Case Update: July 6th, 2022; BA.5 may be more dangerous than previous versions, and escapes immunity from Omicron infections

This is a case update. I’ll also discuss important new data in regards to BA.4 and BA.5 variants which you may want to take into account as you move around in our “post-COVID” world. You should especially read this if you’re one of the few who have never had COVID. I’ll also suggest a range of strategies that you may employ to keep yourself safe.

The update is actually not much different in the US from last week. Cases are medium-high but flat right now, and we have happily not yet seen increased deaths due to Omicron BA.2.12.1, BA.4, and BA.5 variants.

BA.4 and BA.5 now predominate in the US, being 17% and 54% of cases respectively. Together, they are 70% of new cases. Hospitalizations are up slightly, but not nearly so high as in January, at the height of the Omicron wave.

Keep in mind that many and perhaps most people who have COVID right now are not getting tested by a health care provider, and are not being treated, so they are not a “case” and do not appear in current statistics. While it’s great news that we haven’t yet seen increased deaths in the US, there is sobering news which may cause a change in this in the next few weeks.

BA.5 reinfecting Omicron patients: A few weeks ago, an urgent care doctor friend of mine said that he had seen some patients who have had Omicron twice. Just this week, some friends of mine who had Omicron in January, just like me, came down with it again. They have COVID right now. Like me, they were pretty miserable in January for a full 2 weeks. Happily, their symptoms are moderate now, like a bad cold, just for 2 or 3 days.

Just yesterday, John Campbell released a video regarding BA.4 and BA.5. While he has a pretty bland delivery and focuses on the UK, he’s honest, balanced, and one of the only pundits still covering COVID in any detail.

Dr. Campbell’s newest video has some sobering information about BA.4 and BA.5 variants. As you can see from the data above, BA.5 is more infectious than BA.2 and BA.4, and will probably become dominant in the US in the next few weeks.

While still being called an Omicron variant, I wouldn’t be surprised if BA.5 gets it’s own Greek letter. Maybe Pi or Rho.

Unfortunately, Dr. Campbell claims that BA.5 is different enough from earlier Omicrons that they do not provide robust protection against BA.5 infection. He says Omicron is “poorly immunogenic”, but later clarifies in the video that this is likely because SARS-2 variants are changing very rapidly right now. The current COVID vaccines are having little impact, and the virus is changing so rapidly that updated vaccines are not practical to produce, meaning that the age of COVID vaccines is really already over.

For some good news, reinfections are usually milder than previous cases. So if you’ve already had COVID, BA.5 is likely nothing to be worried about.

Portugal had a lot of BA.4 and BA.5 in May and June, and they experienced more hospitalizations and deaths. Some worry that BA.5 may produce more severe cases in “naive” people, those with neither natural nor vaccine mediated immunity. Drs. Kei Sato and Stephen Griffin claim that BA.5 is growing deep in the lungs, like pre-Omicron versions, which makes it more likely to produce pneumonia. Most Omicron variants grow primarily in the trachea, which is why they are less likely to produce severe disease.

Last, Dr. Campbell argues from a letter by Hachmann et al, that prior infection plus vaccination offers better protection than either alone, but that BA.5 is still escaping neutralization. In my personal view, vaccination carries risks of it’s own, so if you are still not vaccinated, I would suggest taking increased precautions rather than vaccination at this point.

Cases in the UK are rising quickly right now, and often is a few weeks ahead of the US in any recent COVID trend. If data from Portugal and the UK hold true in the US, we may expect increasing cases in the US and perhaps more deaths as well.

Viruses have a tendency to become more infectious and less pathogenic over time. While this has been shown to be true many times in the last century, this is only a tendency and does not always hold true. While BA.5 is more infectious than previous versions, it’s tendency to grow in the lungs may make it more dangerous, so BA.5 is bucking the trend.

Strategies: Of course, it can be very hard to predict what will happen next. We also have a lot of different COVID experiences in the US in terms of whether someone has had COVID, what variant they had, whether they were vaccinated, etc. So any suggestions I make may not pertain to you.

Since I had COVID in January, I’ve been behaving in public as if I’m totally protected against a new infection. This may have been warranted, since I haven’t been infected again. I’ve even visited people with COVID at their house, treating it as an opportunity for a free booster. But this new information gives me pause. I may be more vulnerable to BA.5 than I had hoped.

