Fever after rabies vaccination is recommended to be treated according to the severity of the fever, and subsequent rabies vaccinations need to be continued to avoid infection with the rabies virus. Rabies vaccination stimulates the body’s immune system to react against rabies virus infection. It is normal to have a fever after rabies vaccination, and fever-reducing medications such as ibuprofen and acetaminophen can be taken to lower the temperature. It is normal for fever and other adverse reactions to rabies vaccination to subside within a few days. Subsequent rabies vaccinations are usually unaffected by this condition. The consequences of rabies virus infection are very serious, so it is very important that the entire course of rabies vaccination is taken seriously.
