Does the flu vaccination work?

Flu is a highly infectious acute respiratory illness caused by the influenza virus and it affects people of all ages. The best way to prevent catching the flu is actually by getting your flu vaccination from your GP, Pharmacy, or Occupational Health therapist. If you are carrying the virus, you can spread it by coughing or sneezing. This can happen from 1-2 days before symptoms develop and up to 5 days after symptoms develop. Believe it or not, flu can survive on worktops and objects, especially in low temperatures and low humidity. You can get flu by touching a surface with the virus on it and then touching your mouth, eyes or nose. The virus can live on a hard surface for up to 24 hours and a soft surface for around 20 minutes.

Flu symptoms come on suddenly with a fever, muscle aches, headache and fatigue. There are a number of key points to note in relation to the flu, not least that you are at increased risk if you don’t avail of the vaccination:

  •  Flu causes death and hospitalisation every year.

  •  Healthy people can have flu without any obvious symptoms and pass it on.