On the other hand, even BA.5 is mild in those with previous infections, so I will likely be OK if I get BA.5. I am still not vaccinated and don’t intend to be. So going forward, I am going to continue to behave as normal, without masking in public at this point.

My main reason for being so careful before I got infected was the Antibody Dependent Enhancement (ADE) issue. Now that I’ve been infected, it’s not useful for me to continue with my previous caution. In fact, the “free booster” method may now help me with future versions more than avoiding infection would.

If you have never had COVID, you may choose to take increased precautions to prevent infection. Wear an N95, KN95, or KF94 mask when indoors in public. Don’t wear a cloth or blue surgical mask. These masks will not protect you from BA.5. Vaccination alone is not likely to be of much protection from BA.5.

If you do end up being infected with BA.5, regardless of the severity of your symptoms, stay home until you’re COVID negative to protect those around you who may be vulnerable.

Will COVID be endemic? A client of mine was kind enough to recommend my posts to his board, saying that my COVID predictions always come true! I would love this to be that case, but I can’t claim that kind of record. I have certainly been wrong during the pandemic. In particular, I’ve said that Omicron will end the pandemic, and that it will won’t likely have a new dangerous variant. BA.5 may end up proving me wrong on both counts. The lightning speed that new variants are developing also challenges my previous statements. I can’t claim to always be right, but I will tell you as soon as possible if I’ve been wrong.

So will COVID last forever? In spite of BA.5, I still say no. While it has exceptions, the tendency for new viruses to be less pathogenic still holds true. I still expect new variants to generally be less dangerous than older ones. In fact, BA.5 will likely still have less impact than previous versions simply because so may people have previous infections.

Fauci’s time with COVID and Paxlovid

This is a post about Tony Fauci’s time with COVID and the drug Paxlovid, which I have discussed in the past.

On June 15th, a story came out about Tony Fauci having contracted COVID, despite having been fully vaccinated and boosted. I didn’t cover this before since I’d already discussed the fact that the vaccines don’t prevent infection by Omicron variants.

However, something else very interesting happened. Dr. Fauci took Paxlovid, which I’ve discussed briefly before, and became COVID negative. But after his 5 day course, he became positive again with worse symptoms. This means that a standard 5 day course of Paxlovid will not necessarily reduce your viral load to zero, and patients may experience “Paxlovid rebound”. Fauci even claims that this kind of rebound with Paxlovid is starting to be seen as “typical” as more patients use it.

The CDC actually issued a warning about Paxlovid Rebound in May, but it was not widely reported.

With so many rebound cases, it’s likely that 5 days is not adequate to eliminate all viruses from the system, allowing rebound. However, Paxlovid does have side-effects, so don’t take it for more than 5 days without consulting your doctor! Hospitals are now only prescribing Paxlovid to high risk patients.

Whenever taking anti-viral or anti-bacterial medications, always take the full course of treatment. If any virus or bacteria survive treatment, they may give rise to a more resistant strain. Don’t just stop your treatment when you feel better. I take anti-biotics as a last report, but when I do, I take the full course. I even made a doctor give me the full 10 day course when she just wanted to give me a half course!

Just to repeat the point on the vaccines, I still hear ads on the radio encouraging vaccination. At this point, the vaccines are really not doing anything against the current COVID variants. There is really no benefit to getting a vaccine or a booster. If you haven’t had COVID yet, I would simply recommend preventative measures. Wear an N95, KN95, or KF94 mask when indoors in public. Cloth and surgical masks will not prevent infection.

Don’t fear, but be smart!

Case Update, June 28th, 2022

This is a brief COVID update. Cases have been flat in the US, California, and San Diego County, neither rising or falling. This may be partially because of the introduction of 2 new variants, BA.4 and BA.5. These new variants are both of the Omicron vintage. The good news is that deaths have not risen for many weeks even after cases rose due to the BA.2 variants.

My guess is that BA.4 and BA.5 will continue to drive new cases for a few more weeks before we start seeing cases come down. It appears that the fatality rate for these new variants is also very low when compared to other COVID variants.

The contribution BA.4 and BA.5 variants in the US is growing, as they new represent approximately 50% of the total SARS-2 viruses in the country.

COVID Update, June 14, 2022; BA.4 and BA.5 Emerge in the US.

