Pregnancy is considered a high-risk state when it comes to severe Covid.
If you're pregnant and fully vaccinated, having received two doses of the Pfizer-BioNTech vaccine at least 6 months ago, you're now eligible for a third dose of the Covid vaccine.
Pregnancy is considered a high-risk state and is on the Centers for Disease Control and Prevention's (CDC) list of health conditions that increase the risk of severe Covid.
Even though the absolute risk of disease is low, if you're pregnant and contract Covid, you are more than twice as likely to end up in intensive care or require time on a ventilator than a non-pregnant person who has symptoms of the disease.
Your immune system changes in pregnancy
Because the immune system is naturally weaker during pregnancy, getting sick means your body has fewer defenses to fight off infection—and a virus like SARS-CoV-2 can more easily take hold. Vaccination against Covid is the most effective way to prevent severe disease. And though the vaccines work well even against the highly contagious Delta variant, experts are starting to see slightly waning protection after 6 months from the last dose.
After a worryingly high number of pregnant women died in August due to Covid (22), the CDC is once again strongly urging pregnant women to get vaccinated if they haven't yet.
A booster shot offers even further protection, especially if it's been at least 6 months since your second shot, or you have another underlying condition or work in a high-risk job, like healthcare or teaching.
"There is a known increased risk of complications from COVID-19 in pregnant patients with underlying health conditions (e.g. diabetes, obesity, increasing age, and cardiovascular disease)," says the CDC.
Data indicates that 97% of pregnant people who were infected with Covid when they were hospitalized were not vaccinated—and as of mid-September, only 31% of pregnant people in the U.S. were vaccinated.
A booster shot now could offer protection to your infant once born
"Pregnancy can be both a special time and also a stressful time, and pregnancy during a pandemic is an added concern for family," said Dr. Rochelle Walensky, director of the CDC. Talk to your doctor about the benefits of vaccination and any potential risks you're worried about.
Getting vaccinated in pregnancy can offer significant benefits to your baby:
- A growing body of research shows that antibodies from the vaccine are passed to the fetus when a mother gets vaccinated in pregnancy.
- Because no vaccines are currently available for young infants (under 6 months of age)—and likely won't be—getting vaccinated yourself is the best way to protect your newborn.
- Even after pregnancy, studies have shown that vaccine antibodies can pass through your breast milk after vaccination.
How to get a Covid booster shot
Your first step should be to talk to your obstetric care provider. Then:
- Call your local pharmacy to see if scheduling an appointment is necessary.
- Be sure to bring your vaccine card.
- You won't need to provide proof of your pregnancy or underlying medical condition.
Should you mix brands of Covid vaccine shots?
At this time, mixing vaccines (i.e., getting a Moderna shot after you've gotten two Pfizer shots, or getting a Pfizer shot after you've gotten two Moderna shots) is not recommended. We just don't have enough data yet on the effects of mixing brands of vaccines. Be sure to check in with your doctor or midwife for the latest updates.
