Influvac is a vaccine that targets influenza viruses to provide prophylactic protection. Seasonal influenza: reduces the risk of infection with circulating influenza A and B strains. Community outbreaks: contributes to herd immunity, helping lower transmission rates during flu season. High‑risk groups: offers added protection for elderly persons, young children, and individuals with chronic medical conditions.

Common and serious adverse reactions may occur after vaccination with Influvac.

Common Side Effects: - Injection site pain - Redness or swelling at injection site - Low‑grade fever - Headache - Muscle aches - Fatigue

Serious or Rare Side Effects: - Anaphylactic reaction - Severe allergic response (e.g., angioedema) - Guillain‑Barré syndrome - High fever (>40°C) - Seizures - Acute respiratory distress

Before administering Influvac, consider the following precautions to ensure safe use. - Allergy assessment: avoid vaccination in individuals with known hypersensitivity to any vaccine component. - Pregnancy: consult a healthcare professional; vaccine may be administered when benefits outweigh potential risks. - Immunocompromised patients: vaccine may elicit a reduced immune response; monitor effectiveness. - Post‑vaccination fever: treat with antipyretics if discomfort occurs. - Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Influvac may interact with certain therapies that affect immune function or vaccine efficacy.

Major Interactions (Avoid): - Immunoglobulin therapy: may neutralize vaccine antigens, diminishing immune response. - Live attenuated vaccines: concurrent administration can interfere with immune response; schedule separately.

Moderate Interactions (Monitor Closely): - Antipyretic medications (acetaminophen, ibuprofen): prophylactic use may blunt antibody production. - High‑dose corticosteroids: can suppress vaccine‑induced immunity, reducing effectiveness. - Antihistamines: may mask mild allergic reactions, requiring observation.