This is a COVID update, and I’ll discuss the emergence of BA.4 and BA.5 in the US.

New daily cases have peaked in the US, California, and San Diego. We have yet to see a sustained increase in deaths due to the new BA.2 variant in any of these regions. While new cases have not really started to decrease, the numbers have definitely peaked.

BA.4 and BA.5 in the US: I commented on May 24th about the new BA.4 and BA.5 variants. At that time, the CDC was not reporting these variants in the US. The new CDC bar graph of variants now shows that approximately 20% of the SARS-2 virus in the US now from BA.4 and BA.5.

From the CDC page on Variant Proportions. Note that when I posted on June 3rd, the CDC did not report BA.4 and BA.5 in the US.

Will we have another peak? Maybe. These variants may have arisen in South Africa, and the BA.4 and BA.5 peak has already come and gone there. The peak was much smaller than the original Omicron peak, and generated even fewer deaths. South Africa did not experience a BA.2 wave of Omicron cases.

From Worldometer. The wave starting in December 2021 is the B.1 Omicron wave, the wave starting in April 2022 is the BA.4/BA.5 wave.
From Worldometer. The wave starting in December 2021 is the B.1 Omicron wave, the wave starting in April 2022 is the BA.4/BA.5 wave.

These new variants appear to follow the tendency for new viruses to be more infectious and less pathogenic (disease causing) than earlier ones. So we may see a shoulder to our current peak, but we won’t likely see significantly more deaths. Obviously, I’m using “significantly” in a cold, statistical sense here.

A negative trait of the BA.4 and BA.5 are that they are even less responsive to vaccination than previous Omicron variants. So vaccination is not likely to help much against infection. Reinfection after previous infections with Delta and earlier versions appears to be more likely.

I haven’t seen much in our popular media about these new variants. The only commentator who has discussed these new variants significantly is John Campbell.

If SARS-2 continues to become more infectious and less pathogenic, it may become part of the background, like a cold. I still don’t think it will last forever. I think it will eventually burn itself out.

A note on BA.2: The BA.2 variant is significantly different from the BA.1 variants. Some scientists are now saying that the BA.2 variants should not have been considered an Omicron variant, and should have gotten their own Greek letter designation. The next letter is Pi. Maybe they would have skipped this one to avoid confusion at Marie Calendars!

“No, I would not like some Pi.”

COVID Update: June 3rd, 2022

This is a COVID update. I’ve been posting only every 2 weeks for a while, but this has been an interesting week, so I’m posting a little early.

New case numbers for the US, California, and San Diego County show that the second Omicron wave, I’ll call it the BA.2 wave, has peaked, and numbers are now dropping sharply.

For some reason, my numbers are a little erratic for the last week for the US. This is likely because of irregular reporting by places that Johns Hopkins gets information from, so I’ll also show the US data from Worldometer.

Graph is by me, from data collected from Johns Hopkins University COVID site. Graph is presented in a logarithmic format to emphasize small numbers. Note that each number on the left is 10x higher than the one below it.

Anyway, new case numbers for all three regions are coming down now, and deaths have still not started to come up, despite us being 6 weeks into the BA.2 peak. John Campbell has also pointed out that new deaths have not tracked with new cases, so the BA.2 Omicrons seems to be less pathogenic than previous versions.

And yes, since cases are less severe and over-the-counter testing is available, infections are likely much higher than official reporting suggests.

Still not quite over: Since I had Omicron in January, and current strains are still in the Omicron family, I am not concerned about getting COVID again right now. So the Pandemic is essentially over for me, but people are still getting COVID.

I was with a buddy this week who was very fatigued and miserable, just like I was, but he didn’t have any life threatening symptoms, just like me. So just a word of encouragement for those who have COVID now or will get it in the coming weeks. You can be really miserable and not be dying! You generally only need to go to the hospital if your blood oxygen is low. Different sources have a different definition of “low”, some say below 90 and some say below 95. Feel free to chime in on this if you’re a health care worker! Get yourself a high quality pulse oximeter so you can reassure yourself if your oxygen is normal! Some medical networks also have a messaging system where you can ask your doctor COVID questions without going in.

Also, if you haven’t had COVID recently, supplement with Vitamin C, Vitamin D, and Zinc. A physician friend of mine says he has had patients who’ve had both Delta and Omicron, so “recently” means since December.

