is] a risk to the general population, . . . a risk to an individual person” or a risk to a specific group such as the elderly or the immune compromised.

Which is an interesting way of seeing the problem and I can’t help wondering if it’s an invitation to write off a few inconvenient groups in the presumed interest of the general population and to stop looking at Covid as a public health issue and start looking at it as a personal problem. 

But maybe that’s just me being cynical. 

The article ends with a call for people to wear masks when they’re sick, even if what they have isn’t Covid, because they’ll protect other people from whatever they have. It’s a radical thought: inconvenience yourself marginally to help other people significantly. 

There’s got to be something wrong with that.

*

In the meantime, the World Health Organization says omicron point 2 is 30% more transmissible than omicron point one. I can’t compare that estimate to the one above since their measuring tapes are marked differently. Make what you can of it.

WHO also says the European countries that have dismantled their anti-~Covid measures have done it too “brutally,” going from too many restrictions to too few. It reminds us that cases are rising.

In Britain, they’re rising significantly, and deaths are also going up. Not the way they did at the start of the pandemic, but the trend is up all the same, and the people who are dying of it are still dead. We don’t seem to be treating Covid as a public health problem anymore, just a personal one. If we see a coronavirus coming at us, we’re advised to either duck or dodge to the left. 

It’s a fantastically effective strategy.

 

* Yogi Berra is also supposed to have said, “I never said half the things I said.” So you want to approach his quotes with caution. They’re likely to explode on contact with a human brain.

What do we know about the new Omicron variant?

Posted on by
27

Well, on its wanted poster, it’s called BA.2, so let’s call it that. We don’t know what it calls itself. It’s estimated to be 1½ times as infectious as its relative BA.1.

What kind of relatives are they? They’re being called sister viruses, since .2 isn’t a descendant of .1, although why it’s a sister instead of a brother I don’t know. Viruses never allow themselves to be shoved into little pink or blue baby suits.

Never mind. If they want to be sisters, they can be sisters. Kids, you can be anything you want to be. 

Within limits. We’ll discuss the fine print when you’re older.

Let’s set that aside, okay? We’ve got some good news for a change: BA.2 doesn’t seem to be any more dangerous as BA.1, and the vaccines seem to be as effective against .2 as they are against BA.1.

Irrelevant photo: The first celandine are out. They’re looking a little bruised, as if they’ve gone nine rounds with King Winter, which they have, but they’re in bloom.

End of good news. Dr. Gregory Poland, of the Mayo Clinic’s Vaccine Research Group, said that variants will “continue to happen and infect every unvaccinated person until people are vaccinated and until they’re wearing a mask. You can choose to ignore these facts―these clear data―but the virus could care less what we think. The virus is going to find people who do not have protective immunity and infect them.”

That should be “couldn’t care less,” but you know what he means.

 

So what should we be doing?

According to WHO Director-General Tedros Adhanom Ghebreyeus, “We are concerned that a narrative has taken hold in some countries that because of vaccines—and because of omicron’s high transmissibility and lower severity—preventing transmission is no longer possible and no longer necessary. Nothing could be further from the truth. It’s premature for any country either to surrender or to declare victory. This virus is dangerous and it continues to evolve before our very eyes.”

That quote’s a few weeks old, but we’re not listening. Many countries are undoing their Covid restrictions because, hey, they know better. And it’s over. 

Meanwhile, Covid’s overwhelming Hong Kong and desperate hospitals were setting up beds outside.

How much of Hong Kong’s population’s vaccinated? The closest I could come to an answer is this: If you compare the number of doses delivered to the population, 78.9% of the people could have had two doses. 

 

Vaccine news

Scientists at the Wistar Institute are working on a vaccine that, at least in animal studies, creates a stronger, broader, and more durable protection than the current vaccines, and does it with a single, low dose that can be stored at room temperature. If that’s not enough, it can also be adjusted quickly as new variants arise.

And it makes a decent cup of tea if you ask politely.

It uses three technologies: immune focusing, self-assembling nanoparticles, and DNA delivery. Now let’s see if I can explain what those are.

Well, no, I can’t quite, but I can throw some language at you to make it sound like I understand a bit of this. 

