COVID-19 Vaccinations do not Increase Miscarriage Rate, Cause or Interfere with Fertility

Woman reading a positive pregnancy test - get vaccinated


In mid-July, the weekly average for COVID 19 cases increased by almost 70%. Reliable news media is calling the latest increased a “pandemic of the unvaccinated.”  After the new vaccines were released and widely available to the general public hospitalizations and death began to fall abruptly. As of the writing of this article, hospitalizations are increasing due to the highly contagious delta variant. This is particularly true of the states and regions where vaccination rates are low. Most (97%) of patients needing to be hospitalized are unvaccinated.

If you are undergoing fertility treatment, please discuss getting the vaccination with your reproductive endocrinologist, The ASRM reports that CDC current data suggest only 16% of pregnant women receive less than one dose of COVID-19 vaccine during their pregnancy. This is quite concerning because there is a known increased risk of unfavorable outcomes for women infected with the virus during their pregnancy.

INCIID aligns with the ASRM encouraging vaccination for all fertility patients during evaluation and treatment for infertility. Vaccinating pre-conception and early during pregnancy is the best way to reduce complications.  Please talk to your physician about getting the vaccination for you, your family, and for your baby.

 Please be aware that according to the ASRM, none of the currently available COVID-19 vaccines reach or cross the placenta. The mRNA vaccine is given in the muscle (upper arm). There it remains in the muscle cell cytoplasm until it is destroyed in just a few days. To learn how these mRNA vaccines work, watch the video.


It is important to also note that the antibodies (that protect you from a virus) do cross the placenta. This means that not only are you getting protection but your baby benefits from these antibodies as well. According to the ASRM, these vaccines do NOT produce antibodies against the placenta, and vaccination during pregnancy does not increase the risk of miscarriage OR impact male or female fertility treatment outcomes.
