Why choose the maternal RSV vaccination?

content
The CDC recommends ABRYSVO® if you are 32 through 36 weeks pregnant during September through January (in most of the United States) to prevent RSV in infants from birth through 6 months of age. In areas where RSV does not follow typical seasonal patterns, the recommended months for maternal vaccination may differ. Talk to your OB to see if you are eligible.

How does maternal immunization with ABRYSVO protect your baby?

content
  • Maternal immunization with ABRYSVO involves vaccinating a pregnant woman so protective antibodies can be passed to the baby through the placenta before birth.
  • During pregnancy, your body naturally passes on antibodies that help protect your baby against bacteria and viruses, like RSV, in the first few months of life, before they’re old enough to develop their own protection. Pfizer’s ABRYSVO helps your body create RSV antibodies that are passed to your unborn baby to help protect them from birth through 6 months.
  • Eligible pregnant women can choose to receive Pfizer’s RSV vaccine ABRYSVO between 32 through 36 weeks of pregnancy.

ABRYSVO should not be given to anyone with a history of severe allergic reaction (e.g., anaphylaxis) to any of its components. Vaccination with ABRYSVO may not protect all people. Click here for Important Safety Information.

Pfizer’s vaccine ABRYSVO helps protect your baby against RSV

content
ABRYSVO was studied in a clinical trial including over 7,000 pregnant women and their babies, where 3,695 pregnant women received ABRYSVO and 3,697 received a placebo. The study showed ABRYSVO reduced the risk of severe RSV by ~69% compared with placebo in infants measured at 6 months after birth.

Talk to your OB about how to protect your baby from RSV and whether ABRYSVO is right for you. To avoid the potential risk of preterm birth, ABRYSVO should only be given between 32 through 36 weeks of pregnancy.
