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.

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.

‘Genetic optimization’: Embryo ranking treats children as marketable goods, critics warn

An embryo screening service is drawing sharp criticism from scientists, ethicists and faith leaders who say the technology turns parents into shoppers and children into products.

Manhattan biotech startup Nucleus Genomics is marketing its Nucleus Embryo platform as a tool for genetic “optimization.” It allows couples undergoing in vitro fertilization to upload and rank DNA from up to 20 embryos based on potential intelligence, anxiety, addiction risk and more.

Embryos can come from whichever egg and sperm sources were used in that cycle.

For a minimum of $5,999, parents can receive “polygenic risk scores” estimating the likelihood that their future children will develop diseases such as Alzheimer’s or diabetes or possess traits such as high IQ, low BMI, anxiety resistance or a particular eye color.

“Every parent wants to give their children more than they had,” Nucleus Genomics posted on X alongside a promotional video showing a dashboard where users can sort embryos by projected traits.

To some critics, however, the premise behind the tool is less about love and more about control.

“For some parents, it looks for things like the potential for diabetes, the potential for deafness, conditions that are treatable or healable with today’s modern medicine,” Emma Waters, policy analyst for the Center for Technology and the Human Person at The Heritage Foundation, told The Washington Times.

“But in many other cases, the ones that are equally if not more disturbing, parents are actively using this technology to select children that are the smartest, have a certain personality, are the right sex or otherwise fit their model image of what a child should be — whether that’s blue eyes or blond hair or something else,” Ms. Waters said.

Federal Employee Charged With Capital Murder For Slipping Abortion Pills Into Girlfriend’s Coffee

A 38-year-old Texas resident and federal employee was arrested and charged for killing his preborn child by feeding his girlfriend abortion-inducing drugs without her knowledge.

The Austin-American Statesman reported that Justin Anthony Banta was arrested June 6 and charged with capital murder and evidence tampering. In September 2024, he allegedly snuck abortion pills into his girlfriend’s drink at a coffee shop at about six weeks of pregnancy after she rebuffed his offer to buy “Plan C” for her, saying she wanted the baby.

The girlfriend, who remains anonymous, told police that she began experiencing severe fatigue and bleeding the next day, requiring an emergency room visit, and ultimately lost her baby on October 19.

Police confiscated Banta’s phone during the course of the investigation, accusing him of tampering with it remotely to delete evidence, allegedly using his skills as an IT staffer for the U.S. Department of Justice (DOJ).

“Sheriff Authier expressed his gratitude to the owners and staff of the coffee shop … for their full cooperation, along with the efforts of Parker County Sheriff’s Office investigators, the Texas Rangers, Benbrook Police, Tarrant County Criminal District Attorney’s Digital Forensic and Technical Services, the U.S. Secret Service, the Regional Organized Crime Information Center (ROCIC) and the Federal Bureau of Investigation (FBI) for their support and resources throughout this extensive investigation,” the Parker County Sheriff’s Office said.

In Texas, capital murder is punishable at a minimum of life imprisonment without the possibility of parole, though it is possible prosecutors could seek the death penalty.

Despite the abortion lobby’s framing of abortion as a matter of “choice,” it has long turned a blind eye to abortion coercion.

Live Action’s “Aiding Abusers” series draws on news reports, eyewitness testimony, and undercover video to expose Planned Parenthood employees’ willingness to offer abortions to girls as young as 12 without reporting signs of statutory or forcible rape to law enforcement. This enables the men who brought the girls in for appointments to bring them home and continue abusing them.

In 2023, the pro-life Charlotte Lozier Institute released a study that interviewed 1,000 American women and found that 61 percent of women who undergo abortions do so due to pressure from “male partners, family members, other persons, financial concerns, and other circumstances.”

“Forcing a woman to have an abortion, including a minor, is illegal in all 50 states of the United States of America,” according to the Justice Foundation’s Center Against Forced Abortions, which offers a variety of information resources to help those who are being pressured into killing their babies.

Top FDA Official Admits She Refused the Covid-19 Vaccine While Pregnant

One of the most powerful figures at the US Food and Drug Administration (FDA) has admitted she refused the Covid-19 mRNA vaccine while pregnant—even as her agency promoted it as “safe and effective” for all pregnant women.

Dr Sara Brenner’s explosive disclosure, made on 15 May 2025 at the MAHA Institute Round Table in Washington, DC, is as revealing as it is troubling.

A preventive medicine physician, Brenner has worked at the FDA since 2019. As the FDA’s Principal Deputy Commissioner—and briefly its Acting Commissioner—Brenner was at the centre of decision-making.

Prior to that, she was Chief Medical Officer for diagnostics and was detailed to the White House to support the Biden administration’s Covid-19 response. She didn’t just participate in the pandemic response, she helped shape it from within.

“Knowing what I knew—not only about nanotechnology, about medicine, about the medical countermeasures—but also having a very strong and firm grounding in bioethics…there were many things that were not right,” she told the audience.

That someone with her seniority and access to internal data privately rejected the vaccine, while her agency promoted it to millions of pregnant women, presents a profound ethical dilemma.

Three More States Diverge From CDC On COVID-19 Vaccine Recommendations

Officials from three states said on June 12 that pregnant women should still be able to receive COVID-19 vaccines, diverging from updated guidance from the Centers for Disease Control and Prevention.

