1. What is influenza?
- Influenza (or ‘the flu’) is caused by three types of influenza virus – A, B and C that infect the respiratory system.
- Influenza is contagious and is spread by coughing, sneezing and direct contact with an infected person, or by touching a contaminated surface.
2. Can the vaccine give me the flu?
- No. You cannot get the flu from the vaccine, as it does not contain any live viruses.
- However, some people may experience mild side effects such as muscle aches, headaches or a sore throat for a short time after vaccination. This is a normal reaction.
- These flu vaccine side effects usually diminish within one or two days and do not result in the flu.
3. I’m healthy – why do I need a flu vaccine every year?
There are a number of reasons why it is recommended to get the flu vaccine every year:
- Although people with underlying health conditions are most at risk from influenza associated complications, anyone among the general population can become seriously ill with the flu and even die.
- Healthy individuals who contract flu can easily pass the virus on to those whose health is compromised, such as elderly relatives.
- Each year the flu can be caused by different flu viruses, that are not included in the previous year’s vaccine.
- Protection from the flu vaccine decreases over time.
- Influenza continues to be a major threat to public health worldwide because of its ability to spread rapidly through populations.
4. How effective is the vaccine for healthy adults?
- The flu vaccine is approximately 73% effective in preventing infection with influenza A and B viruses in healthy adults under 65 years of age, when there is a good match between the vaccine and circulating influenza strains.
5. How long after vaccination does it take to start providing protection?
- It takes up to two weeks for the vaccine to give full protection.
6. How long does the immunisation (vaccine protection) last?
- Protection should last throughout the flu season, approximately 9 months.
7. Can’t I build up a natural immunity to influenza?
- Immunity develops after you have been exposed to a particular strain of the virus through infection or immunisation.
- Flu immunisation prepares and boosts your immune system to help you fight the flu viruses expected to be circulating each year.
8. Does the vaccination contain thiomersal or mercury?
- No. It does not contain thiomersal (or any other mercury product).
