COVID-19 Vaccine Safety Analysis Finds Signals for Miscarriage, Menstrual Irregularities

Researchers have identified 14 safety signals for the COVID-19 vaccines used in the United States, including menstrual abnormality, miscarriage, and fetal cardiac arrest, according to a study released on Sept. 28.

Dr. James Thorp, with Maternal Fetal Medicine in Florida, and other researchers performed a type of analysis called proportional reporting ratio on reports submitted to the Vaccine Adverse Event Reporting System (VAERS). VAERS accepts reports of adverse events following vaccination.

Comparing the rates of events following COVID-19 vaccination to those reported following influenza vaccination, the researchers found a significant increase in 14 conditions, including fetal malformation, fetal cardiac arrest, and stillbirth.

“Pregnancy and menstrual abnormalities are significantly more frequent following COVID-19 vaccinations than that of Influenza vaccinations. A worldwide moratorium on the use of COVID-19 vaccines in pregnancy is advised until randomized prospective trials document safety in pregnancy and long-term follow-up in offspring,” researchers said in the study, which was published online ahead of peer review.

“There’s enough of a safety signal in our research in looking at VAERS that really we should take a pause from the vaccines until they are studied more in depth,” Claire Rogers, with the Truth for Health Foundation and one of the authors, told The Epoch Times.

The U.S. Centers for Disease Control and Prevention (CDC) recommends COVID-19 vaccines for virtually all people aged 6 and up, including pregnant women. Some groups and doctors support the recommendations, while others have called for a pause on some or all of the vaccines due in part to safety concerns.

PRRs

Proportional reporting ratio analysis (PRRs) involves comparing the rates of adverse events following one type of vaccination with the rates of adverse events following a different type or all other types. The researchers in the new study analyzed the relative rates by time, by dose, and per person.

Adverse events that were identified as having an increase with COVID-19 vaccination of two-fold or more compared to flu vaccination are: menstrual abnormality, miscarriage, fetal chromosomal abnormalities, fetal malformation, fetal cystic hygroma, fetal cardiac disorders, fetal arrhythmia, fetal cardiac arrest, fetal vascular mal-perfusion, fetal growth abnormalities, fetal abnormal surveillance, fetal placental thrombosis, stillbirth, and low amniotic fluid.

An increase of two-fold or more constitutes a safety signal, according to the CDC. A safety signal is an identification of a possible connection between a vaccine or vaccines and an adverse event.

The agency has said it would perform PRRs on VAERS reports by comparing reports following a COVID-19 vaccine to reports following all other vaccines. But the CDC has refused to provide the results to the public or The Epoch Times as of yet.

The agency earlier this year said it did not perform and would not perform the analysis on the reports, contradicting previous statements. A top agency official, Dr. John Su, then said that the CDC started performing them in February 2021. The CDC later reversed itself again, saying it didn’t start until 2022.

CDC Director Dr. Rochelle Walensky said in a recent letter that the PRRs the CDC did perform identified “no additional unexpected safety signals.” The expected signals were four adverse events that have been linked to COVID-19 vaccines, a CDC spokesperson told The Epoch Times via email. They are severe allergic shock, blood clotting, Guillain-Barre Syndrome, and heart inflammation.

Another type of analysis on VAERS data, Empirical Bayesian data mining, was done by U.S. Food and Drug Administration researchers. They have said they didn’t identify any signals for the vaccines authorized in the United States, but have also refused to release the results.
