The following reactions may occur after rabies vaccination: First, there may be a feverish reaction on the body, which is usually low and rarely exceeds 38°C. The symptoms will disappear slowly after the vaccine is absorbed. Secondly, there may be some irritation to the injection site, resulting in local soft tissue redness and pain, but after the soft tissue has absorbed the vaccine, the redness and swelling will subside after 1-2 days of injection. Third, there may be allergies, such as redness, swelling, itching, generalized macular rash or rash like a wind cluster, and if the allergy is very serious, it may lead to low blood pressure and shock.
