The rabies vaccine is a vaccine given to prevent the occurrence of rabies. Some people may experience some uncomfortable symptoms after the vaccine, including rash and fever. Since fever after rabies vaccination is a normal adverse reaction, it usually does not last long and does not require excessive stress and can recover naturally within 3 days. So what can be done to help lower the body temperature and reduce the discomfort caused by the fever? Physical cooling can be given to the patient Put a towel soaked in cold water on the forehead, face, armpits or groin of the patient and other large blood vessels, which can lower the temperature of the blood vessels and help reduce the patient’s fever. You can also take a full body warm water bath or bath to cool down the fever, but pay attention to control the bath time, not too long to avoid increasing discomfort. Pay attention to replenish water Patients in the case of fever, body water is easily lost due to the increase in body surface temperature, appropriate replenishment of body water to avoid dehydration. At the same time, the amount of urine will increase after drinking more water, and the heat will be excreted out of the body with urine, playing a cooling effect. Pay attention to ventilation and heat dissipation Pay attention to the room temperature, make sure that the room is ventilated more often, so that the room air is convective, and untie the collar and outer layer of clothing, which is conducive to heat dissipation and cooling. Use antipyretic medication Some people may have fever after receiving rabies vaccine, which is an immune reaction of the body. There is no need to worry too much, as the fever will stop after the next few shots have produced sufficient antibodies. However, it is important to watch for other causes of fever, such as colds. If the temperature does not drop after the physical cooling measures mentioned above, and if the fever persists, you should go to the hospital promptly to be seen by a professional doctor.
