Frequently Asked Questions
How serious is flu?
Flu is often self limiting with most people recovering in 2-7 days. However, flu can be severe and can cause serious illness and death, especially in the very young and in the elderly. Serious respiratory complications can develop, including pneumonia and bronchitis, to which older people and those with certain chronic medical conditions are particularly susceptible. Pregnant women have also been found to be at increased risk of the complications of flu. Some people may need hospital treatment and a number of mainly older people die from influenza each winter.
How do people catch flu?
Flu is a highly infectious illness. A person carrying the virus can spread the illness by coughing or sneezing. A person can spread the virus from 1-2 days before they develop symptoms and for up to a week after symptoms develop.

Seasonal flu vaccine helps the person’s immune system to produce antibodies to the flu virus. When someone who has been vaccinated comes into contact with the virus these antibodies attack the virus.
How effective is seasonal flu vaccine?
Seasonal flu vaccine prevents flu illness in approximately 70% – 90% of people.
The effectiveness varies depending on the age and health of the person being vaccinated and the strains of flu virus that are circulating. Older persons and those with certain long term diseases have lower immune responses so the vaccine may not be as effective but it will still prevent severe illness and hospitalisation.

In the Northern hemisphere the flu season lasts from October to the end of April. Flu vaccine is recommended for all those in the at risk groups until the end of April Women who become pregnant at any stage during the flu season should get flu vaccine.

The vaccine should be given in late September/October each year.
What should I expect after vaccination?
The most common side effects will be mild and will include soreness, redness or swelling where the injection was given. Headache, fever, aches and tiredness may occur. Some people may experience mild sweating and shivering as their immune system responds to the vaccine but this is not flu and will pass in a day or so.
How long does it take the vaccine to work?
The vaccine starts to work within two weeks.
Who should NOT get seasonal flu vaccine?
The vaccine should not be given to those with a history of severe allergic (anaphylaxis) reaction to a previous dose of the vaccine or any of its constituents.
What about people with egg allergy?
People with egg allergy can get seasonal flu vaccine. This may be given by your GP or you may need referral to a hospital specialist.
