Question
Please tell me about the new Japanese Encephalitis Vaccine. I heard that recently, Vietnam has imported a new batch of Japanese encephalitis vaccine called imojev and can be given to children from 9 months old, which is earlier than the old one. However, there is not much information about this vaccine. Please ask the doctor to provide more information so that mothers like me have more choices. Thank you brothers and sisters!

Hi there. Japanese encephalitis is an infectious disease that circulates in Vietnam often in the summer, so it is also known as summer encephalitis. The disease often leaves severe sequelae and even causes death. The disease is common in children < 15 years old, especially between the ages of 2 and 7 years old.
Currently, the Japanese Encephalitis vaccine is the Jevax vaccine included in the national expanded vaccination program and injection service at medical facilities throughout the country. Schedule 3 injections, 1st dose when the child is from 12 months old.
Since 2019, a new Japanese encephalitis vaccine called Imojev vaccine produced by international pharmaceutical company Sanofi Pasteur using advanced technology has been used at a number of vaccination centers in Vietnam. Japanese encephalitis vaccine imojev helps contribute to early immunity, gives high protection efficiency, and limits side effects. Imojev is being used in national immunization programs in Australia, Taiwan, Thailand, and Malaysia.
New Japanese encephalitis vaccine, given as early as 9 months old, helps protect against disease earlier than the old generation Jevax vaccine. About the vaccination schedule:
Japanese encephalitis vaccine Imojev injects a basic dose of 0.5ml of reconstituted vaccine to people 9 months of age and older. Give your child a booster dose 12 to 24 months after the primary dose. According to the manufacturer's instructions, this vaccine can be given to adults over 18 years of age as a single dose without the need for a booster. Alternatively, you can use the Japanese encephalitis vaccine Imojev as a booster for children who have received the primary dose of the inactivated Japanese encephalitis vaccine jevax.
