Mild sweating after rabies vaccination can be normal. However, if the sweating is severe, it may be an adverse reaction to the vaccine. Sweating after rabies vaccination may be caused by nervousness or due to the weather, not necessarily related to the vaccine. If it is only mild sweating, you don’t need to worry too much, pay attention to observation, and supplement water appropriately. However, if sweating is severe after vaccination, especially when combined with other symptoms, such as dizziness, fatigue, nausea, diarrhea, joint pain, etc., the vaccine-induced adverse reactions should be considered. Some patients may also have skin rashes, wheals, and itchy skin, which should be considered as allergic reactions or adverse symptoms caused by the vaccine, and it is recommended that they should go to the hospital for medical treatment.
