Today more and more people have pets, and with this comes a gradual increase in bites and scratches from cats and dogs. Once you have been bitten or scratched by a dog or cat, it is best to get a rabies vaccination to prevent rabies from occurring. The earlier the rabies vaccination is given, the better the results. Usually, rabies vaccination is required within 24 hours of being scratched or bitten at an immunization station, and the dose should be doubled if the rabies vaccination is given only after 24 to 48 hours. There are some adverse reactions after rabies vaccination, which are caused by the inherent characteristics of the vaccine itself and only cause transient physiological dysfunction to the organism, and they vary from person to person. One of the adverse reactions is pain at the injection site. In addition to pain, other commonly occurring adverse reactions include redness, swelling, itching, fever, malaise, dizziness, vomiting, muscle pain, diarrhea, swollen lymph nodes, erythema and papules. Generally speaking, redness, swelling, pain and other adverse reactions at the injection site are normal and do not require special treatment, and most of them can be relieved within 24-48 hours. In addition, after the rabies vaccination, you should also pay attention to the following matters: After the rabies vaccination, pay attention to rest, avoid overexertion, do not do strenuous exercise and labor that consumes a lot of physical strength. Also pay attention to avoid getting cold and prevent catching a cold, as this may produce an overreaction. It is recommended that you should go to a regular hospital or CDC with resuscitation equipment for rabies vaccination, so that those with more serious side reactions such as allergic reactions, neurological subcutaneous edema and urticaria can be rescued and treated symptomatically in a timely manner.
