Vaccination side effect infertility? 5 Danger Areas of Corona Vaccination [mRNA Injection] for Female Fertility!

Vaccination side effect infertility? 5 Danger Areas of Corona Vaccination [mRNA Injection] for Female Fertility!

The exclusion of infertility due to reproductive toxicity as a vaccine side effect of the mRNA vaccination before the start of the vaccination campaign is still pending. In the following, both the non-existing exclusion and the known risk area of the now obvious vaccine side effects due to reproductive toxicity of the Covid vaccination are explained in detail.

1. No exclusion of developmental and reproductive toxicity as vaccine side effect of mRNA vaccination!

Before clinical studies can be conducted in pregnant women, pharmacological agents must first be tested in pregnant animals. These studies are called Developmental and Reproductive Toxicology (DART) studies.1

1.1 Recommendation for pregnant women based on one single animal study with 44 rats

The basis for clear recommendations on `vaccination` of pregnant women, from organizations such as the American College of Obstetricians and Gynecologists (ACOG)2 is essentially based on one single animal study involving only 44 experimental animals.3 It is now known that Pfizer excluded pregnant and lactating women for all clinical phases and thus did not study potential reproductive toxic vaccine side effects of mRNA vaccination (p. 33, Art. 2h 11).4 Vaccine side effects affecting male reproductive health were also not conducted at any time, and actual and potential risks to that effect are fully addressed in this article.

1.2 BioNTech package insert does not provide a data basis to exclude vaccine side effects in pregnant women

In the package insert of the active ingredient from Pfizer-BioNTech, the following is written (as of 12/2021): " Available data on COMIRNATY administered to pregnant women are insufficient to inform the risks associated with the vaccine in pregnancy."5

For this reason, in order to record possible vaccine side effect, the same package insert asks 'vaccinated' and pregnant women to enroll in a registry called 'MotherToBaby'.6 to participate in an observational study.

Thus, the studies on pregnant women have been conducted since the beginning of the vaccination campaign - `live` on the population, with the more than alarming vaccine side effects in the form of pregnancy complications and miscarriages being dealt with in detail in another article.

1.3 No recommendation for pregnant women according to the British government

Also on the UK government website, regarding the active ingredient BNT162b2 as of August 16, 2022, in section 3.47 also correctly advises against injection for pregnant women and breastfeeding mothers due to the lack of safety data on the reproductive toxicity of Covid vaccine.

"The basis for clear recommendations to "vaccinate" pregnant women ... is essentially rooted in a single animal study involving only 44 experimental animals."

2. One flawed and corrupted animal study to exclude vaccine side effects.?

To `exclude` vaccine side effects due to developmental and reproductive toxicity of Covid vaccine, 44 pregnant rats-each injected with a full human BNT162b2 dose-were studied over a period of (only!) 42 days.3 One half of the rats were euthanized and necropsied after birth (21 days). The other half were allowed to give birth naturally, with the offspring observed for 21 more days, after which they were also euthanized. This is long before any developmental problems could have been observed as a vaccine side effect in the offspring and precludes any long-term safety or fertility studies and thus potential reproductive toxicity of Covid vaccine on the mothers or their offspring! The effects on fertility in this study were determined by dissection and examination of the ovaries of the rat mothers, which were fully grown at the time of "vaccination".

2.1 No evidence of developmental damage?

The authors state that there would be no vaccine harm in terms of maternal reproductive health and prenatal and postnatal development of the offspring - although the data they published may well show the opposite. The incidence of "pre-implantation loss" (failure of the fertilized egg to grow in the uterus) was 9.8% in the "vaccinated" rats and 4.1% in the control group, which is also confirmed by the experience of a German gynecologist ("vaccinated" are less likely to become pregnant).8 is confirmed. Although this difference was not statistically significant, it must be emphasized that only 42/44 (95%) rats became pregnant in the group of injected rats compared to the control group (43/44, 98%). A possible indication of vaccine side effects due to reproductive toxicity as a result of mRNA injection, can be clearly seen in this study.

2.2 Malformations as a vaccine side effect

As far as offspring are concerned, an increased incidence of supernumerary lumbar ribs (malformations) is observed in female fetuses treated with BNT162b2. The authors do not mention this fact - which follows from their own results. In a report of the Australian government on the active substance BNT162b2 from January 2021,9 it is recommended on p. 27 to delete the following sentence: "...showed no evidence of direct or indirect adverse effects on pregnancy, embryonic/fetal development and postnatal development." And replace as follows, "...showed an increased incidence of supernumerary lumbar ribs in fetuses...". Another indication of the potential reproductive toxicity of the Corona vaccine. In passing, the males used for mating, according to Pfizer (p. 29)10 were completely untreated.

