Rates of successful conceptions according to COVID-19 vaccination status: Data from the Czech Republic

Abstract

Background

Adverse effects of COVID-19 vaccination on human menstrual cycle characteristics have been observed, but limited data are available on the relationship between COVID-19 vaccination status and birth rates.

Objectives

Therefore, we used nationwide data from the Czech Republic to examine rates of successful conceptions (SCs), that is, conceptions leading to live births 9 months later, for women who were either vaccinated or unvaccinated against COVID-19 before SC.

Methods

Summary monthly COVID-19 vaccination and birth data for women in the Czech Republic aged 18–39 years were retrieved for the period from January 2021 to December 2023. The numbers of SCs per month per 1000 women were calculated for preconception-vaccinated or unvaccinated women, respectively, as well as the number of SCs per month per 1000 women for all women aged 18–39 years.

Results

During the study period, there were approximately 1,300,000 women aged 18–39 years in the Czech Republic, and the proportion of COVID-19-vaccinated women increased from January 2021 until reaching a steady state of around 70% by the end of 2021. At least from June 2021, SCs per 1000 women were considerably lower for women who were vaccinated, compared to those that were unvaccinated, before SC. Furthermore, SC rates for the vaccinated group were much lower than expected based on their proportion of the total population.

Conclusions

In the Czech Republic, SC rates were substantially lower for women vaccinated against COVID-19 before SC than for those who were not vaccinated. These hypothesis-generating and preliminary results call for further studies of the potential influence of COVID-19 vaccination on human fecundability and fertility.

FDA, CDC advisers say lost pregnancies higher than expected following early mRNA vaccination

President Trump’s second-term agenda has been careful not to cast doubt on his signature first-term achievement, the development of COVID-19 vaccines through Operation Warp Speed, which congressional Republicans continue to laud and even claim was sabotaged by Pfizer to deny Trump a consecutive term despite his base souring on the therapeutics.

A new preprint study on mRNA COVID vaccines in early pregnancy, coauthored by top advisers to Trump’s Food and Drug Administration and Centers for Disease Control and Prevention, may fuel the splintering of the Make America Healthy Again movement as the jabs’ opponents ramp up pressure on Health and Human Services Secretary Robert F. Kennedy Jr. to ban them.

Not yet peer-reviewed, the study analyzed hundreds of thousands of Israeli medical records on pregnant women in the three years before and after SARS-CoV-2 emerged in China, finding 43% more “observed-to-expected” fetal losses per 100 pregnancies — 13 instead of nine — when the first mRNA dose is taken between 8-13 weeks’ pregnancy.

Pregnant women who took a booster between 8-13 weeks lost an additional two pregnancies per 100, a “potential dose-response relationship,” the study said.

By using pregnant women who got flu vaccines between 8-27 weeks and women who received either vaccine before their pregnancy as “comparative controls,” the authors said they were able to show the association is unique to COVID vaccines. 

The former had a “consistently lower-than-expected observed number of fetal losses, likely the result of healthy vaccinee bias” – in which people with overall better health tend to have higher vaccination rates – while the latter had “according-to-expected or lower-than-expected numbers of fetal losses,” the study found.

It said “almost all” mRNA doses were made by Pfizer, whose own 2021 report to the FDA – which the agency hid for 16 months until a court made it public – shows 44% of women in Pfizer’s clinical trial lost their pregnancies.

Did Head of CDC Vaccine Safety Office Delete COVID Vaccine Injury Records?

A key official at the Centers for Disease Control and Prevention (CDC) responsible for monitoring vaccine safety and reports of vaccine injuries may have mishandled or deleted official records subpoenaed by Congress, Sen. Ron Johnson (R-Wis.) alleged earlier this week. The New York Post first reported the story on Thursday.

Dr. Tom Shimabukuro, director of the CDC Immunization Safety Office, maintained the records in question. Shimabukuro previously authored a key paper and participated in public messaging claiming the COVID-19 vaccines were safe and effective for pregnant women.

Johnson, chairman of the U.S. Senate Permanent Subcommittee on Investigations, requested the records in a subpoena sent in January to the U.S. Department of Health and Human Services (HHS). The subpoena pertained to an investigation into internal COVID-19 vaccine safety communications.

According to the New York Post, the subpoena led HHS to discover “potential discrepancies” in the emails maintained by Shimabukuro.

“HHS officials recently informed me that Dr. Shimabukuro’s records remain lost and, potentially, removed from HHS’s email system altogether,” Johnson wrote in a letter he sent earlier this week to U.S. Attorney General Pam Bondi, FBI Director Kash Patel and HHS Principal Deputy Inspector General Juliet Hodgkins.

