Peer-Review of CDC Study Concludes Pregnant Women Should NOT be Vaccinated

A pair of researchers conducted further analysis of a CDC study used internationally to promote vaccination among pregnant and breastfeeding women. They found that spontaneous miscarriage occurred in 81.9% to 92% of pregnancies when the mother received the COVID vaccine within the first 13 weeks of pregnancy.

They are appealing to all nations to halt the vaccination of pregnant and nursing women until further data is collected.

The CDC study released in June (also called the Shimabukuro et al. study) determined that the vaccine was safe for pregnant women, even though their data was inconclusive — they hadn’t allowed enough time to lapse to reveal the accurate data. All the while, they’d been recommending the vaccine to pregnant women, falsely touting its safety.

A Belgian researcher, Hong Sun, pointed out this original problem, resulting in the CDC admitting that they didn’t have sufficient data to accurately calculate the risk for miscarriage. They issued the correction on October 14, 

“No denominator was available to calculate a risk estimate for spontaneous abortions, because at the time of this report, follow-up through 20 weeks was not yet available.”

Senior lecturer in the University of Auckland’s Section of Epidemiology and Biostatistics Dr. Simon Thornley and Dr. Aleisha Brock, also from New Zealand, are the researchers behind this challenge of the report. They are accusing the study of providing a false sense of reassurance using unreliable and questionable data. 

“We question the conclusions of the Shimabukuro et al. study to support the use of the mRNA vaccine in early pregnancy, which has now been hastily incorporated into many international guidelines for vaccine use, including in New Zealand.”

In the original CDC report, information was taken from the CDC-operated V-Safe registry and analyzed. Live births resulted in 712 of the 827 pregnancies recorded. Nearly all of the women were vaccinated in the third trimester. What the CDC didn’t say was that of the remaining 115 pregnancies, 104 ended in miscarriage, with most of the mothers vaccinated before 13 weeks gestation.

The researchers found the spontaneous miscarriage rate was actually 7-8 times greater than the original report indicated, far exceeding the standard rate of miscarriage which is approximately 10-25% of all pregnancies.

Even the label on the Pfizer vaccine acknowledges that there is insufficient data regarding the vaccine-associated risk for pregnant women.

Though Sun challenged the original findings, he doesn’t necessarily support Thornley and Brock’s reanalysis.

“While I also suggest removing the 700 cases from the dominator, I also consider such an equation is no longer valid, in other words, it is not possible to calculate an accurate rate of spontaneous abortion rate with the given data, and this view is acknowledged by CDC. In [the CDC’s] follow-up study, a more reasonable rate is calculated and I consider it is a fair estimation.”

Thornley is still wary of the data, challenging the selection pool of participants. He doesn’t feel the data provides a broad enough scope to be deemed conclusive.

He told the Epoch Times, “There are at least some questions related to the selection of participants which are an issue for case-control studies, compared to a cohort analysis such as that found in the CDC data. The data which addresses this issue of safety, particularly concerning exposure to mRNA vaccines early in pregnancy, is sparse, from published evidence, and I would question anyone who believes it is in any way conclusive.”

Citing extremely low rates of fatality or severe outcomes from a COVID infection, he recommends that younger people, including those who are pregnant, forgo vaccination. “We caution against the use of the vaccine, given the substantial uncertainty that exists.”