"...nine out of 10 of the authors (had) serious conflicts of interest, having been employed by either Pfizer or BioNTech in addition to owning stock in the companies."

2.3 DART prerequisites not given

The authors of the study in question concluded that the prerequisites for a DART study were supposedly met.3 This is certainly not true for at least two reasons; (1) First, a complete reproductive cycle must be observed - as in humans - from first conception to reproductive viability in the next generation.1 (2) For another, nine out of ten of the authors have serious conflicts of interest, having been employed by either Pfizer or BioNTech and also owning stock in the companies.3 These circumstances alone should be sufficient to immediately stop all further clinical phases (global mass vaccination campaign) already conducted on the population at the time of publication (August 2021) - especially involving expectant mothers!

Experimental and, in particular, toxicological data show clear evidence of the hazard potential related to reproductive toxicity and potentially associated vaccine side effects of Covid vaccine. Possible causal relationships of reproductive toxic vaccine side effects of Covid-19 injections on women and fetuses are discussed below.

3. Nanoparticles - a known hazard to female fertility.

A review article on the distribution and toxicity of nanoparticles on the female reproductive system, comprehensively presents the distribution of nanoparticles in the body and the associated crossing of all biological barriers, as well as toxic effects on fertility.11 Harmful effects can be found at the cellular and organ level, as well as in the hormonal system, which is also true with respect to the male reproductive tract and is explained in detail in this article. The following figure provides an overview.

3.1 Lipid nanoparticles, a declared reproductive toxicant ingredient, potentially leading to sterilityhe Ingredient potentially leading to sterility

A special form of nanoparticles, so-called lipid nanoparticles (LNP), are also used for the transport of the mRNA. From this, the reproductive toxicity of the Corona vaccination and the associated vaccine side effect in the form of miscarriages and other pregnancy complications can be clearly deduced, which will be explained in detail below.

"...the strongest accumulation of LNPs and thus mRNA (was) observed 48 hours after injection and was largely in the liver and adrenal glands- closely followed by the ovaries..."

In one of the recently (spring 2022) declassified Pfizer documents, are studies on the bio-distribution (distribution) of BNT162b2 in rats.12 The data show a distribution of known toxic13, 14, 15 and highly inflammatory16 LNPs, which contain the mRNA, and accumulate in blood plasma and all organs. Of all 31 organs studied, the greatest accumulation of LNPs and thus mRNA was observed 48 hours after injection and was mostly in the liver (30.4 μg/g) and adrenal glands (14.9 μg/g) - closely followed by the ovaries with 12.3 μg/g. LNPs were also detected in the uterus - although at much lower concentrations (0.456 μg/g). The manufacturer Pfizer has been aware of these results since at least September 2020.12 The results were also confirmed, with only slight deviations, by a confidential Japanese government investigation, the results of which had already been available to the (informed) public since May 2021.17

3.2 LNP not approved for diagnostic or therapeutic purposes according to manufacturer

According to the official information provided by the US Centers of Disease Control and Prevention (CDC), the active ingredient mRNA-1273 (Moderna) contains a substance called SM-102 as one of the listed LNPs.14 The manufacturer, Cayman Chemical, makes the following statements about its use in its Safety Data Sheet:15"This product is intended for research use-not for diagnostic or therapeutic use in human or veterinary medicine." Further, SM-102 exhibits "reproductive effects" and is classified by the manufacturer as  "highly lammable in liquid and gaseous form " and "highly hazardous to health" and "Carcinogenic to humans".15 according to the International Agency for Research on Cancer's  (IARC) highest class 1A for carcinogens.18  Any doubters and 'fact-checkers' who share the opinion that the dangers relate only to the alcohol contained in the product should refer to the Substack article by Dr. Jessica Rose.19 These facts alone clearly prove the reproductive toxicity as well as the associated danger due to vaccine side effect of the mRNA vaccination!

3.3 Ovarian cancer due to accumulation of LNP in ovaries?

Due to the fact that carcinogenic LNPs15 especially also accumulate in the ovaries12, 17 it is reasonable to suspect that this is the cause of the significant increase (12% and 28%, respectively) in ovarian cancers as a possible vaccine side effect in 2021, which can be inferred from the Scottish Health Authority databases.20

"But what's a negligible amount in breast milk, for a tiny newborn with no immunity that just came into the world?"

3.4 Transfer into breast milk and to infants

A preliminary publication of data from the National Institutes of Health in the USA21 on measurements of LNP in breast milk gives the all-clear due to 'negligible' (statistically non-significant) amounts. But what is a negligible amount in breast milk for a tiny newborn with no immunity that has just come into the world? A look at the data reveals strikingly elevated levels as a result of the injection for at least 1/13 mothers studied. However, the sample is so small with 13 subjects that a serious interpretation is obviously difficult to make.

