In Prevention of Japanese Encephalitis

Japanese encephalitis is an infection of the brain caused by the Japanese encephalitis virus (JEV), a virus spread by the bite of infected mosquitoes. In most cases, the infection is mild but in serious cases the symptoms may include headache, vomiting, fever, confusion and seizures. Jenvac Vaccine works by causing the body to produce its own protection (antibodies) against the virus. This vaccine is generally recommended for individuals who are traveling to areas where this infection is common. However, while traveling, use insect repellent, wear long-sleeved shirts and pants, treat clothing and gear, and get vaccinated before traveling, if vaccination is recommended for you.

Quick tips

  • Jenvac Vaccine is given to prevent Japanese encephalitis (infection of the brain).
  • Tell your doctor if you have a fever or infection of any type before taking Jenvac Vaccine.
  • Inform your doctor if you have a bleeding or blood clotting disorder.
  • Inform your doctor if you are taking certain medicines or receiving cancer treatments.
  • Japanese encephalitis is passed to humans by the bite of an infected mosquito, so be careful and try to avoid mosquito bites.
  • Mosquitoes that carry the Japanese encephalitis virus are most active in the evening. If you go out after sunset then wear long-sleeved clothing and trousers. Light colors are better, as they are less attractive to mosquitoes.
  • Always use mosquito nets while sleeping.
  • Try to avoid using mosquito coils as the smoke coming from them might be harmful to you and your kids at home.
