PROFILE: Frederik Schaltz-Buchholzer, Assistant Professor at the University of Southern Denmark
An anti-vaccine professor of vaccine epidemiology? Huh.
There's a new phenomenon that is corrupting America's federal public health agencies. Just about any unaccomplished academic shmuck who has a history sucking up to RFK Jr. or Jay Bhattacharya or Marty Makary on social media is now getting a well-paid job bankrolled by the American taxpayer, even when they're woefully unqualified & doing little more than leeching off the teat of hardworking American families. Kevin Bardosh, Aseem Malhotra, and Alex Washburne are notable examples of this phenomenon, all of them chronically incorrect (and often misogynistic) loudmouthed contrarians, desperate for attention.
Frederik is the latest example of such an embarrassment to the medical and scientific academic tradition, desperately auditioning for a shot to get one of these accountability free jobbie-jobs that are paid for by the Trump Administration’s magical money tree. One of the great casualties of the COVID-19 pandemic, the first pandemic in a world connected by social media, is how American-made anti-vaccine propaganda rapidly spreads worldwide, lent credibility by credentialed academics desperate to stand out from the medical and scientific consensus.
What follows is taken from Frederik Schaltz-Buchholzer's Twitter account, "FSBuchholzer," unless noted otherwise.
2021
Frederik Schaltz-Buchholzer decided he would try and make a name for himself as a COVID contrarian early, by abusing his credentials to champion “natural immunity,” an anti-vaccine myth that insists vaccines do not confer “natural” protection to a virus and is thus inferior to simply surviving the virus. This is what is known as the “naturalistic fallacy,” something any serious medical professional should understand.
October 2nd, 2021: “…the strength of natural immunity has been neglected, and should be recognized.”
Well, between all the unvaccinated people who died in pursuit of “natural immunity,” and the people developing serious health complications from repeated COVID-19 infections, it’s clear that this was pure garbage. Off to a great start!
2022
January 16th, 2022: “Vaccination of millions who already had natural immunity, thereby bypassing others at risk of severe covid, was what was "not helpful" and, in fact, harmful. With a death toll.”
Frederik did not provide any evidence for his claim that vaccinating those with “natural immunity” was killing people. Fearmongering about the COVID-19 vaccine is very popular on social media, and Frederik was willing to lend the credentials of the University of Southern Denmark to such nonsense.
Frederik would go on to tweet to two colleagues in the United Kingdom:
March 18th, 2022: “I hope you keep tweeting about the data, including the positive news from Denmark where brave SSI_dk has led the way out of covid hysteria and pandemic delusion.”
Yes, right as over 190,000 deaths were recorded in the United Kingdom, Frederik believed that the most important threat to overcome was “covid hysteria” and “pandemic delusion,” and that a nation of 68.5 million people should have followed the model of a homogenous Nordic country with a population of… six million. "Just copy Denmark” is a popular myth in anti-vaccine circles, propagated by cranks like Vinay Prasad who now sits upon three senior roles at the Food & Drug Administration. Katherine J. Wu debunks this myth in The Atlantic.
June 22nd, 2022: "The real question is whether SARS-CoV-2 should be a vaccine disease or a childhood disease...Many countries chose the wrong route, but then it became a childhood disease anyways because the vaccine didn't prevent infection. (Shrug Emoji)"
Frederik Schaltz-Buchholzer is an Assistant Professor who doesn’t understand the fundamentals of disease or vaccination. Basic medical ethics state that children should have the protection of vaccination before encountering any virus, even if the vaccine doesn't prevent infection. Secondly, a childhood COVID-19 infection does not confer lifelong immunity to the disease. While Frederik was slacking off from his professional duties to scroll Twitter, real scientists have built a mountain of evidence showing COVID-19's impacts on pediatric health and development, of which an updated COVID-19 vaccine confers some protection against:
ANSWERED: Is COVID-19 Harmful to Children?
"A growing mountain of evidence, since 2020, has wildly disproven claims about COVID-19 being harmless in kids. New research now shows that Long COVID is common and has surpassed asthma as the leading chronic illness in children after just a few years of mass, repeated infections. We here at the Pandemic Accountability Index have compiled and organized this peer-reviewed medical research as a handy guide to help correct your misconceptions."
Instead of learning from his professional colleagues, Frederik decided that he should let social media influencers dictate his thinking. Now he wants other people's children to suffer for the fantasy he’s subscribed to: turning a blind eye to these well-documented harms. Such masturbatory narcissism has no place in medicine.
July 25th, 2022: Mr. Schaltz-Buchholzer endorses former PAI Profile subject, Alasdair Munro, and his completely pitiful crusade to establish "Immunity Debt" as common knowledge. Sadly, this would be repeated in mainstream media here in America. If you're unfamiliar, Immunity Debt is a calm-mongering pseudoscientific concept invented in 2021 to lobby against non-pharmaceutical interventions - and can be debunked by opening any basic Immunology 101 textbook.