Don’t fear, but be smart!
Erik

Post Script:
Mark Foreman sent me a paper he found describing 47 cases in Denmark in which people who had been infected with Omicron BA.1 were also infected with BA.2 just a few months later. The cases were all in young, unvaccinated people who had had mild symptoms from their BA.1 infections.

Since BA.1 and BA.2 are so similar, I find this a little baffling, but my being baffled doesn’t discount the data. The data must speak for itself. One possibility suggested by the mild symptoms is that the patients had a low dose exposure to BA.1, so had mild symptoms, and perhaps only mounted a medium immune response to BA.1, allowing infection by BA.2. This is just a guess of course.

In all cases, the BA.2 infections in this group produced mild symptoms.

A very interesting paper that will perhaps give more insight into how our immune systems interact with this disease!

Case Update, May 24th, 2022; Omicron variants BA.4 and BA.5, Monkeypox, and Hepatitis in Children of Unknown Cause

This is a case update.  I’ll also talk briefly about new Omicron variants, BA.4 and BA.5, and also the new Monkeypox virus, and several cases of hepatitis in children.

New confirmed cases are still increasing due to the new Omicron BA.2 and BA.2.12.1 variants, which are now nearly 100% of cases in the US.  Hospitalizations are also up in the US.  However, new daily deaths are still not rising in the US or California, with only a temporary blip in San Diego County.  I have often cautioned that deaths trail cases by 2-5 weeks, but for the first Omicron wave in December and January, deaths trailed cases by just 1 week. Since we still aren’t seeing an increase in deaths after 6 weeks, this suggests that the BA.2 variants are not as deadly as even the BA.1 Omicron variants.

I’ll also point out that I continue to have friends who are getting COVID right now, meaning they are getting one of the BA.2 variants.  While some feel bad, none are going to the hospital, and none are becoming a “confirmed case” by getting tested in a medical setting.  If this is true on large scale, then we have lots of infections, maybe even most of them, that are not showing up in the “confirmed case” data.

BA.4 and BA.5:  I’ve heard some news about some more new Omicron variants BA.4 and BA.5.  So far, these variants have not come to the US and have not had a large impact on the pandemic.

Monkeypox virus:  There have been several clusters of Monkeypox cases in Europe, and just a few cases in Canada and the US, about 120 cases in total.  Monkeypox is a pox virus similar to Smallpox.  It is much less much deadly than Smallpox, but can cause death.  It is endemic (widespread and likely permanent) in Africa but does not usually cause serious outbreaks in non-African countries.  It is only moderately infectious, spread by contact and also by respiratory droplets.  It is not spread in aerosol form. Asymptomatic people do not generally transmit the disease.

Those vaccinated against smallpox will still have some immunity against monkeypox.  Pox viruses do not mutate quickly.

All this to say, most infectious disease experts do NOT think that Monkeypox poses a serious health risk to most people, and that it does NOT pose a potential pandemic risk.  Why am I covering this then? Because it’s in the news, and I wanted to clear up any anxiety about the virus.  It will mostly likely not become a big issue in the US.

As a side note, I do NOT intend to cover new infectious diseases forever when the pandemic is over, but may occasionally cover items of special concern.

Mystery hepatitis in children: The suffix “-itis” refers to swelling or inflammation in the body.  The term “hepatitis” refers to swelling or inflammation of the liver.  There are several Hepatitis viruses, (A, B, C, D, and E) but these viruses are not related to each other, and having hepatitis does not necessarily mean that you have one of these viruses.  It can be caused by other things.

A few weeks ago, hundreds of children in countries all over the world had sudden onset hepatitis.  So far, 11 children have died and medical care was necessary for many, including liver transplants.  None of the children had an infection of a Hepatitis virus.

Testing showed that many but not all patients were infected with an Adenovirus upon examination.  Adenovirus infections are very common, and usually have no symptoms, so are often not addressed medically.  Some adenoviruses can cause common cold like symptoms.

So far, 20 individuals tested have had a history of COVID infection, and most individuals were NOT vaccinated against COVID, so at this point, a connection to COVID or a COVID vaccine seems unlikely.

All this to say, the cause of these cases is still unknown, but many in the medical community are currently speculating that they are related to Adenovirus type 41.  At this point, there is no reason for general concern about hepatitis in children, but I will certainly let you know if this changes.

