Question
What should be done if a two-year-old occasionally experiences dizziness and blurred vision after receiving the Japanese encephalitis vaccine, and the symptoms have persisted for a month with an increase in severity? Is it possible that the vaccine has injured the brain nerves?
Answer
The Japanese encephalitis vaccine is typically made from attenuated or inactivated viruses and is considered quite safe. The rare possibility of vaccine-induced neurological damage exists, but the likelihood is extremely low. Common side effects after vaccination include fever, rash, and occasional headaches, which usually resolve on their own within a few days. Occasional dizziness and blurred vision in a two-year-old for a month does not resemble the typical side effects of the Japanese encephalitis vaccine and does not indicate damage to brain nerves. If symptoms persist and worsen, it is advisable to consult with a pediatrician or a healthcare professional for further evaluation and treatment. Provide detailed medical history and information about the vaccination to allow the doctor to make an accurate diagnosis and provide appropriate treatment recommendations.