The University of Southern Denmark is employing an Associate Professor of Vaccine Epidemiology who doesn't understand the basic functions of the immune system.
December 15th, 2022: If hundreds of millions were living with long COVID issues, it would be a 1 in a million coincidence that I don't know even one of them. But there are definitely many that have been heavily affected psychologically by the scary tales of the pandemic.
Frederik constantly cracks jokes and mocks people disabled by SARS-CoV-2 on social media, insisting that it’s all in their heads. Meanwhile, research shows that Long COVID is affecting around 400 million people worldwide.
2023
August 31st, 2023: In a rather misogynistic and depraved statement, Frederik tweets:
"Schools do close as a response to hysteria, that is true. Who brought that upon them?"
Frederik thinks teachers, a predominantly female profession, should have gleefully followed the dozens of educators who died in New York City schools in Spring 2020. For wanting to not die on the job or watching their students suffer as they’re too sick to learn thanks to a brand-new SARS virus, Frederik casually dismisses their real-world concerns as "hysteria." This is indefensible misogyny and immediately disqualifying from any professional or academic setting.
"Oh and the long covid clinics have closed because there were no patients."
Yet again, another boorish dismissal from a man who simply doesn't care. Also, a blatantly untrue and dishonest statement. This is from the Program Manager of The Covid Recovery Center at Brigham and Women’s Hospital in Boston MA:
The truth? We still lack a cure or treatment for the millions worldwide disabled by SARS-CoV-2, and these clinics failed to help these patients, who wind up discharged and written off as “cured” - which Frederik is misrepresenting as Long COVID being no big deal. They're simply "hysterical" in Frederik's eyes, and as we all know, the final word in all of science and medicine that matters is an uninformed man’s opinion.
September 1st, 2023: "Tell me again why a school should close because of some COVID cases among its teachers? Here, they would just call in substitute teachers for the few days that they are sick, as for flu or other possible reasons for absence."
As someone who desperately wants to be seen as an expert on the SARS-CoV-2 virus by repeatedly downplaying its harms, Frederik repeats the tired anti-vax meme that it only makes people sick for a few days and falsely compares it to the flu. In reality, many teachers are now too disabled by COVID-19 that they are unable to teach, and here in America, widespread outbreaks led to teachers being replaced with unqualified National Guardsmen and police officers.
On top of this, many children are now too sick to attend school regularly. Mr. Schaltz-Buchholzer clearly does not care about children's health or education. He cares about trying to impress anti-vaccine celebrities by repeating their lies, lending the credibility of the University of Southern Denmark to their reactionary mythology.
2024
Jan 6, 2024: “…adolescents should never receive an mRNA vaccine again until an RCT has documented that it is beneficial for their overall health.”
Fearmongering about lifesaving mRNA technology is another tired anti-vaccine meme. Does Frederik have a single thought in his head that didn’t come from a social media influencer in COVID contrarian circles?
April 8th, 2024: “While we've known about natural immunity since the Athenian plague, the recently proposed concept of "hybrid immunity" was first introduced in the scientific literature in 2021: I have not seen dispositive evidence that "hybrid immunity">natural immunity."
While “hybrid immunity” to SARS-CoV-2 is a myth, so is “natural immunity.” Vaccine-induced immunity is also natural. How does an Associate Professor of Vaccine Epidemiology keep repeating basic anti-vaccine myths, fetishizing viruses over lifesaving vaccines?
Also, Frederik’s claim “we’ve known about natural immunity since the Athenian plague” is yet another tired old myth from anti-vaccine circles. In reality, much remains unknown about this dark chapter of history to make such definitive claims.
2025
Jan 19, 2025: Frederik writes a Sensible Medicine opinion-editorial titled: "The Nomination of Robert F. Kennedy Jr. as Secretary of the Department of Health and Human Services: a new beginning?" and goes on to claim:
"...most vaccines were never adequately tested for their overall health effects,"
This is a complete and total fiction. A supposed professor of vaccine epidemiology should know that vaccines are one of the most studied fields in medicine:
Thus, Frederik is either woefully incompetent or outright lying. Both are grounds for immediate dismissal from the University of Southern Denmark.
March 13th, 2025: Frederik arrogantly repeats another anti-vaccine meme, claiming that PPE such as N95 respirators "were and are completely useless." So just who can we trust? Is the entire field of PPE engineering, including international manufacturers such as 3M and Binax, engaged in a global conspiracy of fraud? Or is this Associate Professor willfully & smugly ignorant about an entire scientific field?
