Question
I had a Japanese Encephalitis vaccination before, and the doctor mistakenly administered it again this month. What adverse reactions might occur? How long did the illness last this time, and what is the current general condition? Do you have any previous medical history, diagnosis, and treatment process? Have any auxiliary examinations been conducted?
Answer
Overreaction to the vaccine usually occurs within a week, with most cases presenting with fever symptoms. As far as I know, there should be no effect after such a long time. It is not possible to determine the impact on brain development after receiving 10 vaccinations. You still need to observe for any abnormal conditions and consider hospitalization. Children with normal immunity are unlikely to have problems, but children with poor immunity may contract Japanese Encephalitis. It is recommended to consult your local hospital for more information.
