Researchers Find No Associations Between Pfizer, Moderna Vaccines And Adverse Effects On Stimulation, Early Pregnancy Outcomes With IVF
Healio (1/25, Gawel) reports, “Researchers found no associations between the Pfizer-BioNTech and Moderna mRNA vaccines and adverse effects on stimulation or early pregnancy outcomes with IVF, according to a study published in Obstetrics & Gynecology.” Devora A. Aharon, MD, the author of the study, said, “This study found no significant differences in response to ovarian stimulation, egg quality, embryo development or pregnancy outcomes between the vaccinated compared to unvaccinated patient.” Healthline (1/25) and Reuters (1/26) also report.
COVID-19 Vaccination Not Tied To Impaired Fertility In Women, Men, Study Suggests
CNN (1/22, Howard) reports a study published in the American Journal of Epidemiology “adds to growing evidence that there is no connection between Covid-19 vaccinations and a reduced chance of conceiving a baby.” Instead, “couples in the study had slightly lower chances of conception if the male partner had been infected with the coronavirus within 60 days – which offers even more reason to get vaccinated against Covid-19, since the illness could affect male fertility in the short term, according to the study.”
Bloomberg Law (1/20, Baumann, Subscription Publication) reports, “Data from tens of thousands of individuals indicate the vaccines are safe for pregnancy and can even build and pass antibodies along to the baby, according to the American College of Obstetricians and Gynecologists.” ACOG and the CDC “have both recommended Covid-19 shots for anyone who’s pregnant or trying to become pregnant.” MedPage Today (1/20, D’Ambrosio) also reports on the study.
NCFMC recommends vaccination for all of our patients, barring any medical issues that would otherwise exclude them from vaccination. Covid vaccination is safe for pregnant people and patients undergoing fertility treatment; pregnancy and/or infertility are not medical exemptions to vaccination. We are unable to provide letters for medical exemption from vaccination to our patients. If a patient has a medical issue that prohibits vaccination, they will need to speak with the physician managing that medical issue for an exemption letter.
American Society of Reproductive Medicine Covid-19 Update:
- None of the currently available COVID-19 vaccines reach or cross the placenta. The intramuscularly administered vaccine mRNA remains in the deltoid muscle cell cytoplasm for just a few days before it is destroyed. However, protective antibodies to COVID19 have been shown to cross the placenta and confer protection to the baby after delivery.
- COVID19 vaccination does not induce antibodies against the placenta.
- Existing data suggest COVID19 vaccination during pregnancy does not increase risk of miscarriage.
- COVID19 vaccination does not impact male or female fertility or fertility treatment outcomes.