The vaccine shoots you some naturally self-assembling proteins (whatever they may be), and they then form nanoparticles that arrange themselves–oh, hell, I’m lost, so I’ll quote: “By arranging themselves into structures that resemble an actual virus, the nanoparticles are more easily recognized by the immune system and transported to the germinal centers, where they activate B cells which produce protective antibodies.”

To translate that, they use long words to activate your immune system, creating “stronger levels of protective, neutralizing antibodies.” 

If I understand this correctly, all this convinces the body to produce things that would normally be produced in high-tech factories.

They’re at the animal-test stage, and so far it’s producing a stronger, longer-lasting immune response than the existing vaccines. With that data in their pockets, they’re scrambling around, trying to raise the money for human trials. 

*

Another set of trials is using a nasal spray to deliver a booster vaccine, focusing the immune system on the areas Covid attacks first, the nose and lungs. It depends on the recipient having already had an mRNA vaccine or possibly a previous infection.

The idea, since this focuses the protection on the nose and lungs, that it would prevent both infection and transmission. 

They’ve run tests on mice and will test the approach on larger animals, then hope to start human trials.

*

Researchers at the Massachusetts Institute of Technology have worked out a way to inject RNA and DNA into the stomach lining by way of a capsule the size of a blueberry, allowing it to reach the digestive tract directly. 

Other than driving anti-vaxxers nuts, what’s the purpose? It would let you–or, ideally, someone who knows what they’re doing if you’re no more skilled at this than I am–deliver medicine for gastrointestinal problems directly to the gastrointestinal work site. It might (or might not–it hasn’t been fully tested yet) also let you deliver an RNA vaccine in a new and interesting way, one that would be easy on needlephobes and wouldn’t make small children scream, although that last possibility depends on someone getting them to swallow the blueberry. 

And, of course, it would drive the anti-vaxxers nuts. 

 

Do masks work?

A California study reports that wearing an N95 mask or its equivalent reduces the chances of becoming infected with Covid. In Europe, the N95 is called an FFP2; both are also called KN95 masks or just plain ol’ respirators.

These aren’t the blue disposable masks that blow around the parking lots of this and many other fair lands. They’re also not your average cloth masks. They’re the more expensive ones made of I have no idea what but designed not just to keep you-the-wearer from sharing your germs but also to protect you-the-wearer from stealing other people’s.

That’s other people’s germs, not their masks, and that’s a huge and important difference. As mask mandates are reduced and as some people insist on their right to breathe in other people’s faces, they become a form of self-defense. 

Some N95s are disposable. Others are reusable–up to a point, estimated at about 40 hours of use. 

The study involved 3,000 Californians, and it’s a less than perfect study. For one thing, it relies on what people say they’ve done, with no reality check built in. That’s always dicey. You know what humans are like. It was also limited to people who chose to get tested for Covid. Still, it might give us a hint or two about what’s happening out there.

So with all that out of the way, would I please tell you what the damn thing said?

Why yes, I’d be glad to: 

People who said they always wore masks (any kind of masks) in public indoor settings were 56% less likely to test positive for Covid than people who didn’t wear masks. That went up to 83% for people who wore N95 masks. People who wore surgical masks were 66 percent less likely to test positive.

A more controlled study, published in the Proceedings of the National Academy of Sciences, tested the rate of transmission when an infected person talked for an hour to an uninfected person. When the person who wasn’t infected wore a well-fitting mask N95 or its European equivalent, the FFP2 mask, the risk of infection was 20 percent. 

If both people wore surgical masks, the risk of infection went up to just under 30 percent. When both N95 masks or their equivalent, though, it dropped to 0.4 percent. 

The two studies reported their findings differently, so we can’t compare the results–or I can’t anyway–but the second one does tell us that two people wearing good masks present less of a risk than one person doing the same. 

Should we do the howevers now?

To work most effectively, the N95 mask has to be fit tested, which is something they do at hospitals and in hazardous workplaces. It’s complicated enough that no one does it at home. Or in the supermarket, or on the bus. Most people who put them on without fit testing them don’t get a complete seal between the mask and their face, even if it feels like a good fit. 

