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.
