What is the latest time to receive the first dose of the attenuated Japanese encephalitis vaccine?
Disease description:
Recently, my baby needs to receive the Japanese encephalitis vaccine, but I asked the clinic and they don't have the inactivated vaccine, only the live attenuated vaccine. They asked me whether I want to vaccinate my child, but I don't know if my child is old enough. May I ask, what is the latest age for administering the first dose of the live attenuated Japanese encephalitis vaccine?

Under normal circumstances, the latest recommended time for the first dose of the live attenuated Japanese encephalitis vaccine is when the infant is 8 months old. This recommendation is based on the mechanism of action of the vaccine and the developmental stage of the infant's immune system. Administration of the live attenuated Japanese encephalitis vaccine can help infants develop immunity against the Japanese encephalitis virus, thereby effectively preventing the disease. If the optimal vaccination time is missed due to special circumstances, parents should still take the infant to a hospital or health department for vaccination as soon as possible to ensure the infant's health and safety. It should be noted that specific vaccination schedules may vary depending on regional factors, policies, and vaccine supply. Therefore, parents are advised to consult local health departments or medical institutions for accurate vaccination information.