If you or your child experience any of the following, especially in combination, seek medical attention immediately, at least a phone call to your doctor:

Nausea
Abdominal pain
Vomiting
Diarrhea
Jaundice (yellowing of the skin)

Don’t fear, but be smart,

Case Update, May 6th, 2022; Yet Another Omicron Sub-Variant, New Drug Paxlovid.

This is a case update.  I’ll also give an update on new Omicron variants and briefly discuss a new anti-Coronavirus drug, Paxlovid.

In the US, cases continue to increase modestly, and may have peaked.  This increase in cases are likely due to Omicron sub-variants BA.2 and BA.2.12.1 (more on these later). However, new deaths are still decreasing.  I will caution that a rise in new deaths often trails new cases by 2-5 weeks. For the first Omicron wave, deaths followed cases by 2 weeks, and we are currently 4 weeks in to the BA.2 wave.

New Omicron sub-variants, BA.2 and BA.2.12.1: BA.2 has been well known for a few weeks.  I’ve stated before that BA.2 is very similar to the first Omicron variants, and predicted that it will not have a large impact.  A new variant BA.2.12.1 likely falls into the same category.  These variants now dominate the current cases with 98% of new cases being due to one of these variants. 

From the CDC page on Variant Proportions. Accessed May 6th, 2022.

These variants are more infectious than the first Omicron sub-variants, but it is still unknown if they are more or less pathogenic.  Viruses tend to become more infectious and less pathogenic over time.

Some Eastern states like New York were the first to see modest new waves due to BA.2.  New York has yet to see a significant increase in deaths.

From Worldometer, Daily New Cases, New York State.
From Worldometer, Daily New Deaths, New York State.

All this to say, for now, the BA.2 and BA.2.12.1 wave still appears to be somewhat insignificant.

If you had COVID from mid-December to now, you probably had Omicron.  Because BA.2 and BA.2.12.1 are very similar to Omicron, you should not be concerned about reinfection until a significantly new variant arises.  Some people who had Delta have also been infected with Omicron.

Omicron sub-variants get a lot of press, much more than previous sub-variants.  I’ll let you guess why that is. For now, don’t be alarmed about a new Omicron sub-variant.  They will probably all fall into the “don’t stress about it” category.

The pandemic isn’t quite over. If you don’t have immunity, you may want to continue to take precautions by wearing an N95, KN95, or KF94 when indoors in public. Cloth masks or blue surgical masks will not protect you from Omicron variant SARS-2 viruses.

Paxlovid:  2 friends of mine got COVID just this week.  They were both prescribed Paxlovid, a new anti-SARS medication.  The drug is a protease inhibitor, which prevents viruses from maturing as they are formed inside a human cell.  Protease inhibitors do not prevent infection, but they can significantly reduce viral load and improve symptoms.  Both of my friends are doing well now, one feeling significantly better within just 24 hours.  2 people is a very small sample size so this should not be taken as an endorsement. I’m just pointing out that there is a new therapeutic available.

I will point out that Paxlovid is a Pfizer product.  For some, this will cause concern because Pfizer has lost significant trust due to the vaccine mandates and the attending creepiness.

Don’t fear, but be smart,
Erik

Important Update on Paxlovid, from July 2nd, 2022:

This is a post about Tony Fauci’s time with COVID and the drug Paxlovid, which I have discussed in the past.

On June 15th, a story came out about Tony Fauci having contracted COVID, despite having been fully vaccinated and boosted. I didn’t cover this before since I’d already discussed the fact that the vaccines don’t prevent infection by Omicron variants.

However, something else very interesting happened. Dr. Fauci took Paxlovid, which I’ve discussed briefly before, and became COVID negative. But after his 5 day course, he became positive again with worse symptoms. This means that a standard 5 day course of Paxlovid will not necessarily reduce your viral load to zero, and patients may experience “Paxlovid rebound”. Fauci even claims that this kind of rebound with Paxlovid is starting to be seen as “typical” as more patients use it.

The CDC actually issued a warning about Paxlovid Rebound in May, but it was not widely reported.

With so many rebound cases, it’s likely that 5 days is not adequate to eliminate all viruses from the system, allowing rebound. However, Paxlovid does have side-effects, so don’t take it for more than 5 days without consulting your doctor! Hospitals are now only prescribing Paxlovid to high risk patients.

