Claim that COVID-19 Vaccine Causes Infertility is Unfounded

covid-19 vaccine and infertility in women

As a fertility company, RMA keeps a close eye on developments in the news related to reproductive endocrinology, pregnancy, and birth.

Recently, there have been news reports about a claim that Pfizer’s coronavirus vaccine, which received Food and Drug Administration (FDA) emergency use authorization Friday (11/12/2020) and will be administered to frontline workers and nursing home residents starting Monday, could cause infertility in women.

The claim, made by a British former Pfizer employee and a German doctor – both of whom have downplayed the COVID-19 pandemic – is based on the idea that the vaccine could cause the immune system to attack a protein that has a critical role in the development of the placenta during pregnancy.

However, experts say this claim is flat out inaccurate; there is no data showing a link between the Pfizer vaccine and infertility. In fact, as part of its authorization last week, the FDA left open the door for pregnant and breastfeeding women to receive the vaccine as part of the initial rollout to health care workers.

According to The New York Times , the Pfizer vaccine does not contain placental proteins or genetic material that instructs the manufacture of placental proteins. Plus, an immunologist told the news outlet, the coronavirus protein the vaccine instructs your body to make, called a spike, which tells the body to fight the virus, has “almost nothing” in common with placental proteins.

Moreover, the expert said, humans have evolved to suppress immune reactions that harm their own tissue.

In summary, there is no data to suggest the coronavirus vaccine causes infertility or fertility-related issues. There is evidence, however, that being infected with the coronavirus causes serious deleterious effects on the health of young, previously healthy individuals.

At present, there are two types of vaccines that may be accessible to the public. The first type of vaccine (Pfizer’s BNT162b2, Moderna’s mRNA-1273) uses mRNA-based technology and does not contain a virus. This type of vaccine is believed to be safe, although these are the first vaccines of this kind.

The second type of vaccine uses viral vector technology (AstraZeneca’s AZD1222). The viral vector technology has been studied in Ebola vaccine trials and found to be safe in pregnancy.

The Society for Maternal-Fetal Medicine (SMFM) has concluded it is advisable to administer the vaccines to pregnant women who are at high risk to contract the virus.

RMA will continue monitoring the news related to fertility and COVID vaccines and will communicate important insights to our fertility community.

Meanwhile, we hope you stay safe, wear a mask, socially distance, and limit public gatherings, especially if you are pregnant or trying to conceive.

Dr. Jason Franasiak was inspired to go into reproductive medicine by his parent’s dedication to women’s healthcare. His father was an OB/GYN and his mother was a labor and delivery nurse. “This notion inspired me as a child and continues to do so today,” he says. “Helping people build happy and healthy families is so rewarding.”