No significant differences were observed between samples collected at any of the postvaccination (PV) and prevaccination time points (paired and unpaired two-tailed t tests). Y-axes represent the time of sample collection in hours (h) or weeks (w) after vaccine 1 (PV 1) or after vaccine 2 (PV 2). Golan et al. (2022).21

However, against this background, the total of 61 suspected vaccine side effects in the 18th safety report of the German Paul Ehrlich Institute (PEI), which refer to infants whose mothers were vaccinated during the breastfeeding period, are striking.22 An exclusion of reproductive toxicity of the Corona vaccination in the offspring in this way, of course, was also never carried out.

The selective placental barrier normally separates the blood circulation of mother and fetus, so that the latter can be kept free from harmful substances. Based on the aforementioned study on breast milk21 and the fact that the LNPs undoubtedly also pass other selective barriers (e.g. blood-testis barrier and blood-brain barrier),12, 17 it can be assumed that the LNPs containing mRNA can also pass this barrier and thus endanger the fetus.

4. vaccination side effect "Infertility due to anti-syncytin-l antibodies?

In a petition addressed to the EMA, Dr. Wolfgang Wodarg and Dr. Mike Yeadon, former Chief Scientist and Vice President of Allergy and Respiratory Research at Pfizer, call for an immediate halt to the ongoing Covid 19 injections. Among other reasons, they point to the danger posed by the injections of stopping the development of the placenta - without which pregnancy is impossible - which would consequently lead to infertility.23 This well-founded concern is based on the gene 'syncytin-l', which is essential for the formation and development of the human placenta, encodes the information for the development of the placenta and is essential for the nutrition of the fetus in the womb.24, 25

"It is noteworthy that the authors repeatedly indicate that there was no increase in the binding activity of anti-syncytin-l antibodies as a result of the injection ... although their own data show the clear opposite."

Common sequences (homologies) exist in the amino acid sequence of syncytin-I and the Sars-CoV-2 spike protein.26 Antibodies produced by the injected mRNA could thus possibly also bind to syncytin-l and, as anti-syncytin-l antibodies, potentially result in vaccine side effects during placental development and fetal development.23

4.1 Study demonstrates anti-syncytin-l antibody activation as a vaccine side effect

Data from scientists in Singapore (preprint, peer review pending) support this concern.27 The binding activity of anti-syncytin-l antibodies was measured in blood serum before (day 0) as well as after (day 1-4; week 4-5 & 6-7) the injection. All post-injection measurement time points show a mean 4-7 fold increase in binding activity compared to day 0 measurement, with the greatest increase in values at day 1-4 post-injection. The lowest measured binding activity on day 1-4 is approximately in the range of the highest value measured prior to injection, with the highest value measured on day 1-4 exceeding the highest measurement on day 0 by approximately 2.5-fold.

The lower (negative) and upper (positive) dashed lines represent the arbitrary and not clinically validated threshold values. According to the authors, a significant increase of binding antibodies against the human syncytin-1 antigen (B) can only be assumed when the upper line is crossed. The dashed short line represents the mean value, the error bars the standard deviation. Comparing the distribution of the values of the different measurement times (days), a clear multiplication of the syncytin-1 antigen as a result of vaccination can be observed. Taken from Mattar et al. (2021).27

4.2 Authors embezzle essential results

It is remarkable that the authors repeatedly point out that there was no increase in the binding activity of anti-syncytin-l antibodies by the injection and they interpret the observed results as negative, although their own data show the clear opposite. The reason for this is that the study did not establish day 0 as the baseline rate as the 'control' measurement, but rather a standardized laboratory threshold. This was clearly above all measured values, which is why the measured differences between the measurement times were ignored as a reliable baseline rate. Why a control measurement was performed if this was then not used as a baseline rate for comparison is not comprehensible. According to the authors, no data are available on clinically meaningful thresholds for anti-syncytin-l antibodies, from which, however, it is not clear why the actually observed drastic differences before and after injection were completely ignored and unmentioned. The activation of anti-syncytin-l antibodies represents a possible as well as plausible causal mechanism for the significantly increased incidence of vaccine side effects in the form of miscarriages following mRNA injections, which are comprehensively explained and substantiated here.