Johnson called Shimabukuro’s possible mishandling of his official records “highly concerning.”

Journalist Paul D. Thacker, a former U.S. Senate investigator, said, “Every American should be concerned about government scientists deleting or hiding federal information to shape a political agenda. That information belongs to the taxpayers.”

Nebraska chiropractor Ben Tapper, whose questioning of the COVID-19 vaccines led the Center for Countering Digital Hate to add him in 2021 to its “Disinformation Dozen” list of the “leading online anti-vaxxers,” said he was “not surprised” by Johnson’s allegations.

“For years, I’ve seen patterns like this before regarding vaccine safety data. The public health establishment often prioritizes profits over people and continuously seems to protect the lies over the truth. The idea that critical records might vanish — whether through negligence or intent — fits a familiar playbook,” Tapper said.

California attorney Rick Jaffe said Johnson’s allegations are “troubling, but not surprising, given longstanding concerns about transparency at the CDC.”

In response to a Freedom of Information Act (FOIA) request last year, the CDC told Children’s Health Defense the agency has no records of certain internal email communications relating to the agency’s follow-up investigation of safety signals associated with COVID-19 vaccines.

HHS, CDC and Johnson’s office did not respond to requests for comment.

Vindication For The Unvaccinated?

At a recent family gathering, I sat at the dinner table with a group of loved ones for the first time since the Covid-19 fiasco. Most of the cheerful discussion focused on the spectacular event of the week: my mother’s 100th birthday. 

I was the only person at the table who hadn’t had any form of flu for many years, while all of the guests had been ill to one degree or another. Almost everyone had tested positive for Covid at least once over the last few years with accompanying flu symptoms. Although no one in my family was hospitalized or died during the so-called pandemic; they all had been vaccinated repeatedly. As far as I know, my wife and I were the only ones in our families who didn’t get any Covid shot, and I haven’t been inoculated for anything in the last seventy years. 

On this happy occasion, the fear, masks, lockdowns, and accusations of the recent past had been mostly forgotten. It was not because the signs and symptoms of the disease had ended, nor that the call for vaccination or testing had been silenced. No one understood why they were still occasionally feeling unwell, with some continuing to report they’d been diagnosed with Covid. 

My view of healthcare has always been outside of the box, having practiced Traditional Chinese Medicine for many decades. I’d worked closely with medical doctors in treating some of their patients and also served as the chief medical officer of a volunteer fire department, appreciating life-saving emergency procedures of modern biomedicine. Through a range of experiences, I gained some knowledge of the causes and cures for suffering and illness.

Before the Covid fiasco, my alternative approach to illness had been respected; I’d shared my knowledge with whoever might ask. My medical perspective was no secret from friends and family. When my daughters were young, they weren’t vaccinated as there were no threats of deadly or debilitating diseases. This was in a place and time when vaccination for infants could be considered and refused, not done by rote. There was reasonable dialogue about the topic — and non-compliance certainly did not elicit threats of excommunication. 

As the specter of a pandemic arose, my opinion about vaccination became dangerous and irrelevant. 

From the outset, it was apparent that the claimed benefits of the new vaccines did not outweigh their risks. I openly said and wrote that the technology remained untested — though never advised anyone to refrain from inoculation — only counseling those who listened to remain fully informed.

It wasn’t complicated. Using genetic-based technology in developing a new drug that attempted to manipulate the magnificent complexity of the human immune system was at a minimum, a gamble. As easily demonstrated, this new technology embraced the bold assumption that human design was flawed and could be improved. It was premature to declare that this experimental treatment was safe and effective. We still don’t know the actual long-term effects — particularly over generations.

This simple and logical evaluation was considered preposterous by those who responded to the seemingly new disease with unbridled fear. The danger of the Covid flu was deemed sufficient to quell all reasonable responses about the risks of the vaccines. Suddenly, there was an eclipse of medical autonomy, and debate was scorned. The actions and motives of corrupted government agencies and their profit-oriented allies in Big Pharma were blessed by devious leaders, who deemed them altruistic and unquestionable. 

This atmosphere, developed and enforced in a haze of authoritarian dictates, created an unprecedented climate of hostility that infected all relationships. Because of my views and unvaccinated status, I rapidly became a pariah to my family.