Whenever taking anti-viral or anti-bacterial medications, always take the full course of treatment. If any virus or bacteria survive treatment, they may give rise to a more resistant strain. Don’t just stop your treatment when you feel better. I take anti-biotics as a last report, but when I do, I take the full course. I even made a doctor give me the full 10 day course when she just wanted to give me a half course!

Just to repeat the point on the vaccines, I still hear ads on the radio encouraging vaccination. At this point, the vaccines are really not doing anything against the current COVID variants. There is really no benefit to getting a vaccine or a booster. If you haven’t had COVID yet, I would simply recommend preventative measures. Wear an N95, KN95, or KF94 mask when indoors in public. Cloth and surgical masks will not prevent infection.

Don’t fear, but be smart!

Case Update, April 20th, 2022; Mask Mandates End on Airplanes

This is a case update.  I’ll also have a comment about the recent end of the mask mandate on airplanes.

The BA.2 variant is now causing a very modest uptick in cases in the US.  93.4% of cases in the US are now caused by BA.2, some caused by a new subvariant called BA.12.1.  Most of the uptick in cases in the US is driven by a rise in cases in Northeast states like New York, New Jersey, Massachusetts and Vermont.  Cases remain flat in the rest of the country.

In California, we may be seeing a rise in cases, but reporting has become sporadic, so it’s hard to say for sure. Some days show zero new cases.

World wide, cases are dropping quickly, reflecting the drop in Omicron cases in many countries.

Graph is by me, from data collected from Johns Hopkins University COVID site. Graph is presented in a linear format.

A friend of mine pointed out to me today that more COVID is being detected in waste water, suggesting another upcoming wave.  The only authoritative looking story I’ve seen on this is out of date, from mid-March, so I don’t know how much of an impact this will have.

Mask mandate ends on planes: On Monday, a federal judge struck down the mask mandate for airplanes and other transportation.  The judge ruled that the mandate exceeded the CDC’s authority under the Public Health Services Act. Within hours, the news was announced to cheers on aircraft across the country. I’m sure flight attendants are happy to have fewer arguments with passengers!

I was actually all for the mask mandate for most of the pandemic because I traveled a lot and it was kind of alarming to be on a full plane during COVID.  I did find it troubling, however, that the mandates allowed nearly useless masks like the blue surgical masks, and did not require the much more effective N95s, KN95s, and KF94s. Why require masks if you aren’t going to require useful masks?

In my last several trips, just in the last few weeks, I went into restaurants, hotel lobbies, stores, gas stations, and everywhere else.  The only places still requiring masks were airports, airplanes, and some laboratories.  This is especially ironic since the air on an airplane is HEPA filtered and is some of the safest air you will encounter in your life.

Omicron is the last gasp of the pandemic, and cases are now very low.  Some estimate that 90% of the American population now has vaccine mediated or natural immunity.  I am now in favor of ending the mask mandate on airplanes.  If you need to travel by air, haven’t had COVID yet, and are concerned about getting COVID on the plane, I strongly encourage you to wear an N95, KN95, or KF94 while you travel.  Don’t bother with a cloth mask or blue surgical mask.

Also, as I’ve stated before, studies now show that vaccine effectiveness drops after 3 months. Also, those with multiple vaccinations, more than a few months old, are now 3x more likely to get an Omicron infection than those who haven’t been vaccinated. For details, see my March 25th post. This is because of Antibody Dependent Enhancement. So if you’re in a high risk category and were vaccinated more than 3 months ago, consider getting a booster. Consult your doctor when making medical decisions.

Case Upate, April 8th, 2022; Pfizer Docs Released

This is a case update.  I’ll also talk about a report from Kim Iverson from The Hill regarding finding in the trove of documents release by Pfizer in March and April.

Cases are currently flat in the US.  During the Omicron wave in December and January, the US lagged behind cases in the UK by 2 weeks.  While the Omicron subvariant BA.2 produced a wave in the UK, it has not yet produced a wave in the US, despite it being 5 weeks since the BA.2 wave started in the UK.  I’m going to go out on a limb and say that the slowing of the decrease of cases in the US is all we are going to see of the BA.2 wave in the US. I’ll let you know if this changes. BA.2 cases now constitute 72% of cases in the US.

