Q: Is it safe to get the COVID-19 vaccine if I’m breastfeeding?
A: While there is no data on safety of COVID-19 vaccines in lactating women or the effects of mRNA vaccines on the breastfed infant or milk production/excretion, multiple societies including American College of Obstetricians and Gynecologists and the Society for Maternal-Fetal Medicine suggest it should be offered to breastfeeding women. If you are part of a group (e.g., healthcare personnel) who is recommended to receive a COVID-19 vaccination and are breastfeeding, you may choose to be vaccinated. Please review this statement from the American College of Obstetricians and Gynecologists and this statement from the Society for Maternal-Fetal for more information.
Q: Should I get the COVID-19 vaccine if I plan to become pregnant soon?
A: If you're trying to get pregnant now or hope to get pregnant in the future, you may still receive a COVID-19 vaccine. There is currently no evidence the vaccines cause fertility problems. The CDC doesn’t recommend routine pregnancy testing before COVID-19 vaccination. You also do not need to avoid pregnancy after receiving a COVID-19 vaccine. Like all vaccines, scientists are studying COVID-19 vaccines for side effects and will report additional data as it becomes available.
Q: Why can the COVID-19 vaccine cause false positives on mammograms, and should I be worried?
A: One potential side effect of the COVID-19 vaccine is swollen lymph nodes on the side of the body where you received your shot. This is a normal, temporary immune response, but it can lead to unclear mammogram results. As a result, the Society of Breast Imaging recommends you delay breast cancer screenings for four to six weeks after getting your second dose. You may also choose to schedule a mammogram before you get your first dose.
The choice is yours to make. If you have additional questions before you make a decision, please talk to your healthcare provider.
