Disease description:
I’m very worried that my child might fall ill in the future, so I’ve ensured all vaccinations are completed. This week, my child received the live attenuated Japanese encephalitis vaccine. I’d like to ask the doctor: What are the adverse reactions associated with the live attenuated Japanese encephalitis vaccine?

Hello, adverse reactions to the live attenuated Japanese encephalitis vaccine include local reactions typical of live attenuated vaccines, usually occurring within 24 hours after vaccination. These reactions primarily manifest as redness, swelling, heat, and pain at the injection site. They may also cause inflammation of nearby lymph nodes and lymphatic vessels. Generally, such post-vaccination reactions resolve spontaneously within 24 hours. If local redness and swelling are severe, warm compresses may be applied—*except for BCG vaccination sites, where warm compresses are strictly contraindicated*. We hope this information is helpful to you. Wishing you a happy and healthy life!