So they’re less than perfect protection, but even if they’re not fit tested they’re still decent.

How decent? Sorry, I sank, but you’re welcome to dig around in here and figure it out yourself. I warn you, it involves numbers. Also words. Don’t say you weren’t warned. In layperson’s terms, I think the answer would be not enough to make someone with a compromised immune system safe but more decent than a cloth or disposable mask. 

I haven’t looked into how the second study was set up, but I did wonder. Did they actually use an infected person, putting the uninfected person at risk? Dunno. How many of the people being talked at expired from sheer desperation before the hour was up? Dunno that either. I’m sure it depended on the talker. With some people I’ve known, I wilt after fifteen minutes of listening.

Is the pandemic over?

Posted on by

Can I be the bearer of bad news? 

You’re not here to answer and the news won’t surprise you anyway, so I’ll just go ahead: The World Health Organization tells us that the pandemic’s not over. 

How do I know? Because Tedros Adhanom Ghebreyesus, WHO’s director general said, “This pandemic is nowhere near over.”

That’s a subtle way of putting it, but if you pay close attention you can tease out the message.

He also said, “Omicron may be less severe, on average, but the narrative that it is a mild disease is misleading. Make no mistake: Omicron is causing hospitalisations and deaths, and even the less severe cases are inundating health facilities.”

And if that’s not enough, “While Omicron causes less severe disease than Delta, it remains a dangerous virus—particularly for those who are unvaccinated. We mustn’t allow this virus a free ride or wave the white flag, especially when so many people around the world remain unvaccinated.”

The “overwhelming majority” of people admitted to hospitals are unvaccinated, he said.

 

Irrelevant photo: The first daffodils are out.

Has Covid gone endemic?

But what about the idea that Covid’s changing from a pandemic to an endemic disease and that we need to stop whining and learn to live with it? 

Let’s start by figuring out what that means: An endemic disease is “consistently present but limited to a particular region. This makes the disease spread and rates predictable.” 

Sorry, but I need to step in here. That last sentence doesn’t mean that being consistently present and limited to one region makes the disease spread. It means those things make the disease’s spread predictable.

Which was probably already clear, but I couldn’t help myself. I used to misunderstand people for a living, and old habits are hard to break.

So how do we measure up to that definition? We’ve blown it on the “limited to a particular region” part, but let’s not be fussy. Are the spread and rate predictable? 

Nope. Not only do we have sharp spikes, we have no idea when a new variant will come along or how dangerous or benign it’ll be. We do know that the climate’s right for creating new variants.

Another defines an endemic disease as constantly present but not causing the upheaval or massive number of infections that an epidemic does. Covid hasn’t become endemic by that definition either.

But again, let’s not be fussy. Even if Covid doesn’t fit either definition, couldn’t we pretend it does, get over our fear, and learn to live with it?

Well, it depends on how we want to live. Or die. Being endemic doesn’t mean it’s no threat. Before penicillin, tuberculosis was endemic. [Late correction: Penicillin has nothing to do with tuberculosis. See the comments below. It’s the things you think you know that trip you up.] So was syphilis. They wrecked a lot of lives. They killed a lot of people. People learned to live with them because they had no choice, but I wouldn’t make a virtue of it. 

It would be interesting to look at how much resistance measures to control their spread met. But that’s another post.

Learning to live with Covid is one of those phrases that, when you look at it, means nothing. Does it mean we tear off our masks, join a germ exchange, and relearn the lyrics to that Country Joe and the Fish song with the line “Whoopee, we’re all going to die”? Or does it mean we wear masks religiously, invest in some serious ventilation, and pass vaccine mandates? They’re both ways of living with a virus.

Does it mean learning to live with a constant threat, not just of death but of disability from long Covid–a threat that no one’s been able to quantify yet? If so, how will we decide to live with it?

Michael Ryan, the head of emergencies at WHO, said, “Endemic malaria kills hundreds of thousands of people; endemic HIV; endemic violence in our inner cities. Endemic in itself does not mean good. Endemic just means it’s here forever.”

Okay, he skipped the predictable part, but we did say we weren’t going to be fussy.