Early on, when the fear tactics were in high gear, my cousin, who is an attorney involved in healthcare issues, sent a blistering email, condemning one of my first articles skewering the pandemic response. He left no room for dialogue and writing, it is the height of irresponsibility to add to the disinformation that is everywhere about the Covid vaccine. He concluded…

I am really upset that you have chosen to use your talents and thoughtful manner to give credence to the kind of wrongheaded rhetoric and conspiracy theories that feed the mass hysteria over accepting the reality that if we are to beat this pandemic, we need to not just take the vaccine if we want to, but take it on a societal level whether certain individuals want to or not. Your call for “transparency” just further feeds a certain, huge segment of the populations’ belief that they know better than the experts on this issue. They do not. You do not. I do not. But every reputable researcher and medical professional who has reviewed this data agree – it is safe, it is effective, and it is critical.

The venom exuded in response to my unwillingness to join in the mass delusion supporting vaccination was palpable. My crime was unforgivable.

Although we had been very close, all contact ended. However, it was not his unconscious, misdirected anger that troubled me, rather that he shared his views and wrath with my daughters, supporting their inclination to distance themselves from me because of my independent views. This wound with my cousin may never heal.

My mother, who had cordially disagreed with me on vaccination, balanced his bias with sound advice to her granddaughters. She urged them not to be harsh, suggesting that whatever differences they see, these were not worthy of destroying their relationship with their father. Thanks to her wise counsel, the love my daughters and I share has survived.

This and similar events had been left smoldering. In the spring of 2025, at this happy gathering celebrating my mom’s longevity, to my surprise, the topic turned to Covid. (My cousin was not there.) Conversation comprised mostly of personal accounts of suffering and confessions of a lack of understanding of why the virus persisted. 

My sister said she’d attended a lecture at a local college on the history of the social response to mass infection. She described the common human responses and behaviors to past epidemics and pandemics, including how scapegoating was a dominant and destructive response. 

Managing to remain quiet until all had acknowledged these horrors of the past, I spoke up, voicing a simple question: Did the recent Covid pandemic fit this pattern?

Miscarriage and Pregnancy Loss Rates 43% Higher Than Expected After Covid Vaccination, New Study Finds

Dear readers, I am delighted to share with you the fruits of a massive research project I’ve been working on, which is the reason why you haven’t heard from me in a very long time.

I quickly realised after I started working on it that I would have to prioritise it at the neglect of posting here. I got so swept up in it that I didn’t even have time to post about my Process 1 vs Process 2 work. I hope you will agree it was worth it.

I will start with the key findings and then try to explain the methodology in plain language. The paper is based on analysis of electronic health records (EHR) from one of Israel’s largest health insurance funds. For those of you who would rather read the paper itself, here’s a PDF.

Key findings

Here are the key findings (as summarised in a post on X).

Women vaccinated in early pregnancy (weeks 8-13) had a higher-than-expected number of foetal losses:

  • Dose 1 = 3.9 more per 100 women [43% higher than expected: 13 vs 9]
  • Dose 3 = 1.9 more per 100 women [19% higher than expected: 12 vs 10]

Late pregnancy losses were a big part of the signal.

Among all women, 1.1% lost their pregnancy after week 24, compared to 2.7% of women who received dose 1 in early weeks, and 1.8% of women who received dose 3 in early weeks.

The Czech data reveals the truth about the COVID vaccine. Is that why no epidemiologist or infectious disease expert will touch it?

Executive summary

There is no vaccine more important than the COVID vaccine.

And there is only one publicly available database that reveals the truth about the safety and efficacy of the COVID mRNA vaccines: the Czech record level data.

The dataset should be a goldmine for epidemiological analysis—arguably the best available dataset to evaluate COVID vaccine safety and efficacy in a real-world population.

Yet, every epidemiologist and infectious disease expert on earth avoids this database like it was infected with a deadly virus.

AFAIK, I’m the only guy who has analyzed it using an objective, conservative analysis method.

It took a whole hour or so to write the code and run the analysis.

The analysis shows the shots were neither safe nor effective. It’s all crystal clear from the Czech data.

Here’s the cool thing. All you need is one plot. No rocket science degree required.

I’ve asked AI to opine on why I’m the only guy who wants to look at the data.

The smoking gun graph: the one plot that tells the story instantly

Below is the cumulative all-cause mortality (ACM) death counts of everyone under age 80 in the Czech Republic. The cohorts are FIXED composition cohorts defined by whether or not the person was vaccinated as of 6/14/21 (the enrollment date). Source data. The cohorts are naturally matched. No scaling was done or needed.

The Science on Autism and Vaccines Is Not Settled: What Studies Are Missing

Like many physicians, I was taught early in my training that any link between vaccines and autism had been completely disproven—that “the science is settled” and no longer open for debate. I repeated that message with confidence for years. But when I began researching for my book, “Between a Shot and a Hard Place,” I set aside assumptions and took an unbiased look at the data myself.

