Arexvy is a brand-name respiratory syncytial virus (RSV) vaccine. It’s used in some adults to help prevent lung disease from RSV. Arexvy should not be used during pregnancy and breastfeeding.

Keep reading for specific information about reproductive health and the Arexvy vaccine. For a comprehensive look at Arexvy, see this article.

If you can become pregnant, it’s important to consider whether Arexvy is a safe choice for you.

Arexvy should not be used during pregnancy. In one study that included pregnant people who received an investigational RSV vaccine similar to Arexvy, there was an increase in preterm births.

The Centers for Disease Control and Prevention (CDC) currently recommends women who are pregnant get a different RSV vaccine called RSVpreF (Abrysvo). This vaccine is given in the third trimester of pregnancy (weeks 32 through 36).

Note: Arexvy isn’t approved for people under 50 years old. If you’re planning a pregnancy or can become pregnant, talk with your doctor before receiving this vaccine.

The risk of lung disease and other complications from RSV is higher in certain people, including infants. To help immunize the baby from disease before birth, the CDC recommends that pregnant people receive an RSV vaccine.

However, Arexvy is not intended for use in pregnant people. The only RSV vaccine that’s approved for use during pregnancy is Abrysvo.

For more information about receiving Abrysvo during pregnancy, talk with the healthcare professional providing your maternal care. A pharmacist may also be able to help answer questions you have.

Note: Both Abrysvo and Arexvy are approved to help prevent lung disease from RSV in older adults of a certain age. But as stated just above, only Abrysvo is approved for use in pregnant people.

If you’re breastfeeding or planning to do so, it’s important to consider how Arexvy may affect you and your child.

It’s not known whether Arexvy should be taken while breastfeeding. If you’re currently breastfeeding or planning to do so, talk with your doctor before receiving this vaccine.
