Is the COVID-19 vaccine safe for pregnant or breastfeeding mothers?
Yes! The Centers for Disease Control (CDC), American College of Obstetricians and Gynecologists (ACOG) and the Society for Maternal-Fetal Medicine (SMFM) all agree that the COVID-19 vaccination should be offered to pregnant and breastfeeding women . While initial clinical trials did not include pregnant women, studies have now been conducted to confirm the vaccine is safe for pregnant and breastfeeding women, including evidence showing no increased risk for miscarriage . The CDC has continued its commitment to widespread monitoring using multiple surveillance programs to ensure safety . One of these systems, known as v-safe, reports that 158,000+ pregnant women have already been vaccinated, and 5,100+ women have become pregnant after vaccination .
Should someone wait to get a COVID-19 vaccine if they want to get pregnant?
No! COVID-19 vaccination does not affect fertility, including in-vitro fertilization (IVF) [5,6]. Vaccination also dramatically decreases the chance of infection and reduces risk of severe illness, ultimately protecting both mothers and their babies. On the other hand, getting COVID-19 can be a significant risk to both pregnant and non-pregnant women’s health. Pregnant women are at increased risk for health complications during and after pregnancy due to COVID-19 infection [6,7].
Increased risk for COVID-19 complications for pregnant people:
- Death: 17.0x
- Respiratory distress: 34.4x
- Sepsis: 13.6x
- Shock: 5.1x
- Admission to ICU: 3.6x
- Kidney failure: 3.5x
- Blood clotting issues: 2.7x
- Adverse cardiac event: 2.2x
- Preterm Labor/Delivery: 1.2x
But I thought pregnant women weren’t supposed to get vaccines…
Most vaccines are not recommended for pregnant women, outside of the flu, Tdap and COVID-19 vaccine. This is because many vaccines use "live virus" technology which is potentially dangerous to a baby. mRNA vaccines used in the Moderna and Pfizer COVID-19 vaccines are not live virus vaccines and are non-infectious, meaning they cannot give you COVID-19. Additionally, these vaccines do not affect or interact with your own DNA in any way. While COVID-19 vaccines are relatively new, the technology behind them has been around for many years and is held to the same rigorous safety and effectiveness standards as all other types of vaccines. With COVID-19 posing larger risks for pregnant women and unborn children, vaccination is a important step in protecting the health of both mother and baby.
Will my vaccination help protect my baby from COVID-19?
Yes! Infants depend on their mothers for immunity. The vaccine itself stays near the muscle of the injection site and surrounding lymph nodes, but the antibodies it creates circulate the bloodstream . These antibodies then cross the placenta during the last 3 months of pregnancy via the bloodstream or enter the breast and are passed on to the baby through breast milk . Studies show this to be true for COVID-19 vaccine antibodies as well .
