Inactivated Influenza Vaccine

Uses of Inactivated Influenza Vaccine

Inactivated Influenza Vaccine is a vaccine used to help protect against seasonal influenza (flu).

It is commonly used for:

  • Seasonal flu prevention: Helps reduce the risk of contracting influenza during the flu season.
  • Protection in high-risk groups: Recommended for individuals at higher risk of flu complications, such as older adults, pregnant women, and those with chronic health conditions, as advised by your doctor.
  • Reducing flu severity: Helps lower the risk of severe illness and complications if infection does occur.
  • Annual immunisation: Used as part of yearly vaccination schedules, as flu virus strains change from year to year.

Side effects of Inactivated Influenza Vaccine

  • Soreness, redness, or swelling at the injection site

  • Headache

  • Low-grade fever

  • Nausea

  • Muscle aches

How Inactivated Influenza Vaccine works

  • The Inactivated Influenza Vaccine works by training the immune system to recognise and fight the influenza virus.
  • It contains inactivated (killed) flu virus particles or specific viral proteins that cannot cause infection.
  • When given, the immune system responds by producing antibodies against these viral components. If the body is later exposed to the actual flu virus, these antibodies help recognise and neutralise it more quickly, reducing the risk and severity of infection.
