Japanese encephalitis is a severe viral infection transmitted to humans by nocturnal mosquitoes from waterfowl or pigs. The disease shows a clear seasonality during and shortly after the rainy season. The disease occurs mainly in Asia.
More than 90% of infections are not noticed. However, in some cases - especially in children - the infection leads to encephalitis with headaches, seizures and clouding of consciousness and even death.
Vaccination against Japanese encephalitis is one of the travel vaccinations. If you are planning a trip to South, Southeast or East Asia and your journey will take you to rural areas during the rainy season and the weeks after, you should consider vaccination. In addition, vaccination against Japanese encephalitis is recommended for long-term stays and if you expect to stay near rice fields and pig farming.
The vaccination against Japanese encephalitis is an inactivated vaccine. Two vaccinations at intervals of four weeks are necessary for effective protection. If you are in a hurry due to a spontaneous trip, there is also a rapid vaccination schedule. For long-term protection, a booster is given after 12-24 months or at the latest before the next trip.
The side effects of the vaccine are mainly local (including swelling and redness at the injection site). Occasionally there is headache or muscle pain.
To find out which vaccinations are useful for your planned trip, simply make an appointment for a travel medicine consultation at one of our Avi Medical practices and discuss with our medical team.
