The side effects (i.e. adverse reactions) of rabies vaccination can be categorized into 3 types: common, rare and extremely rare, but the occurrence and severity of these reactions vary from person to person. 1. Common adverse reactions: These include local reactions such as pain, redness, swelling and itching at the injection site, as well as systemic reactions such as mild fever, headache, fatigue, vomiting and arthralgia. Such cases generally do not require special treatment and can be relieved after a period of time. 2. Rare adverse reactions: mainly transient moderate or above (≥38.1℃) fever reaction. Such cases need to take physical or drug methods to lower the temperature in time to prevent the emergence of febrile convulsions. 3. Extremely rare adverse reactions: such as allergic rash, anaphylaxis, anaphylactic purpura, angioneurotic edema, and so on. This kind of situation must consult a doctor in time for targeted treatment. However, it should be noted that the above adverse reactions do not always occur, and the risk and severity of their occurrence are often affected by the physical condition of the user and compliance, vaccination procedures and other factors, and the specific situation may have a wide range of individual differences. People who have rabies vaccination needs must be standardized under the guidance of doctors, and pay attention to observe the reaction after vaccination, if abnormalities occur, should seek medical treatment in time. Do not blindly operate on your own to avoid adverse consequences.
