ABRYSVO® is the only maternal vaccination to help protect infants against RSV from birth through 6 months1,2

ABRYSVO is a vaccine indicated for active immunization of pregnant individuals at 32 through 36 weeks gestational age for the prevention of lower respiratory tract disease (LRTD) and severe LRTD caused by respiratory syncytial virus (RSV) in infants from birth through 6 months of age.

ABRYSVO is a vaccine indicated for active immunization of pregnant individuals at 32 through 36 weeks gestational age for the prevention of lower respiratory tract disease (LRTD) and severe LRTD caused by respiratory syncytial virus (RSV) in infants from birth through 6 months of age.

ABRYSVO is recommended for pregnant individuals as a one-time dose at 32 through 36 weeks of gestation using seasonal administration (September 1 through January 31 in most regions of the U.S.). In jurisdictions with RSV seasonality that differs from most of the continental U.S., including Alaska, southern Florida, Guam, Hawaii, Puerto Rico, U.S.-affiliated Pacific Islands, and U.S. Virgin Islands, providers should follow state, local, or territorial guidance on timing of maternal RSV vaccination.4

Important Safety Information
  • Do not administer ABRYSVO to individuals with a history of a severe allergic reaction (e.g., anaphylaxis) to any component of ABRYSVO
  • The results of a postmarketing observational study suggest an increased risk of Guillain-Barré syndrome during the 42 days following vaccination with ABRYSVO
  • A numerical imbalance in preterm births was observed compared to placebo in 2 clinical studies. Data are insufficient to establish or exclude a causal relationship between preterm birth and ABRYSVO. To avoid potential risk of preterm birth with use of ABRYSVO before 32 weeks of gestation, administer to pregnant individuals at 32 through 36 weeks gestational age
  • Appropriate medical treatment must be available in case of an anaphylactic reaction
  • Syncope (fainting) may occur with administration of injectable vaccines, including ABRYSVO. Procedures should be in place to avoid injury from fainting
  • Immunocompromised individuals, including those receiving immunosuppressive therapy, may have a diminished immune response to ABRYSVO
  • Vaccination with ABRYSVO may not protect all recipients
  • In clinical trials with adults aged 60+, the most commonly reported (≥10%) adverse reactions were fatigue (15.7%), headache (12.9%), pain at the injection site (10.6%), and muscle pain (10.2%)  
  • In clinical trials with adults aged 18-59, the most commonly reported (≥10%) adverse reactions were pain at the injection site (35.3%), muscle pain (24.4%), joint pain (12.4%), and nausea (11.8%)
  • In clinical trials with pregnant individuals, the most commonly reported (≥10%) adverse reactions were pain at the injection site (40.6%), headache (31.0%), muscle pain (26.5%), and nausea (20.0%)  
  • In clinical trials with infants born to pregnant individuals, low birth weight (5.1% ABRYSVO vs 4.3% placebo) and neonatal jaundice (7.3% ABRYSVO vs 6.9% placebo) were observed
