Arexvy (respiratory syncytial virus vaccine adjuvanted)

How It Works

Arexvy contains inactivated RSV particles along with an adjuvant to boost the immune response. When administered, the vaccine stimulates the immune system to produce antibodies against RSV. These antibodies help protect against future infections by recognizing and neutralizing the virus, thereby preventing the virus from causing severe respiratory illness.

Side Effects

• Pain at the injection site
• Redness and swelling at the injection site
• Fatigue
• Headache
• Muscle pain
• Fever

Indications

• Prevention of respiratory syncytial virus (RSV) in older adults, especially those with underlying health conditions that increase the risk of severe RSV infection

Contraindications

• Hypersensitivity to any component of the vaccine, including the adjuvant
• Severe allergic reaction (e.g., anaphylaxis) to a previous dose of Arexvy or any other RSV vaccine
• Acute severe febrile illness (vaccination should be postponed until recovery)
