Vaccination and Tick-borne Encephalitis, Central Europe
F. X. Heinz et al.
Tick-borne encephalitis is a disease of the brain caused by a virus found in many parts of Europe as well as central and eastern Asia. As the name indicates, the virus is spread by tick bites. The number of people infected each year varies according to complex interactions involving the ticks’ environment, the weather, and human socioeconomic and vaccination status. To determine how well vaccine protects against the disease, researchers compared the number of cases in 3 neighboring countries in which vaccination coverage differs but many other factors remain the same: Austria (where more than three quarters of the population are vaccinated) and Slovenia and the Czech Republic (where less than one quarter of the population are vaccinated). They found far fewer cases in Austria, indicating that vaccination is an excellent way to prevent this disease.
