Another absolutely horrible take by #FireWalensky, @CDCgov

“If you go two years without getting that infection, without getting that protection from infection and then all of a sudden, boom, everybody from zero to three years gets RSV, you see the impact on health care.”
Except. That's NOT WHAT the data shows

As we can see, the biggest spike is in 0 to 6 months, and in comparison to 2018-2019, it is much greater. Roughly, per 100k, 130 versus 70, and it is still spiking.

Second biggest spike is in 6 to 12 months, at almost 80, versus 30 at
its highest.

In the 1 to 2 year olds, almost 40 this year vs. almost 20.
(The Y-axis is higher this year because of more cases).

If what Walensky is saying was true, we'd expect to see the 2 to 4 year olds screaming higher.

It's not.
But the big hitter was the zero to 6 months. What happened there?

Walensky's immunity silliness simply is irrelevant.

But this is relevant:
She really will do everything in her power to minimize CoVid, won't she?

RSV dashboard is here - play with it, see what else you can find

cdc.gov/rsv/research/r…
This is Jose Romero, director of the NCIRD at the @CDCgov.

Jose is not thinking clearly. Has he been infected?

Why do I say he's not thinking clearly?
At the most recent CDC briefing, Jose was asked, why RSV is spreading so quickly and early.
"So we’re seeing more RSV because in the last past two years, we’ve not seen infections in children as we have previously. And so these children, if you will, need to become infected to move forward because it’s a disease very common in children. "

Literally, the XKCD comic.
But the same problem exists.

The biggest spike in hospitalizations is in the babies. 0-6 months and 6 months to 2 years. And the 0-6 months was the BIGGEST spike.

What could cause hospitalizations in that group?

Well, first what causes RSV hospitalizations?

"Pre-F antibody titers were significantly lower in mothers whose infants were hospitalized with RSV bronchiolitis compared with those mothers whose infants were not hospitalized..."

academic.oup.com/jid/article/22…
So, maternal antibodies are important. Could the maternal antibodies have not been passed on because the mother did not get infected?

Fortunately, 95% of people are exposed by the time they are two, so the mother would not have had to be exposed to pass on those antibodies.
Can you imagine?

"Now that you are pregnant, let's schedule your infections. First trimester, we'll do RSV and Ebola."

Silliness.

Let's take another look at that preprint that @fitterhappieraj found

Every infant inherits their microbiome from their mom, and mom's
microbiome diversity was reduced by Covid.

And we know those infants had a unique microbiota, per above, compared to Covidians (those infected).

Indeed, SARS-CoV-2 infections during pregnancy are associated with a compromised initial microbial seed of the infant.
No big deal, right?

Wrong.

"The inherited microbiome exerts marked effects on immune programming with long-term health consequences, including susceptibility to infections or chronic inflammatory diseases and reduced vaccine efficacy"
"Therefore, this “window of opportunity” at birth, either renders infants with a healthy immune system or alternatively establishes a divergent path leading to severe immune-mediated disease susceptibility (16-24). "

Well, that sounds like pediatricians are going to be busy.
To be crystal clear, this study is NOT saying that Covid is responsible for the increase in RSV.

But it is saying Covid causes negative changes at a very important moment in the baby's life, immunologically speaking.

And since we are talking about more severe RSV cases?
It seems to be directly related.

Or, at the very least, much more plausible than a concept invented last year. A concept that Fox & Friends has been pushing.

Was it bleach they last pushed? Or herd immunity?

In any event, both Walensky and the director of the CDC are also
pushing immunity debt like universities pushing student loan debt.

Someone needs #FireWalensky, and put Jose on notice.

@CDCgov? That microbiome spoiled once #FireWalemsky got hold of it.

Maybe probiotics could save the #xkcdCDC. Maybe.
The RSV surge in the 0-6 month old babies, which eliminates "immunity debt/gap" as a viable hypothesis?

Will have very real consequences down the road. This is not surprising given measles ability to wipe out immune memory

Now, this is a very interesting PREPRINT.

We've all heard that shingles vaccination reduces risk of Alzheimer's.

And we all know that Covid increases the risk of Alzheimer's by 50-80%.

What happens when you mix them? Will the vaccination offset a different disease?

/1 Opposing effects of SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination on the risk of late-onset Alzheimer disease  View ORCID ProfileCarly M. Rose, Shiying Liu,  View ORCID ProfileWilliam S. Bush, Jonathan L. Haines, Scott M. Williams,  View ORCID ProfileDana C. Crawford N3C Consortium doi: https://doi.org/10.64898/2026.01.21.26344555 This article is a preprint and has not been peer-reviewed [what does this mean?]. It reports new medical research that has yet to be evaluated and so should not be used to guide clinical practice.
Yes.

