Who should have the Japanese encephalitis vaccine?

If your travel plans involve visiting a region where Japanese encephalitis is endemic, it is advisable to contemplate getting the Japanese Encephalitis vaccine. The endemic areas span a considerable geographic region, encompassing the East and Western Pacific islands like Japan and the Philippines, extending to India and the western end of Pakistan. Furthermore, the endemic zone includes northern China, reaching up to the Tibet region, and stretches to Papua New Guinea and Northern Australia, a distribution that has been observed since the 1990s.

Vaccine Effectiveness

According to the World Health Organization, the Japanese encephalitis vaccine boasts a high efficacy rate of 99.3%. A singular dose of the vaccine proves highly effective in preventing Japanese encephalitis, even when administered just days or weeks before potential exposure to the virus.
While the vaccine offers significant protection, it’s advisable to take additional precautions, including the use of mosquito netting, insecticide, wearing loose-fitting clothing, long sleeves and socks, and utilizing air conditioning where available, to further minimize the risk of exposure to the virus.

What causes Japanese Encephalitis?

Japanese encephalitis is triggered by the flavivirus and is transmitted from animals to humans via mosquito bites. The virus was initially identified in pigs and birds, which served as the primary sources for transmitting the disease through Culex mosquitoes. These mosquitoes tend to breed in water pools and flooded rice fields. Their biting activity is most prevalent during the night and at sunset.

Crucially, the virus cannot be transmitted directly from person to person; the sole mode of transmission is through a mosquito bite.
