The vaccine maker is launching a clinical trial to assess safety of its vaccine in pregnant women, despite 133,000 pregnant women having already received a COVID vaccine prior to trials.
Moderna will begin studying its COVID vaccine in pregnant women, according to a posting on ClinicalTrials.gov. The observational study, expected to begin July 22, will enroll about 1,000 females over age 18 who will be studied over a 21-month period.
Women who received a Moderna vaccine during the 28 days prior to their last menstrual period, or at any time during pregnancy, are eligible.
The brief summary of the trial states the main goal is “to evaluate the outcomes of pregnancy in females exposed to the Moderna COVID-19 vaccine (mRNA-1273) during pregnancy.”
The study will measure the number of participants who have infants with suspected major and minor congenital malformations, the number of participants with any pregnancy complications, the number of participants with any pregnancy outcomes and the number of participants with infant outcomes, Fox Business reported.
Currently, the Centers for Disease Control and Prevention (CDC) says pregnant women can get a COVID vaccine. But the CDC also acknowledges there is limited data available about the safety of COVID vaccines for people who are pregnant.
“No evidence exists of risk to the fetus from vaccinating pregnant people with non-replicating vaccines in general. However, the potential risks of COVID-19 vaccines to the pregnant person and the fetus are unknown, because these vaccines have not been extensively studied in pregnant people.”
According to the CDC’s website, as of June 29, data collected from the CDC and U.S. Food and Drug Administration’s (FDA) safety monitoring systems had not identified “any safety concerns for pregnant people who were vaccinated or their babies,” but the agencies stressed findings are preliminary.
“We have no long-term studies showing it’s safe. We made this mistake with diethylstilbestrol — a synthetic estrogen thought to be safe during pregnancy that was later found to cause aggressive (and sometimes lethal) cancer in the genitals of young teenagers whose moms had been prescribed it.”
Margulis believes it is irresponsible, and even unethical, to assert that we know the Moderna vaccine is safe for pregnancy.
“It’s imperative to use the precautionary principle when it comes to this highly experimental technology. The burden of proof must be on the intervention. We have no evidence that this is safe. But ample evidence shows that it is dangerous to expose pregnant women and unborn babies to drugs and interventions that can disrupt immunity.”
The most recent data from the Vaccine Adverse Events Reporting System (VAERS) — one of the safety monitoring systems co-managed by the FDA and CDC — has received 2,678 reports of adverse events related to COVID vaccines in pregnant women, including 994 reports of miscarriage or premature birth between Dec. 14, 2020 and July 2, 2021.
Data assessing safety of COVID vaccines in pregnant women is lacking
According to a March 1 safety update by the CDC’s vaccine safety panel on the COVID vaccine and pregnancy, post-authorization safety monitoring and research are the primary ways the CDC obtains safety data on COVID vaccination during pregnancy.
In other words, the vaccine is given to pregnant women before studies determine whether the vaccine is safe for that population. The CDC’s website states that 133,466 pregnant women have already received a COVID vaccine as of July 12.
“It seems bass-ackwards to release the vaccine to pregnant women before doing a clinical trial or proper animal studies,” said Lyn Redwood, RN, MSN and president emerita of Children’s Health Defense.
“Does the vaccine lipid nanoparticle cross through the placenta? If so, what is the effect on the offspring with regard to morbidity or mortality? These are questions we need to be asking. Pregnancy used to be a time where we were to protect the mother and baby from any potential harms, especially during the first trimester.”
The authors of the study stated they found no increased risks during pregnancy, or birth complications or identifiable risks to the fetus among those who received the vaccine.
Shortly after, the CDC updated its official recommendations that pregnant women receive a COVID vaccine based on the study’s data compiled over the course of two months.
CDC Director Rochelle Walensky highlighted the findings at an April 23 briefing where she stated the “CDC recommends that pregnant people receive the COVID-19 vaccine.”
According to Dr. Brian Hooker, Ph.D., P.E., Children’s Health Defense chief scientific officer and professor of biology at Simpson University, the results regarding pregnancy loss were highly skewed.
Hooker told The Defender:
“The majority of the denominator received their vaccine in the third trimester where pregnancy loss would be much less. Most of the pregnancy losses were in the first trimester and there are no data on the outcomes of the other women who received their vaccine in the first trimester (i.e., whether they carried to term), or data on the temporal relationship between receipt of the vaccine and miscarriage which is suspect.
“There is also no data regarding any incidence of clotting disorders reported or any type of blood malady that may occur (e.g., spotting or bleeding during pregnancy), and very limited treatment of neonatal outcomes (no APGAR score, etc.) due to the very limited duration of the study.
“This is typical ‘nothing to see here’ CDC propaganda and the paper is essentially meaningless regarding pregnancy outcomes. In order to adequately assess these outcomes, pregnancies need to be followed to term.”
Although Moderna’s clinical trial is expected to begin July 22, Pfizer and J&J already are conducting clinical trials testing the safety and efficacy of their vaccine in pregnant women.
