The benefits of COVID-19 vaccination appear to greatly exceed the theoretical risks, so our professional societies are recommending vaccination. Women of childbearing age are over-represented, compared to other fields, in the health care
industry. A high percentage of pregnancies are unplanned, so getting the vaccination will reduce your risk of getting COVID-19 and suffering severe complications if you do become pregnant.
Regarding vaccine safety, the Pfizer/BioNTECH and Moderna vaccines use mRNA, which makes a protein fragment that induces immunity in the vaccinated individual. So, the risk to the fetus and pregnancy is thought to be low, compared to using
an intact, replicating virus for the vaccination.
There is no evidence regarding the effect of vaccine on reproductive health. Other vaccinations against respiratory viral infections, such as influenza, do not suggest a negative effect on reproductive health from vaccination.
There was an initial concern that getting COVID-19 increases the risk of miscarriage, however, subsequent evidence does not appear to support this.
