Influenza Virus B/Austria/1359417/2021-Like Strain (B/Austria/1359417/2021, Bvr-26) and Influenza A/Vic, the active ingredient in Influvac, is a vaccine presented as an injectable solution for intramuscular and subcutaneous use. It induces immunity against seasonal influenza in individuals recommended for vaccination.

GNH USA supplies Influvac as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Influvac is a vaccine that targets the influenza virus family to prevent infection and its complications. - Seasonal influenza: reduces the incidence of flu caused by circulating influenza A and B strains. - High‑risk populations (elderly, chronic disease patients): lowers the risk of severe disease and related complications. - Healthcare workers: helps prevent transmission of influenza in clinical settings.

Common Side Effects: - Injection site pain: mild to moderate discomfort at the injection site. - Redness or swelling: localized erythema or edema. - Low‑grade fever: transient temperature rise up to 38°C. - Headache or muscle aches: mild systemic symptoms.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - Guillain‑Barré syndrome: rare neurological disorder with progressive weakness. - High fever or seizures: uncommon but potentially serious systemic reactions.

Influvac should be administered with consideration of the following precautions. - Assess allergy history: avoid in individuals with severe egg allergy or known vaccine component hypersensitivity. - Post‑vaccination observation: monitor the recipient for at least 15 minutes for immediate reactions. - Delay vaccination if acute febrile illness is present: postpone until recovery. - Avoid concurrent administration of live vaccines: separate by at least 4 weeks. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Influvac may interact with other agents that affect immune response. Major Interactions (Avoid): - Live attenuated vaccines: may interfere with immune response to either product. - Immunoglobulin therapy: can reduce vaccine efficacy. - Immunosuppressive therapy: may diminish antibody production. Moderate Interactions (Monitor Closely): - Antipyretics (acetaminophen, ibuprofen): may mask fever after vaccination. - Antihistamines: may lessen local reaction but do not affect overall immunity.
