Reliable sources on this subject include the following:
In general, pregnant people experience immune system and physiological changes that make them more susceptible to viral respiratory infections. Pregnant patients are at risk for more severe illness from a COVID-19 infection.
Patients who are pregnant or trying to conceive should follow the same precautions as people who are not pregnant:
Throughout the pandemic, UCSF has offered safe ways for our patients to access in-person support during the birthing process. Please visit the UCSF Health visitation page for up-to-date information about our visitor policies.
Since the onset of the pandemic, we have amassed a growing body of data on adverse pregnancy outcomes and COVID-19. Early pregnancy loss due to COVID-19 infection has not been observed (unlike with other related coronaviruses, such as SARS and MERS). There's also no evidence that COVID-19 causes birth defects, and there's no data suggesting that the virus routinely crosses the placenta and harms the newborn.
There is evidence, however, that pregnant patients with COVID-19 are more likely to progress to severe illness. They're more likely to be hospitalized, intubated and admitted to the intensive care unit than patients who aren't pregnant. We also know that COVID-19 infection during pregnancy can increase the risk of preterm birth and stillbirth.
Antiviral treatments are available to reduce the risk of severe COVID-19. Paxlovid (nirmatrelvir/ritonavir) is an oral antiviral medication that is recommended for patients at higher risk of developing more severe disease, including pregnant patients. The treatment must be started within 5-7 days of symptom onset to be effective. Contact your health care provider promptly after diagnosis. The CDC website also has resources on obtaining treatment.
There have been reported cases of COVID-19 transmission between parent and fetus during pregnancy, but this is very rare. More commonly, a person with an active COVID-19 infection during delivery can pass the virus to the infant during close contact after birth. The COVID-19 virus has not been detected in breast milk and breastfeeding should continue if possible, while taking hygiene precautions.
You can get additional information on breastfeeding and COVID-19 from the CDC.
All leading public and professional health organizations strongly recommend vaccination if you are pregnant or planning to be pregnant. Pregnancy increases the risk of severe complications from COVID-19, and the protection conferred by the vaccine helps to keep parent and baby healthy. Multiple studies from different countries have shown that the COVID-19 vaccine has no adverse effect on fertility, miscarriage or other pregnancy outcomes. The COVID-19 vaccine may cause mild menstrual irregularities for one or two cycles after vaccination. Maternally transferred immunity after the COVID-19 vaccine has been shown to protect the newborn from infection for up to 6 months of age, until they are eligible for the infant vaccine.
Pregnant patients should get the most up-to-date booster formulation to maximize protection against actively circulating variants.
Guidance on the COVID-19 vaccine and pregnancy is available from the CDC.
