Doctor's answer (1)
Dr. Zhou Xiaofeng
The live attenuated Japanese encephalitis vaccine is primarily used to prevent Japanese encephalitis and is generally safe and effective. It may also cause some mild to moderate adverse reactions. Common reactions include:
1. Injection site reactions: After vaccination, mild pain, redness, swelling, or tenderness may occur at the injection site.
2. Systemic reactions: Some individuals may experience mild fever, headache, fatigue, or muscle pain, which usually resolve spontaneously within a few days.
3. Allergic reactions: In rare cases, some individuals may be allergic to vaccine components, presenting as rash, difficulty breathing, or anaphylactic shock.
Although these reactions are transient, individuals experiencing persistent discomfort or severe reactions after vaccination are advised to seek medical attention promptly.
