Doctor's answer (1)
Dr. Zhou Xiaofeng
The Japanese encephalitis attenuated vaccine is an important measure for preventing epidemic Japanese encephalitis, and its vaccination schedule is clear and well-defined. Generally, the Japanese encephalitis attenuated vaccine requires two doses, consisting of a primary dose and a booster dose. The first dose is usually administered when the infant is 8 months old or 1 year old, serving as the initial immunization; the second dose, as a booster shot, is given when the child reaches 2 years of age. The interval between these two doses is approximately one year, ensuring the vaccine's effectiveness and long-lasting protection. Vaccination with the Japanese encephalitis attenuated vaccine can effectively prevent Japanese encephalitis virus infection and safeguard children's health. Therefore, parents should strictly follow the vaccination schedule and ensure their children receive the Japanese encephalitis attenuated vaccine on time.