“What we need to do is get to low levels of disease incidence with maximum vaccination of our populations, so nobody has to die,” Ryan said. “The issue is: It’s the death. It’s the hospitalizations. It’s the disruption of our social, economic, political systems that’s caused the tragedy—not the virus.”

And in case you’re betting on the next variant being milder than Omicron, mutation isn’t a one-way street. The direction of travel is random. 

 

Could you scrape up some good news, please?

Possibly, but let’s whisper so we don’t spook it: Some experts say that once the Omicron wave recedes we may get a period of quiet. The theory is that we’ve built up widespread immunity that could keep future waves from hitting as hard as they have in the past. 

Do waves hit? Is that a mixed metaphor? Do we care?

Probably, but let’s focus on the important stuff.

That’s not a unanimous opinion and other experts are more cautious, reminding us that it’s not clear how long Omicron immunity will last or whether a new variant will evade it. Omicron has demonstrated that even a relatively mild version of Covid can put a huge strain on health systems–and on the people who work in them. 

And as Boghuma Titanji, a virologist at Emory University School of Medicine, put it, “Wealthy countries moving on, I fear, will push the issues of access to vaccines and therapeutics access down the global priority list.” Which would mean not only more deaths in poor countries but (self-interest alert here) more variants loose in the world.

On the other hand, data suggests that the human immune response becomes better and broader every time it’s exposed to Covid’s spike protein. 

On the third hand, however, Leif Erik Sander, an immunologist at the Charité University Hospital, says that Omicron’s spike is so different from the spike in earlier variants that it’s not clear just how much immunity the Omicron wave will leave us with.

At which point we’re out of hands and it’s time to talk about what the next variant might look like. One possibility is that Delta could stage a comeback tour. Omicron was able to spread so quickly in part because the earlier versions hadn’t left us immune to it. Once that advantage fades, it may die back, leaving Delta room to work. Or they could work out their disagreements, move in together, and have babies, which could easily be uglier than either parent.

And, since a handful of antibodies does not an immune system make, what happens if a new variant evades not just our antibodies but our T cell response? (Reminder: T cells are an essential part of your immune system. Don’t leave home without them.) Well, if that happens “we’re dealing with another pandemic,” Shabir Madhi, a vaccinologist at the University of the Witwatersrand, said. But “the likelihood of that happening, I believe, is quite slim.”

 

Let’s try that good news thing again . . .

. . . because my last try didn’t go well.

Researchers in Finland are working on something they call a biological mask–a spray that could (assuming the tests go well) protect a person against Covid for 8 hours. 

It’s not meant to replace vaccines but to supplement them. If a person’s immune system doesn’t respond well to the vaccines, this spray is their friend. Or if they’re faced with a combination of a vaccine-evading variant and too many human beings in a risky setting, then ditto. 

The active molecule in the spray is called TriSb92, a name I forgot as soon as I got past the comma. Never mind. It’s a clever little beast that targets a part of Covid’s spike protein that’s common to all variants–at least so far–and once it makes contact it keeps the virus from going to work. You know what that’s like. It calls in sick and loses its job because spike proteins have no union and therefore no sick leave and no job security. 

If it was anything other than the Covid virus I’d feel bad about that, but it’s got it in for us. Have no mercy.

The developers think the spray might also be effective against new coronaviruses that emerge. Keep your fingers crossed. This sounds promising.

What we know about the Omicron variant

Posted on by

With so many things about the Omicron variant still uncertain, I’m happy to find a bit of (apparently) solid news about it: five key symptoms. 

They’re not the same as the earlier variants’ symptoms. They’re extreme tiredness, night sweats, a scratchy (as opposed to sore) throat, a dry cough, and mild muscle aches. Officially, though, UK government websites are sticking to the old three: a high fever, a new continuous cough, and changes to your sense of taste or smell. 

So is Omicron milder? Possibly. Hopefully. The World Health Organization–a.k.a. WHO–thinks it is. Probably.

But what the hell, we don’t know yet, and Moderna’s chief medical officer, Dr Paul Burton, said it “poses a real threat.” He’s not convinced that it’s milder. With Covid, severe disease waddles in a couple of weeks behind infection, and South African reports that it’s mild may have to do with specific conditions there.

