Influenza (Flu) Vaccination

Influenza (also known as flu) is a potentially serious disease caused by airborne viruses usually in the cold winter seasons.  During every flu season throughout the world, influenza infection can affect millions of people.  The best way to help protect against flu is to have a yearly flu vaccination.

Symptoms of Flu Infection

The symptoms of mild flu infection are;

  • high fever
  • sore throat
  • cough
  • chills and rigors
  • body and muscle aches
  • tiredness and fatigue
  • headache

However in vulnerable people, flu can spread to cause middle ear or lung infections as well as bronchitis and pneumonia which requires hospitalisation and even death.

Benefits of Flu Vaccination

Although one may still get infected after vaccination, the flu vaccination has been shown to reduce the severity of illness in these people.  Vaccination reduces the length of intensive care unit (ICU) admissions, duration of hospitalisation and death especially in people with chronic heart or lung conditions.

How does Flu Vaccination work?

Flu vaccines gets the body to start making antibodies around two weeks after vaccination. These antibodies provide protection against flu virus infection.  The quadrivalent flu vaccine protects against 4 different flu viruses; namely 2 influenza A viruses and 2 influenza B viruses while the trivalent flu vaccine protects against 2 influenza A viruses and 1 influenza B virus.