It should be mentioned in passing that immunocontraceptives have already been developed and tested for many decades, as shown in our article "Population reduction through immune contraception?" can be taken. As early as 1974, antibodies against the protein specific for pregnancy and synthesized in the placenta were successfully used to β1-glycoprotein (SP1), successfully induced abortions.28

5. Vaccine side effect infertility due to spike protein, mRNA & gene manipulation.

In addition to the toxicity, which per se already results from the LNPs containing mRNA,13, 14,15, 29 it must be assumed that all affected tissue structures (incl. uterus, placenta and ovaries), in accordance with the intended mode of operation of the mRNA vaccination, also produce spike proteins independently through a process known as 'translation'30 - with all the associated dangers.31 The spike protein can damage the body in several ways, including cardiovascular complications by damaging endothelial cells (cells in blood vessels),31 autoimmune reactions due to binding of the spike proteins to the surfaces of organs,32 integration of the mRNA encoding the Sars-CoV-2 spike protein into DNA,31, 32, 33,34 as well as the release of destructive anti-spike antibodies.35

"For unexplained reasons, the percentage of intact mRNA in commercial batches is worryingly low at 55%-78%."

Reverse transcription of administered mRNA into DNA 6 h post-injection, was demonstrated in human liver cells.36 Although integration into the human genome was only possible for the mRNA of the Sars-CoV-2 spike protein34 and not as a result of mRNA injection were detected, it can be assumed that Covid vaccine mRNA also lead to genome integration. Possible genome integration is discussed in more detail in our article "Infertility and sperm quality after vaccination?"explained. In addition, according to a recently published study, adaptive immunity is suppressed by inhibition of DNA damage repair and represents a possible mechanism caused by spike proteins and injections based on them, which further underlines and clarifies the risk potential of a vaccine side effect of mRNA vaccinations.37

5.1 Transfer of spike protein & mRNA into breast milk and to infants.

A study published as early as 2021 38 (still in journal-preprint status without peer-review) was able to follow up with BNT162b2 injection twice, for 10 breastfeeding mothers a strong increase in specific Sars-CoV-2 antibodies was measured in 100% of the milk samples. Traces of inoculated mRNA were measured in 4/40 milk samples across all measurement time points. The latter is also confirmed by a more recent publication. In 7 of 11 breastfeeding mothers up to 48 hours after mRNA injection (Pfizer or Moderna) the presence of the `inoculated` mRNA was detected in breast milk.39 References to the transfer of LNP into breast milk have already been elaborated in Section 3.21 It can be assumed that spike proteins produced elsewhere in the body and circulating in the bloodstream also reach the ovaries, uterus and placenta and cause a possible vaccine side effect there. This assumption can be derived from evidence of Sars-CoV-2 viral RNA, which has been detected in the uterus, ovaries, and vagina of infected Covid-19 patients.40

5.2 Loss of ovarian function due to undeclared mRNA components?

Worrying are statements of an anonymous whistleblower, who according to his own statement is a development engineer at the `vaccine` manufacturer Moderna and already informed in December 2020 in an anonymous forum that only a part of the contained mRNA codes for the spike S protein.41 According to his information, the unknown mRNA material codes for mutated versions of two proteins called `CYP19A1` and `CDKN1B`, which cause premature loss of ovarian function (sterility) in the subsequent generation. At this point it must be made clear that neither the identity nor the information on the professional background of the whistleblower can be checked for accuracy in any way. However, the following substantive points can be verified and substantiated:

  • Both CYP19A1 and CDKN1B are known gene mutations associated with the occurrence of both complete and partial loss of ovarian function (primary ovarian failure and primary ovarian failure), according to a U.S. Food and Drug Administration study.42
  • The expression of the enzyme CYP19A1 triggered by Sars-CoV-2 in the lungs of men, is associated with worse covid-19 disease progression as well as reduced testosterone levels.43 (Reference our article on the effects on male fertility).
  • The British Medical Journal (BMJ) published information in March 2021 regarding inconsistencies in mRNA content between BioNTech-Pfizer clinical and commercial batches. For unexplained reasons, the percentage of intact mRNA in the commercial batches is worryingly low at 55%-78%. 44 According to the BMJ, the information comes from a cyberattack at the European Medicines Agency (EMA) and involves documents from the approval process and email histories of EMA regulators.

Whether there is corresponding mRNA material in Moderna's batches cannot be determined at the present time, but it seems to be within the realm of possibility. If this turns out to be true, the whistleblower's statements - as can be seen from the comments - are more than justified.

Causative mechanisms for vaccine injury as a result of the mRNA vaccination can be cited extensively as discussed in this article. For further information on contraceptive vaccines and pregnancy complications following Covid 19 injections, please refer to the articles "Declining population through birth control shots [`vaccinations`]! Fact or myth?" and "Pregnancy Complications and Birth Decline after Covid Vaccination".
