Question
What should I do if my child starts experiencing dizziness and blurred vision occasionally after getting the Japanese encephalitis vaccine?
Answer
The Japanese encephalitis vaccine is generally made from attenuated or inactivated viruses. Overall, it is quite safe, and theoretically, there is no possibility of vaccine-induced hemolytic disease, but the chance of recurrence is very low. Common side effects of the vaccine after vaccination include fever, rash, and occasionally headache and soreness. These symptoms usually diminish over time and should gradually disappear within a few days. However, your child’s symptoms have persisted for a month and are characterized by occasional dizziness and paleness, which should not be a side effect of the Japanese encephalitis vaccine administration, nor have they damaged the nerves in the brain.
