  • 78.8% (95% CI, 52.6, 92.0; 7/12,469 in AREXVY vs 48/12,498 in placebo) against severe RSV-LRTD
  • 80.5% (95% CI, 54.0, 93.2; 6/12,469 in AREXVY vs 48/12,498 in placebo) in RSV A-LRTD, 59.7% (95% CI, 35.8, 75.5; 24/12,469 in AREXVY vs 90/12,498 in placebo) in RSV B-LRTD
  • 65.4% (95% CI, 40.4, 80.9; 17/6963 in AREXVY vs 74/6981 in placebo) in participants aged 60-69, 74.9% (95% CI, 48.4, 89.2; 9/4489 in AREXVY vs 55/4489 in placebo) in participants aged 70-79

Vaccine Efficacy (VE) for ≥80 years cannot be reliably estimated due to the low number of cases accrued in this age group.1,2

SAFETY INFORMATION

Indication & Important Safety Info

Indication

Important Safety Information

Indication

AREXVY is a vaccine indicated for active immunization for the prevention of lower respiratory tract disease (LRTD) caused by respiratory syncytial virus (RSV) in:

  • individuals 60 years of age and older;
  • individuals 50 through 59 years of age who are at increased risk for LRTD caused by RSV.

Important Safety Information

  • AREXVY is contraindicated in anyone with a history of a severe allergic reaction (eg, anaphylaxis) to any component of AREXVY
  • The results of a postmarketing observational study suggest an increased risk of Guillain-Barré syndrome during the 42 days following vaccination with AREXVY
  • Appropriate medical treatment must be immediately available to manage potential anaphylactic reactions following administration of AREXVY
  • Syncope (fainting) may occur in association with administration of injectable vaccines, including AREXVY. Procedures should be in place to avoid injury from fainting
  • Immunocompromised persons, including those receiving immunosuppressive therapy, may have a diminished immune response to AREXVY
  • In adults 60 years of age and older, the most commonly reported adverse reactions (≥10%) were injection site pain (60.9%), fatigue (33.6%), myalgia (28.9%), headache (27.2%), and arthralgia (18.1%)
  • In adults 50 through 59 years of age, the most commonly reported adverse reactions (≥10%) were injection site pain (75.8%), fatigue (39.8%), myalgia (35.6%), headache (31.7%), arthralgia (23.4%), erythema (13.2%), and swelling (10.4%)
  • There are no data on the use of AREXVY in pregnant or breastfeeding individuals. AREXVY is not approved for use in persons <50 years of age
  • Vaccination with AREXVY may not result in protection of all vaccine recipients