XE variant: Just a few days ago, news emerged of a new COVID variant called XE in the UK.  The variant is a hybrid of Omicron variants BA.1 and BA.2 and is more transmissible than BA.1.  Since XE is very similar to other Omicron variants, I don’t expect it to cause a large wave of cases in the US.

Pfizer Document Analysis from Kim Iverson: Kim Iverson of The Hill released a video claiming that newly released documents from Pfizer confirm what many knew already.  The shocking claim is that Pfizer has known the following for a long time:

  1. Natural immunity is as effective as vaccine mediated immunity.
  2. The rate of adverse events is at least 10/100,000 (33,000 for the US population). It’s unclear from Iverson if this is just for Myocarditis or for all adverse events.
  3. It is unknown if the reproductive systems of women are impacted by vaccination.  This contradicts public claims that vaccination does not affect reproduction.
  4. A more severe case of COVID triggered by Antibody Dependent Enhancement could not be ruled out.  The Lewnard et al paper a surveillance report from the UK have confirmed that higher Omicron infection rates in vaccinated people are likely due to ADE.  As far as I’ve seen so far, ADE has not lead to more severe cases.

The documents were obtained because of a Freedom of Information Act (FOIA) lawsuit which required the FDA to produce the documents.  Yes, this means that the FDA has had this information and did not disclose these conclusions to the public, instead often releasing information which contradicted these conclusions.

There will continue to be more document releases every month until the end of the year.  There will likely be more bombshells, but most of the releases will simply confirm what people have suspected for months but couldn’t prove.  I will discuss the most interesting, but not all of these releases.

Request for Priority Review
Sorry, I couldn’t find the link to the consent form.

If you have risk factors like obesity, age, or respiratory problems, you should consider getting a booster.  Also, as I said last week, since vaccine effectiveness is substantially reduced after 3 months, those who have been vaccinated with risk factors will need to get a booster every 3-6 months.  Try and find a provider who will aspirate before injection!  There is no medical reason for someone who has had Omicron or Delta variants to get vaccinated or a booster. Talk to your doctor when making medical decisions.

I am posting about every 2 weeks now instead of every week.  I’ll likely post even less unless interesting news comes out.

Case Update, March 25, 2022; BA.2 cases in Europe, Persistence of Vaccine mRNA in Lymph Nodes, Higher Omicron Infection in Vaccinated individuals in UK

This is a brief case update. I’ll also make some more comments on BA.2 related waves in Europe, a new paper suggesting that vaccine mRNA persists in the lymph nodes. Also, new evidence from the UK suggests that vaccines lose potency after 6 months and certain vaccinated individuals are more likely to be infected than unvaccinated people.

Cases continue to go down in the US, although the rate of decrease is slowing.  As you’ll read below, some suspect that an Omicron variant, BA.2, may cause cases to rise in the US.

More on BA.2: I have commented on BA.2 before.  This variant is a version of the Omicron variant, which is slightly more infectious than Omicron itself.  It continues to follow the general trend of new variants being more infectious than older ones. Like the original Omicron, equal portions of B.1.1.529 and BA.1.1, BA.2 has a low fatality rate as compared to previous versions, including Delta. 

I originally held that BA.2 is not particularly interesting because of its similarity to the first Omicron strains.  This still may be true, but some countries like the UK and the Netherlands have seen significant new peaks after BA.2 became prominent. BA.2 is likely contributing to rising cases globally.

Right now in the US, BA.2 is increasing in prevalence, and is currently 1/3 of SARS-2 found in the US.  It’s similarity to previous Omicron versions means that it is displacing B.1.1.529 and BA.1.1, just like Omicron displaced Delta before it. We now have 0% Delta in the US.

From the CDC page on Variant Proportions. Accessed March 25th, 2022.

Currently, new case numbers in the US are still going down, although the rate of decrease is slowing.  John Campbell, a physician and COVID commentator in the UK, argues that a new peak in the US due to BA.2 is inevitable, and he may be right.  But we aren’t seeing it yet.  We may see it the next few weeks.  Campbell also argues that “cases”, the number of infections recognized by the NHS, is much lower than actual infections.  This is certainly true, but we can’t know how many infections there are, since they aren’t reported. This was almost certainly true in the US as well during the Omicron wave.

