Now I'll finish the related work. Why do you have a fever? Let me tell you this.

Why to have a fever after Japanese encephalitis B?

The first is fever, mild 37-37.5 ℃, moderate 37.6-38.5 ℃, and severe fever above 39 ℃. In addition, some babies may have headache, dizziness, general weakness, chills, nausea, vomiting, abdominal pain, diarrhea, etc. the above reactions generally subside within 24 hours, rarely lasting more than 3 days. If the baby has a severe fever, he can take antipyretic drugs. Generally, when the temperature returns to normal, other symptoms will subside. If the high fever does not subside or there are other abnormalities, They should go to the hospital in time.

Second: local side effects generally appear about 24 hours after vaccination, and the inoculation site may appear red, swelling, heat and pain. The more severe reaction can cause inflammation of lymph nodes and lymphatics nearby. The range of swollen hard nodes at the injection site can be divided into light, medium and heavy. The light ones are less than 2.5cm in diameter, the middle ones are between 2.5-5cm, and more than 5cm is considered as serious reaction. At this time, the reaction can last for several hours. If the local redness and swelling is serious, hot compress can be used (no hot compress is allowed for redness and swelling after BCG vaccination). Once in the morning and once in the evening, about 5 minutes each time. And to frequently change underwear, to avoid infection after ulceration, such as local infection can be painted purple potion.

Third: what is the difference between inactivation and inactivation of JE? The attenuated vaccine is live vaccine. The free vaccine provided by the state has a high incidence of adverse reactions, but the immune effect is good. Only one vaccination is enough. The inactivated vaccine must be replanted once every 3-5 years. Although the inactivated vaccine has less adverse reactions, the adverse reactions are higher after multiple injections;

matters needing attention

The inactivated vaccine is made of dead virus, and the paid vaccine produced by enterprises has a low incidence of adverse reactions, but it needs to be inoculated twice to reach the level of antibody against Japanese encephalitis B; In contrast, of course, live attenuated vaccine is better. It is more appropriate for babies to choose live attenuated vaccine. In addition to better immune effect, the reduction of vaccination times also means less harm to babies.
