COVID-19 and Flu Vaccines During Pregnancy 

Pregnancy is an exciting time but can also be a bit overwhelming. You want the best for your baby — and yourself. We have guidance you can trust on the COVID-19 and flu vaccines and answers to common questions you may have. 

If you’re pregnant, taking precautions to prevent the flu or COVID-19 infection is especially important. Pregnant women, even those in perfect health, can become very ill if they get the flu or COVID-19. 

Flu risks increase as pregnancy progresses. Studies from the CDC have shown that this risk is reduced by getting a flu vaccine.

COVID-19 infection during pregnancy leads to increased risk of maternal severe illness, admission to intensive care, mechanical ventilation and death. Pregnant patients with underlying health conditions such as diabetes, obesity, advanced maternal age and cardiovascular disease also face a higher risk of complications from COVID-19.  

Will the flu and COVID vaccines help protect me and my baby? 

Flu shots given during pregnancy help protect both mother and baby from flu. A 2018 study showed that getting a flu shot reduced a pregnant woman’s risk of being hospitalized with flu by an average of 40%. Pregnant women who get a flu vaccine also are helping to protect their babies from flu illness for the first several months after their birth, when they’re too young to get vaccinated.  

Evidence has shown that COVID-19 vaccines are safe and effective in pregnant and non-pregnant individuals, preventing COVID-19 infection or hospitalization, and can decrease the risk of severe disease. A study conducted by the CDC from 2022-2023 showed that maternal receipt of an mRNA COVID-19 vaccine during pregnancy reduced the likelihood of COVID-related hospitalizations and serious complications among infants early in life.   

When should I get vaccinated if I’m pregnant? 

The flu vaccine can be given during any trimester of pregnancy and anytime during flu season. The ideal time is in September or October. COVID-19 vaccines can be given throughout the year and during any trimester of pregnancy.  

What do doctors advise? 

Both the California Department of Public Health (CDPH) and the American College of Obstetricians and Gynecologists recommend getting both the flu and COVID-19 vaccines if:

• You’re pregnant
• You recently had a baby
• You’re breastfeeding
• You're thinking about getting pregnant

The vast majority of experts believe both the flu and COVID-19 shots are safe and can be given in any stage of pregnancy. Sutter strongly endorses this position. If you're pregnant, talk to your doctor or midwife about the flu or COVID-19 vaccines.