What I found wasn’t reassuring. It wasn’t the robust body of evidence putting the question to rest. Instead, I found a surprisingly limited collection of studies—filled with narrow designs and major gaps. As a board-certified pediatrician trained at top institutions, I expected certainty. What I found was an unsettled and incomplete landscape—one that calls not for dogma, but for open scientific inquiry and nuance.

Let me be clear: I am not claiming that vaccines cause autism. I am saying, with humility and urgency, that we do not know. And the truth is, no one can say with confidence that we do.

That’s the problem.

The Scope of the Problem

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition. While some children are only mildly affected, many face significant challenges with speech, motor skills, and daily functioning. The spectrum is wide—and growing.

According to the CDC’s latest numbers, 1 in 31 children in the United States is now diagnosed with autism. In California, the numbers are even higher: 1 in every 12.5 boys. While it’s true that changes in diagnostic criteria and increased awareness have contributed to the rise, they don’t explain the increase in severe cases.

Nearly two-thirds of children with autism today have borderline or profound intellectual disability—a rate that’s higher than in decades past. This is a public health crisis. One we cannot solve if we refuse to ask the hard questions about what may be contributing to it.

Japan Releases Bombshell Vax vs. Unvax Data on 18 Million People

A COVID vaccine database covering 18 million citizens has just been released for the first time.

After reviewing the data, a top professor warned: “The more doses you get, the sooner you’re likely to die.”

The most terrifying finding was a deadly spike just 3 to 4 months after the final shot.

Let’s break down the data.

On June 15th, a group of brave Japanese truth seekers did what their government wouldn’t—they released a bombshell broadcast exposing vaccine data from over 18 million people.

Journalist Masako Ganaha posted on X: “If the government won’t do it, then the people should investigate the mass deaths of Japanese people! Database of 18 million vaccinated people revealed for the first time!”

The video featured Member of the House of Representatives Kazuhiro Haraguchi, Dr. Yasufumi Murakami, and the Information Disclosure Request Team.

Dr. Yasufumi Murakami isn’t just some fringe voice. He’s a respected professor at the Tokyo University of Science, where he serves as vice director at the Research Center for RNA Science.

He holds a Doctor of Pharmaceutical Science from the University of Tokyo and has authored over 100 scientific publications.

Tennessee Funeral Directors Association Confirms White Fibrous Clots Are Real and Prevalent

Former USAF Major Tom Haviland joins me to discuss his presentation at the 2025 Tennessee Funeral Directors Association (TFDA) Convention—marking the first time a U.S. state funeral directors association has publicly acknowledged that white fibrous clots are real, prevalent, and ongoing.

Invited by TFDA President Taylor Moore, Haviland conducted an in-person survey with 28 embalmers and funeral directors during the convention in Franklin, TN:

  • 64% reported seeing white fibrous clots in corpses during the first half of 2025
  • The white clots appeared in an average of 17% of all corpses
  • 70% reported signs of micro-clotting (“coffee grounds” or “dirty blood”)
  • 39% of embalmers observed an increase in infant deaths, with an average 14% rise over pre-2020 levels

These results were not only documented on paper but confirmed on video, as multiple embalmers raised their hands during Haviland’s presentation to verify that they had personally observed the white fibrous clots. Many stated they had never seen such clots before the COVID-19 era.

How Much Damage Has Mass Vaccination Done to Society?

My mind often overlaps the past present and future onto themselves. Because of this, I will frequently recall events that happened in the past which perfectly mirror what is unfolding before us, and in turn, I’ve lost count of how many times I’ve witnessed humanity repeat its same mistakes or can see a slow motion train-wreck ahead on the horizon. During COVID, I realized we were again reenacting the same tragedy humanity had ever experienced since the smallpox vaccine was brought to the market and I had a thought. If people became aware of what had happened before and ended our collective amnesia, perhaps this could at last stop.

As fate would have it, my wish came true, and without knowing me, Steve Kirsch gave me the opportunity to begin introducing that forgotten history to the world. This happened after he chose to publish an article I wrote illustrating how the trucker protests were identical to smallpox protests that had happened more than a century before and then for reasons I still do not understand, encouraged his readers to subscribe to me so I would start writing here.
Note: At the time I chose the username “A Midwestern Doctor” (for the smallpox article), I did not put much thought into it as I was never expecting to use it again.

Over the years, I’ve noticed again and again that a vaccine disaster happens which injuries many in a very similar way, it gets swept under the rug (often by officials who are quite conflicted in their decision to do so), and then the same thing happens again a few decades later.

Given that we give dozens of vaccines to each member of society, this raises an obvious question—what is that doing to society?