Burton says Omicron and Delta are likely to circulate together for some time. So if you’re reaching for your seatbelt buckle, thinking you could unsnap the beast because you won’t be needing it, you might want to wait a while. Nothing’s certain yet.

Could somebody give us a bit of good news, please?

Well, yes, although it’s not ready for use yet. Scientists at Aarhus University (that’s in Denmark, and I had to look it up too) have discovered a molecule that covers the nasty little spikes on the Covid virus, which then keeps it from entering human cells, spreading infection, and throwing those loud and drunken parties that have made the last couple of years so difficult for us all.

It’s not a vaccine but it uses some of the same building blocks that the mRNA vaccines do. No, don’t ask me. Just nod and look wise and someone will think you know what that means. 

One of the implications of this is that it’ll be cheaper and easier to make than the antibody treatments that are now used to fight the most serious Covid cases. 

It can also be used to detect the virus. And make coffee.

No idea. Just nod and look wise.

It’s done well on detecting the Delta variant, but it’s too early to have data on how it does with the Omicron.

It sounds like a new antiviral drug is in the pipeline, although it also sounds like it’s in the early stages. The article I got this from–let’s say the language could stand to be more considerate to your average blogging idiot. I think we’re talking about a pill–the article says it’s “orally available,” but then, so’s my tongue–and (unlike my tongue) it would only need to be taken once a day. 

Other information? It works against Covid and other respiratory RNA viruses–at least in animal models. It’s not coming off the assembly line yet, but it’s something to keep our eye on.

If it comes through, it will join the Pfizer and Merck antivirals that are a few steps ahead, approved in some places, and seeking approval in others. They can be used to treat mild to moderate Covid and keep it from progressing–or, basically, from killing you. Or landing you in the hospital. 

 

Spotting Omicron

Different countries use different tests for Covid, and one of them happens to be good at spotting the Omicron variant. Among other things, that means that information about the variant will be coming in at different rates from different countries.

 

Going beyond neutralizing antibodies

Early studies of the new variant have reported on how well prepared our neutralizing antibodies are to win a debate with it, and neutralizing antibodies are the focus because they’re easy to measure, but they’re not the only tool our immune systems have on hand. When it loses a debate, it can always fall back on a different, time-tested tactic: throwing chairs.

Okay, very small, metaphorical chairs. 

The body’s second line of defense is made up of binding antibodies, T cells, and memory B cells. They’ve got short tempers and long memories, and when they’re not actively fighting Covid they lift weights and make threatening noises. 

When they’re working, though, they target a different part of the virus than the neutralizing antibodies do–and in the Omicron variant it’s not as heavily mutated a part. 

So if you’ve had a booster shot, you’re not totally unprepared to fight this thing. This is, admittedly, early news, and more studies are needed before we’ll know how well they aim those chairs. 

 

Spreading Covid in the House of Commons

As Britain’s Conservative Party shakes itself apart over how to respond to the new variant, we’re being treated to scenes that make the House of Commons look like a Rubens painting. 

In case you’re lucky enough to have missed Rubens, he liked to paint his people in piles, sometimes adding an unexplained cow to the mob. (Apologies: The link won’t take you to the painting with the cow. I swear I saw it one–it’s not something my imagination’s capable of coming up with–but I reached my limit before I found it.)

Why is that a good parallel to the House of Commons? Earlier in the pandemic, MPs were allowed to basically phone in, working from home and voting safely from a distance. I don’t know if they were able to debate from home, but then no one listens to anyone else anyway, so what did it matter?

Cynical? Not me.

That ended, in spite of protests, and MPs now have to gather in absurdly small rooms to vote. As an MP from the Scottish National Party put it, “The only way to pass regulations to try and get Omicron Covid back under control will be for about 400 people to pack into a room big enough for 100 to record their votes.

“They’ll do this up to four times in succession. In between, they won’t be able to go too far so will pack out the lobbies at either end of the chamber waiting for the next vote to be called.

“Several MPs have tested positive for Covid in the last few days so there’s a very high probability that others are carrying the virus but have not yet shown symptoms or given a positive test. What could possibly go wrong?”
