Why does fever occur after taking live attenuated Japanese encephalitis vaccine

Generally, if the baby has a fever after vaccination, many parents will be worried. In fact, fever is a normal phenomenon after vaccination. At this time, you just need to let the baby drink more water and rest more. However, if the fever persists, you should also pay attention to taking the baby to the hospital for examination in time to understand the actual situation and carry out fever reduction treatment.

1. It is normal to have a fever after getting a vaccination, because the vaccine itself is a virus with reduced activity, and there will inevitably be certain side effects after vaccination. Let your baby drink more boiled water and rest more. You can also put thin slices of raw potato on the needle hole to absorb the swelling. Pay attention and observe. If the fever is above 38.5 degrees, please go to the hospital for diagnosis and treatment.

2. Taking a bath may help cool down low-grade fever caused by high ambient temperature, but it is best not to take a bath after vaccination, at least not within 4 hours. You can wipe your body.

3. The normal basal body temperature of children is 36.9℃~37.5℃. Generally, when the body temperature exceeds the basal body temperature by more than 1°C, it is considered a fever. Among them, low fever refers to body temperature fluctuating around 38°C, and high fever refers to body temperature above 39°C. Continuous fever for more than two weeks is called long-term fever.

4. If the temperature is below 38.5 degrees, do not take antipyretic medicine or get antipyretic injections, and let your baby drink more water. Pay attention to whether the ambient temperature is too high. In the hot summer, the temperature is very high and the baby's ability to regulate its own body temperature is poor. When the mother holds the baby, the heat is not easy to dissipate, causing the body temperature to rise. However, this kind of fever usually does not last too long. Put the child in a cool place, fan him slightly, give him some cool fruit juice, or give him a warm bath, and the body temperature will return to normal after a few hours. In winter, if the indoor temperature is too high and the baby is wrapped too much, the baby's body temperature will also rise.
