Vaccination against influenza
Infuenza or flu is a serious respiratory infection. You can get vaccinated against influenza throughout the season, but the most reliable protection is provided by vaccination before the season reaches its peak.
The influenza vaccine will take effect 10-14 days after the injection and the strongest protection generally lasts for one flu season. Immunity develops within two weeks after vaccination.
Different types of influenza viruses circulate each year, which is why it is necessary to revaccinate against influenza every year.
The flu season typically peaks between October and January. Injectable vaccines contain split inactivated flu virus that teaches the body to recognise and respond to the pathogen.
Influenza is characterized by sudden onset of symptoms. These symptoms include:
- High fever (38°C or more)
- Chills and fatigue
- Cough
- Headache
- Sore throat or muscle pain
- Breathing difficulties may occur.
- Diarrhoea may occur.
Common complications of influenza include:
- Pneumonia
- Bronchitis
- Pharyngitis
