If you are pregnant during flu season, you should have a flu shot as soon as it’s available. We also recommend that you stay up-to-date with any needed COVID booster shots and you can receive this vaccine during pregnancy if needed. Seasonal flu and COVID infections are a leading cause of maternal death and pregnancy complications and these vaccines are highly effective and safe. If you are between 32-36 weeks’ gestation during the months of September to January, you should also receive the RSV vaccine to protect your newborn against RSV infection in those peak months after birth. We also recommend the Tdap vaccine during pregnancy to protect you and your newborn against whooping cough (pertussis). We recommend this between 27-36 weeks’ gestation to optimize the production and transmission of antibodies across the placenta to protect your newborn. If you happen to receive this shot earlier in pregnancy for some reason (maybe you stepped on a nail), you don’t need to repeat it later.