The basic laws of probability would suggest Mr. Schaltz-Buchholzer is neglecting his professional responsibilities as an academic; to practice a certain level of intellectual inquiry, instead of smugly dismissing entire scientific fields outright. In public.
March 31st, 2025: "Champions of public health, who (as opposed to Dr. Jonathan Howard) were correct on the pandemic, has been nominated for key positions. (Jay Bhattacharya for NIH, Makary Makary for CDC)."
This is a completely false statement. Clinking champagne glasses after publishing an online petition didn't help a single doctor treat COVID-19 patients in overwhelmed ICUs. Endorsing the conspiracy theories of scam artist Robert F. Kennedy, Jr. - who blamed random pediatric deaths on the COVID-19 vaccine - didn't keep schools open through COVID-19 outbreaks. If you're this detached from reality, then you have no place serving as an "Assistant Professor," because you've now a professional liability.
"It also seems that there will be a review of the pediatric vaccine schedule in the US, perhaps with a cluster RCT comparing with schedules from other countries (clapping emoji)"
This is a tired old anti-vaccine myth, that Americans are over-vaccinating their children. Regardless, medical science is not a popularity contest - Americans shouldn't vaccinate their children against a disease simply because another country does not. Needless to say, these RCTs have not happened and will never happen.
July 12th, 2025: Robert F. Kennedy, Jr. and his handpicked gaggle of loudmouthed do-nothing quacks, including Jay Bhattacharya, Marty Makary, and Vinay Prasad have completely and totally failed at their leadership roles in the HHS, NIH, and FDA respectively. This is not open for debate: the organizations have been totally compromised, with the remaining staff in open dissent. On a near daily basis, new humiliating headlines come out, showing how these agencies are in collapse. These are essential institutions tasked with safeguarding American lives, and have now been rendered totally non-functional in a matter of weeks, buried in ongoing litigation.
Frederik found reason to celebrate from the comfort of his University office in Denmark, gleefully declaring:
"So far for US public health, what has happened so far? Positive: 1. Discontinuation of unnecessary COVID-19 vaccination of babies, toddlers and pregnant women [green checkmark emoji]"
I’m sure the parents of thousands of American children who would just love to hear Frederik Schaltz-Buchholzer come to their door and smugly explain why their children’s death from COVID-19, overwhelmingly unvaccinated, were "necessary." We still have a steady stream of pediatric COVID-19 deaths rolling in, overwhelmingly unvaccinated. Frederik Schaltz-Buchholzer is a Professor of Vaccine Epidemiology who thinks vaccine-preventable deaths in children are somehow "necessary." No wonder this Little Eichmann is trying out for a job in the Trump Administration.
July 14th, 2025: "Nominating Jay Bhattacharya (NIH), Marty Makary (FDA) and Vinay Prasad all incredibly skilled scientists who I admire that will promote and reform US Public Health like no one else. Any questions?"
Actually skilled scientists worth admiring are doing important work, and this work isn't done by branding colleagues "Covidians," "idiots," and other childish insults for the past five years. In fact, none of these three names were doing any real science, because they were too busy profiting from posting vulgar contrarian garbage on social media and/or mugging in front of a camera:
There's an entire Youtube channel which archives this in extensive detail.
This is the behavior that Frederik "admires:" shitting on his colleagues that are actually taking their responsibilities seriously.
Final Analysis
In his January 2025 article for Sensible Medicine, Frederik wrote: "My prediction? RFK Jr. will be a net positive for public health in the U.S." A bold claim to make about a lawyer with zero medical or scientific credentials, with a long history of exploitative scams and utterly indefensible actions. Frederik has refused to acknowledge that his prediction was immediately proven wrong.
While America's leading public health institutions have been reduced to a sick joke, HHS Secretary Robert F. Kennedy, Jr. is presently focused on ice cream and making obscene claims about the lifesaving Hepatitis B vaccine, falsely blaming it for autism, a decades-old myth. Frederik Schaltz-Buchholzer, Assistant Professor of Vaccine Epidemiology at the University of Southern Denmark, thinks children dying of vaccine-preventable causes like COVID-19 and Hepatitis B is a "net positive."
Frederik Schaltz-Buchholzer is a cautionary tale about how following the herd doesn’t grant immunity to losing all grasp on real-world science. Much like Nick Coatsworth of Australia, Frederik has been reduced to constantly repeating myths he’s heard from his social media echo chamber. When reality penetrates this safe space, Frederik is reduced to childish insults and doubling down.
Needless to say, the University of Southern Denmark didn’t hire someone to sit around and tweet garbage all day. The contact information for the leadership of the department of Epidemiology, Biostatistics and Biodemography can be found here.
Consider asking them if they share Frederik’s view that vaccines which are proven to prevent pediatric deaths to be “unnecessary.”