But by how much? Conclusions and Relevance SARS-CoV-2/COVID-19 infection and recombinant zoster vaccination are modifiable risk factors for LOAD among older individuals, with a modestly significant interaction between the two. Recombinant zoster vaccination reduced LOAD risk regardless of sex and race, though the protection is greater in those without documented COVID-19 infection. Recombinant zoster vaccination and reduced exposure to COVID-19 infection in the later decades of life reduce the risk of developing Alzheimer disease over at least a five-year period.
Useful for below - "Late-onset Alzheimer disease (LOAD; onset age ≥65)"

"odds of LOAD are 16% higher among those with at least one reported COVID-19 infection" Image

A doctor complaining about wearing N95s? Thread foreshadow in the gif 👇.

Dr. Sax, you should read this.

The arrogance of medical doctors thinking they know better than the CDC NIOSH and OSHA?

This comes as no surprise.
Imagine if an asbestos worker, or a tech working in BioSafety Lab was complaining about this.

But somehow, doctors making over $200,000 get carte blanche and and a piece in the @NEJM Voices.

And he does have a loud voice.
This is Dr. Sax, Clinical Director, Division of Infectious Diseases (ID), at THE Harvard hospital. In 2014, he wrote about how ID docs only make $174,000.

He probably makes northwards of $269,000.

This is very, very relevant.

You see, he is put out by the inconvenience Image

From the ZeroCovid sub on Reddit.

How DO we do it?

Hyper vigilance, constant exposure calculations, discussing and taking precautions?

How do I do it?

Quick thread. I would like to hear covid conscious folks opinions on this:  I have long covid (mecfs + pots + mcas). I’ve been sick to varying degrees since 2022. My life has been severely affected by this. At this point, I can’t work. I am mostly housebound, recovering slowly but I still have to spend some days in bed. Recovery from this is awful, especially because it’s not widely understood.  With all that said. I still feel like, for me, a life full of hyper vigilance, constant exposure calculations, discussing and taking precautions…I can’t do it. I don’t want to live that way.  How can I approach t...
I don't do it.

I don't do exposure calculations.

I don't have hyper vigilance.

I am Vax, Mask, and Relax.

For me, it's just a series of habits now. Drive to the wherever, hit parking lot, put on N95. Get out of car. Stays on until I get back into the car.
A new vaccine comes out? I get it.

I go stay in a hotel?

2nd floor Motel 6 with no shared HVAC (has the PTAC) . Open door/windows for one hour until complete air exchange.

Go through a drive through? N95 on before window is rolled down. Drive away? I roll down both to

After reading a study, and reaching for my phone, if the first thing I do is check to see if I have @'d someone in the past?

That's not a good sign.

I have never @'d them, and this is not directed @ them.

But this IS a debunk thread.

And it starts with who.

Study here. Before you read it?

This thread is about providing context. Read the thread, @SalvMattera's comments, AND THEN, read the study.

0/10 from me.

Who paid for it? The Dutch government - who has been spectacularly almost Tegnell-like in their downplaying of LongCovid and masks.

Lead authors are from RIVM, their CDC.

RIVM was antimask even when they FINALLY recommended masks in OCTOBER 2020.

Oh, we are cooked. Just cooked.

"Brain Mitochondrial dysfunction, known for ~20 years is finally recognized as a central upstream driver of Alzheimer’s disease (AD), not just a downstream effect."

And SARS2's targeting of mitochondria is well-known.

Even in the brain.
/1 We identified dysregulation of mitochondrial and synaptic pathways in deep-layer excitatory neurons and upregulation of neuroinflammation in glia, consistent across both mRNA and protein. Remarkably, these alterations overlapped substantially with changes in age-related neurodegenerative diseases, including Parkinson’s disease and Alzheimer’s disease. Our work, combining multiple experimental and analytical methods, demonstrates the brain-wide impact of severe acute/subacute COVID-19, involving both cortical and subcortical regions, shedding light on potential therapeutic targets within pat...

@neiljshaw - — a few tips on your excellent article from a clean air advocate

"Consider Wearing a Mask" ?

No, "It is incredibly important to wear a well-fitting mask such as a N95, KN95, or KF94, for the best protection."

You two are doing Image
public health with this article.

Public health is best done with simple clear instructions.

No:
"These masks act as a barrier, reducing the spread of respiratory droplets when people talk, sneeze or cough."

Yes:
"These masks act as a HEPA air cleaner for the face,
cleaning the air of respiratory aerosols when people breathe, talk, sneeze or cough."

The barrier carries the idea of an immovable wall. Unable to be penetrated by things like oxygen and CO2 - which feeds antimaskers.

As an who debunks antimaskers, it is
