- No impact on fertility was observed
- Long term side-effects were highly unlikely
- Pregnant women likely to transfer antibodies to unborn child
A new study adds to the growing body of data that COVID-19 vaccinations are safe for both pregnant women and men trying to conceive.
The study, which included almost 2,000 couples from the United States and Canada, discovered “no detrimental connection” between getting vaccinated against COVID-19 and fertility in both men and women.
Men who contract COVID-19, on the other hand, may experience a transient decrease in fertility. Couples with a male partner who tested positive for COVID-19 within 60 days of their spouse’s menstrual cycle were 18% less likely to conceive during that cycle, according to the study, which was published in the American Journal of Epidemiology on Jan. 20.
Dr. Diana Bianchi, director of the Eunice Kennedy Shriver National Institute of Child Health and Human Development at the National Institutes of Health, which financed the study, stated in a statement:
“The findings provide reassurance that vaccination for couples seeking pregnancy does not appear to impair fertility.”
“They also provide information for physicians who counsel patients hoping to conceive.”
The idea that COVID-19 vaccinations may harm fertility was widely disseminated on social media.
More and more study has revealed that vaccines do not only not effect fertility, but also do not affect pregnancy.
The Centers for Disease Control and Prevention (CDC) released a research on January 4 that found no higher risk of preterm or low-weight delivery among babies born to pregnant women who received a COVID-19 vaccination shot compared to babies born to uninfected pregnant women.
The researchers at Yale University examined the health records of over 40,000 pregnant women and found no safety concerns with getting vaccinated while pregnant, regardless of which trimester a woman was in when vaccinated or how many vaccine doses she received during her pregnancy.
The majority of the women in the study were vaccinated in the second or third trimester, and the study did not include booster doses.
The CDC stated in a September health warning recommending pregnant women to get vaccinated that there is no increased risk of miscarriage associated with taking a COVID-19 vaccine.
“Miscarriage rates after receiving a COVID-19 vaccine were similar to the expected rate of miscarriage,” the CDC said at the time.
“Additionally, previous findings from three safety monitoring systems did not find any safety concerns for pregnant people who were vaccinated late in pregnancy or for their babies,” it further said.
Furthermore, according to two studies published this summer, Pfizer and Moderna’s COVID-19 vaccinations appear to be safe and effective for pregnant women, and they are also likely to protect infants born to a vaccinated individual.
The CDC strengthened its recommendation for COVID-19 vaccination during pregnancy in August, citing new evidence of vaccine safety.
The American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM), the country’s two largest health organizations focused on the treatment of pregnant people, both announced new guidelines urging all pregnant women to get vaccinated against COVID-19.
The World Health Organization (WHO) also claims that pregnant women can be immunized against COVID-19.
“Limited data are currently available to assess the safety of COVID-19 vaccines in pregnancy. However, based on what we know about the kinds of vaccines being used, there is no specific reason for concern,” the WHO says on its website.
“None of the COVID-19 vaccines authorized to date use live viruses, which are more likely to pose risks during pregnancy.”
Both the Pfizer and Moderna vaccines employ mRNA technology, which does not enter the nucleus of the cells and does not alter human DNA; instead, it sends a genetic instruction manual to cells, prompting them to produce proteins that resemble virus components as a way for the body to learn and develop defenses against future infection.
They are the first mRNA vaccines that, because they do not include a live virus, are potentially safe to use during pregnancy.
The Johnson & Johnson vaccine employs an inactivated adenovirus vector, Ad26, which is incapable of replication. The Ad26 vector carries a fragment of DNA containing instructions for producing the SARS-CoV-2 spike protein, which causes an immunological response.
This same sort of vaccination has been approved for Ebola and has been widely researched for other infections, as well as how it affects pregnant or breastfeeding women.
After evaluating more than 200 pages of data provided by the firm and the US, the CDC ruled that pregnant women can get the Johnson & Johnson one-shot vaccine. FDA (Food and Drug Administration) (FDA).
Although pregnant women are advised not to get live-attenuated virus vaccines, such as the one for measles, mumps, and rubella, because they can pose a theoretical risk of infection to the fetus, vaccine experts interviewed by ABC News said the Johnson & Johnson vaccine does not contain live virus and should be safe.
The COVID-19 virus has also been shown to be more harmful for pregnant women, particularly if they have not been vaccinated.
According to the CDC, COVID-19 doubles the risk of critical care hospitalization and increases the chance of death by 70% in pregnant women.
A study performed by Scottish researchers and published this month in Nature Medicine discovered that unvaccinated pregnant women who developed COVID-19 were not only at risk of more severe sickness, but were also more likely to experience pregnancy loss or preterm birth than other women. – ABC News
