Vaccinations during pregnancy are important and common. If you are pregnant or breastfeeding, you are likely familiar with vaccines that are typically recommended during pregnancy to prevent influenza (flu shot) and pertussis (Tdap vaccine).
Now you may be deciding if you should get the COVID-19 vaccine. This is a personal choice that you should make after talking with your doctor, who is your first point of contact to help you make an informed decision.
What do we know about the COVID-19 vaccine and pregnancy? The two mRNA COVID-19 vaccines, Pfizer BioNTech and Moderna, consist of messenger RNA and use the body’s own cells to generate the coronavirus spike protein, which stimulates immune cells to create antibodies against COVID-19. The third single-dose Janssen (J&J) vaccine, a vector vaccine, uses a harmless adenovirus (a type of virus that causes the common cold) to instruct the body’s cells to make the coronavirus spike protein, training the body's immune system to protect against COVID-19.
While mRNA vaccines are distinct from influenza and Tdap vaccines currently used during pregnancy, mRNA technology has been in development for the last decade.
The COVID-19 vaccines can’t give you COVID-19, as they do not contain the live virus that causes the coronavirus. Also, the mRNA does not enter the cell’s nucleus and does not alter human DNA, so the mRNA vaccines cannot cause any genetic changes, and your body’s cells break down the mRNA quickly.
While the current COVID-19 mRNA vaccines haven’t been studied in pregnant or lactating women, based on how mRNA vaccines work, experts believe they are unlikely to pose a specific risk for people who are pregnant, according to the Centers for Disease Control and Prevention (CDC). Likewise, mRNA vaccines are not thought to be a risk to the breastfeeding infant.
Similarly, experts believe that non-replicating viral vector COVID-19 vaccines are unlikely to pose a risk to the pregnant person or fetus. However, all women younger than age 50 (regardless of whether they are pregnant or recently pregnant) should be aware of the rare risk of thrombocytopenia syndrome (TTS) after receipt of the Janssen (J&J) COVID-19 vaccine.
While safety data on the use of the current COVID-19 vaccines in pregnancy are not currently available, there are also no data to indicate that the vaccines should be contraindicated (not used), and the safety for pregnant people is expected to be similar to non-pregnant people.
While there are still many unknowns, we do know that:
Pregnant and breastfeeding women need to weigh the potential benefits of vaccination (including preventing COVID-19 illness) against the potential risks regarding vaccination. Ask yourself, what is the risk of virus exposure and not getting vaccinated?
Guidance from the American College of Obstetricians and Gynecologists, Society for Maternal-Fetal Medicine and CDC, advocate for making COVID-19 vaccines available to pregnant and lactating women in consultation with their doctor.