Health officials with California, Oregon, and Washington state said in a joint statement that they “continue to recommend all individuals age 6 months and older should have access and the choice to receive currently authorized COVID-19 vaccines, with an emphasis on protecting higher risk individuals, such as infants and toddlers, pregnant individuals, and others with risks for serious disease.”

The CDC in May updated its immunization schedule for adults, removing a COVID-19 vaccine recommendation for pregnant women. Insurers typically only cover vaccines that are on immunization schedules, according to the American Academy of Family Physicians and other organizations.

The CDC also removed a recommendation for healthy children to receive a COVID-19 vaccine, although the childhood immunization schedule states that “where the parent presents with a desire for their child to be vaccinated, children 6 months and older may receive COVID-19 vaccination, informed by the clinical judgment of a healthcare provider and personal preference and circumstances.”

Officials have for several years been directing vaccine manufacturers to update their formulations on an annual basis. The CDC had been advising people to receive a shot each year, regardless of prior vaccination and infection.

Health Secretary Robert F. Kennedy Jr. said the changes were made because there is no clinical data to support a “repeat booster strategy.”

White fibrous clots found in 3-year-old child born to mother who was covid vaccinated while pregnant

Examination of a 3-year-old child’s blood reveals the alarming discovery of fibrous clots in the blood of young children born to mothers who received covid mRNA “vaccines” during pregnancy.

Also, a provisionally accepted paper shows that covid-vaccinated women receiving IVF treatment are less likely to have a live birth compared to unvaccinated women.

Yet, with possibly the exception of the USA, health “experts,” medical organisations and corporate media around the world continue to assert that covid vaccines are safe for pregnant women and their unborn children.

Dr. Kevin McCairn is a systems neuroscientist who has been researching the effects of the SARS-CoV-2 spike protein and its potential to cause prion-like conditions.

In April, Health Alliance Australia hosted a webinar where Dr. McCairn detailed his ongoing research and its implications for public health.  He discussed the presence of amyloidogenic peptides (peptides are the building blocks of proteins) and prion-like particles in blood clots associated with the SARS-CoV-2 spike protein bioweapon found in the virus and the covid “vaccines.”

Dr. McCairn’s analysis of the unusual fibrous white clots, retrieved from the deceased, shows them to be diseased, proteinaceous tissue, primarily misfolded fibrin that is highly amyloidogenic.  His research indicates a potential global health crisis due to these misfolded proteins causing multi-organ dysfunction, neurodegeneration, cancer, heart disease and other health issues.

Ninety per cent of blood samples sent to Dr. McCairn contain these amyloidogenic peptides.   He warned that these prions remain active even months after removal from the body, raising significant concerns about blood transfusions and other medical procedures.

As Health Alliance Australia’s Jeanee Rose Andrewartha said, “We have a global amyloidogenic health crisis. These amyloidogenic prion-triggering epitopes [part of an antigen, eliciting an immune response to an invading pathogen] and peptides are also seated in the environment as well as in living organisms. They are highly resistant with the potential to cause multiorgan dysfunction, neurodegeneration, cancer, heart disease, sudden death, strokes, etc.”

RED ALERT: Doctors Sound the Alarm After Fibrous Clots Discovered in Young Children Born to COVID-Vaxxed Mothers

Top medical experts are raising alarm bells over the discovery of fibrous, prion-like clots in the blood of young children born to mothers who received the COVID-19 mRNA injections during pregnancy.

Dr. Kevin McCairn, PhD – a respected systems neuroscientist with over 25 years of experience in neurodegenerative disease modeling – has published explosive findings that could shatter the mainstream narrative surrounding the so-called “safe and effective” COVID vaccines, Slay News reported.

His new sentinel report contains what is believed to be the first-ever documented case of amyloid fibrils—a misfolded, prion-like protein—in the blood of a chronically ill 3-year-old child exposed in utero to Pfizer’s mRNA shot.

According to PubMed, amyloid fibrils are insoluble protein aggregates associated with deadly neurodegenerative diseases like Alzheimer’s and Parkinson’s.

These fibrils were detected in the child’s blood using Thioflavin T staining, a specialized fluorescent dye. The structures showed alarming signs of misfolded fibrin — a pathological variant linked to abnormal blood clotting and systemic inflammation.

Japan Has Created the First Artificial Womb in the World

Researchers in Japan are developing artificial womb technology, a groundbreaking innovation that could change how we care for premature infants and even reshape the future of childbirth.

This isn’t science fiction—it’s a reality scientists are working toward, and Japan is leading the way.

Let’s explore what this technology is, how it works, and what it means for the world.

What Is Artificial Womb Technology?

An artificial womb is a device designed to mimic the environment of a natural womb. It provides a safe, controlled space for a fetus to grow outside the mother’s body.

The system uses a fluid-filled chamber that acts like amniotic fluid, along with machines to supply oxygen and nutrients through the umbilical cord.

In Japan, scientists have tested this technology on animals like goats and sharks, successfully keeping embryos alive for weeks.

For example, researchers at Juntendo University sustained goat fetuses for up to three weeks in a plastic tank filled with artificial amniotic fluid.

This is a big step toward using the technology for human babies, especially those born extremely premature.

The goal is to help babies born before 37 weeks, who often face serious health risks.

According to the World Health Organization, 15 million babies are born prematurely each year, and 1 million die due to complications.

Artificial wombs could offer a lifeline by allowing these infants to continue developing in a womb-like environment, improving their chances of survival and healthy growth.
