Vaxxed women are overall only 2/3 as likely to give birth. It's not just miscarriage rate, it's overall live births.

Again: What are exact causes?

Is it possible that Czech women who bought covid-vaxx hype or obeyed mandates, are simply more inclined to abortions? birth control? abstinence (doubtful)? ill health? disrupted cycles? infertile male partners?

But....wow. Major health alarm bell, needs explanation.......... that is, it needs study & headlines.

Observed-to-Expected Fetal Losses Following mRNA COVID-19 Vaccination in Early Pregnancy

Analysis of 226,395 singleton pregnancies in Israel from 2016 to 2022 indicates that COVID-19 vaccination with dose 1 during weeks 8-13 was associated with higher-than-expected observed number of fetal losses of approximately 13 versus 9 expected for every 100 exposed pregnancies

Miscarriage rate goes from 9% to 13%, rate increase around 45%.

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

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....

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.

Clearly, something is wrong.

There -could be some- "male contribution" ie. some chance of vaxx-matched partners & vaxxed-male sperm are different? More study is needed.

Also........... In spirit of "correlation isn't always causation (altho causation is always correlation)".........There could be something else -coincidental- to massive spread of covid vaxx only in 2021.....something -not- coincidental to spread of covid virus in 2020 & -not- coincidental to being unvaxxed.......... ........... Dirt on injection needles, or something.

Again, answer is: More study. Look into these things moar!

As I learn more about these studies: Post title is too mild.

What covid mRNA vaxx do, is make women bleed more.

Both Pfizer & Moderna do it. In the studies, menstrual women report heavier periods. Non-menstrual women (whether from hormones/pill or menopause) report resumption of periods.

If nothing else, it confirms - yet again - that vaxx escape injection site & distribute all over body, something they were promised originally to NOT do.