Does BA.2 significantly change the picture?  I still say no, since the fatality rate with BA.2 is still very low, perhaps even lower than with other Omicrons.  We may or may not see a significant BA.2 wave, depending on how many Americans already have resistance to BA.2. If you had Delta or Omicron, you almost certainly won’t get BA.2.  Vaccination is only partially effective against Omicron variants.

Most people in my area, northern San Diego County, are basically going back to normal.  This is warranted for most.  If you have risk factors like age, obesity, or respiratory issues, you will want to remain vigilant and consider a booster.  I do not recommend a booster for those without risk factors, and certainly not for those with natural immunity.  Talk to your doctor when making medical decisions.

mRNA and Spike Protein Persist in Lymph System for up to 8 weeks:  The Journal Cell just published a paper (Röltgen et al) which argues that mRNA and spike protein are present in vaccinated individuals for up to 8 weeks after vaccination. Cell is the third most highly respected journal in cell and molecular biology.

The cells in your body are surrounded by a fluid called “interstitial fluid”.  This fluid carries nutrients from nearby blood vessels to your cells, and also carries waste back to the blood vessels.  The lymph system is a one-way circulatory system that carries excess interstitial fluid from the extremities of your body back to veins near your arm pits.  On the way, they pass through the lymph nodes, a biological filter and part of your immune system that checks for invading particles. 

The Röltgen et al paper suggests that vaccine mRNAs from the interstitial fluid collect in the lymph nodes and can persist there for many weeks.  They continue to produce spike protein during this time.  Remember that vaccines are intended to be given in an intra-muscular manner, meaning that they are intended to be injected to a muscle and stay there.  This paper shows that they are able to migrate to the lymph nodes. 

The paper does not discuss the medical importance for this in terms of adverse events.  Given the relative rarity of adverse events, I would guess that the presence of vaccine mRNA does not produce adverse events, and that these events are caused by vaccine injection into a vein. Again, the data is not conclusive on this, so this is just my guess at this point.

mRNA technology note:  At this point, I have no evidence to suggest that the problem with the new vaccines is the mRNA technology.  In my estimation, the likely reason the new vaccines lead to adverse events is that they produce the SARS-2 Spike protein which likely causes inflammation throughout the body.  This may only be in vaccine recipients who receive a vaccination in a vein rather than an intra-muscular injection.  If you choose to get a vaccination or booster, ask the health care provider to aspirate before injection.

Certain vaccinated individuals are more likely to be infected by Omicron than the unvaccinated:  A UK surveillance report shows that vaccine effectiveness against symptomatic Omicron infection goes from around 65% effective soon after 2 doses of vaccine, to around 5% 6 months later.  Protection from hospitalization goes down to just 35% after 6 months. These findings suggest that to maintain full protection against Omicron, a vaccinated person will need to get a booster every 3 to 6 months.

From UK Surveillance Report, March 17, 2022, Table 1b. Effectiveness of Pfizer vaccine at preventing symptomatic COVID infection after 2 doses, and after a Pfizer or Moderna booster.
From UK Surveillance Report, March 17, 2022, Table 2b. Effectiveness of Pfizer vaccine at preventing hospitalization after 2 doses, and after a Pfizer or Moderna booster.

In another finding from the report, people with 3 doses of vaccine are 3x more likely to be infected with Omicron than unvaccinated individuals.  This is the clearest evidence yet that Omicron may be using Antibody Dependent Enhancement (ADE) to infect people. The Lewnard et al paper from a few months ago has a similar finding.  For both studies, a certain number of vaccine doses are more likely to increase the chance of infection.  If viruses are using the ADE pathway, this effect would be explained more by the timing than by the number of doses per se.  For ADE to work, a person needs to have a mediocre immune response to an agent, not a strong or weak one. Since we know vaccine mediated immunity goes down over time, then a person becomes more likely to be reinfected as their immune response goes from strong to mediocre.

From UK Surveillance Report, March 17, 2022, Table 13. New case rates among UK residents with at least 3 doses of vaccine, and with no vaccination. Numbers are normalized for the percentage of people in each group.

So should you get a booster? Again, if you have risk factors like age, obesity or respiratory problems, you might want to get a booster every 3 – 6 months. Otherwise, you may choose instead to just take extra precautions as Omicron cases continue to fall in the US. If you choose to get a booster, ask them to aspirate before injection. Talk to your doctor when making medical decisions.

I know this is all very complicated.  Your questions will help me make this more clear.

Don’t fear, but be smart,
