Is it normal to have a fever after receiving the rabies vaccine?

In general, fever after receiving the rabies vaccine may be normal if it is a reaction to vaccination, but abnormal if caused by infection. Specific analysis is as follows:

1. Normal

Under normal circumstances, fever may occur after receiving the rabies vaccine, but it usually does not persist. Once the body stabilizes, the temperature gradually decreases and returns to normal levels. This type of reaction is considered normal and typically requires no special treatment.

2. Abnormal

If inflammation or infection is already present before vaccination, or if proper local care is not taken after vaccination—allowing bacteria or other microorganisms to enter—the body may develop an inflammatory response leading to fever. This situation is generally abnormal and requires timely management. Patients may take medications such as ibuprofen tablets, acetaminophen (paracetamol) tablets, or aspirin tablets under medical guidance to help reduce fever.

If patients experience any discomfort symptoms, they are advised to seek prompt medical attention at a hospital to avoid delaying diagnosis and treatment.
