The following vaccines are recommended during pregnancy by the CDC and the American College of Obstetricians and Gynecologists (ACOG):
Influenza (Flu) Vaccine
Recommended once during pregnancy for all women, in any trimester, during flu season (September 1–March 30).
Infants cannot receive influenza vaccination until 6 months of age; maternal vaccination provides passive protection during this period.
RSV Vaccine
Recommended during RSV season (September 1–January 31) if the patient is 32 0/7 through 36 6/7 weeks gestation.
Maternal immunization provides passive antibody transfer, reducing the risk of severe RSV disease in infants.
Vaccination is ideally administered between 35 0/7 and 36 6/7 weeks gestation, as recommended by Nurture Women’s Health, to optimize antibody transfer and minimize theoretical risk of preterm labor.
Not recommended ≥37 0/7 weeks, due to insufficient time for antibody development and transfer.
Tdap Vaccine
Recommended from 27 0/7 – 36 6/7 weeks
Provides maternal antibody production against tetanus, diphtheria, and pertussis; antibodies are transferred to the fetus and continued through breastfeeding.
Administration
All vaccines should be obtained through local pharmacies. Prescriptions are generally not required.
