Health Centres - FSME-Immun
How does it work?
This vaccine contains inactivated tick-borne encephalitis virus. It works by stimulating the body's immune response, without causing the disease.
What is it used for?
- Vaccination against tick-borne encephalitis
Warning!
- You may experience a fever of 40ºC or more after receiving this vaccine, particularly after the first dose. This normally subsides after 24 to 48 hours. You should measure your temperature at regular intervals for at least 24 hours after you have been vaccinated. (Parents should measure their children's temperature.) If you feel it necessary, or if temperature rises above 39ºC, you should use a medicine such as paracetamol and other cooling methods such as cold drinks and flannels to bring the fever down.
- Tick bites can also cause infection with Borrelia bacteria, which cause Lyme disease. This vaccine only provides immunity against infection with the tick-borne encephalitis virus, and does not provide protection against Borrelia infection.
