How long will the vaccine fever last

After vaccination, the human body will experience symptoms such as fever, heat, vomiting, etc., which is a normal phenomenon. Generally speaking, it will last about 2 to 3 days, and the fever will subside automatically, allowing the body to return to normal. But if the fever persists, you need to go to the hospital for diagnosis and treatment as soon as possible. However, due to differences in the human body, some people will not experience symptoms such as fever after vaccination. If you have a fever, you can drink more hot water during this period, or apply ice cubes to cool down. Remember not to take medicine indiscriminately to prevent drugs and vaccines from conflicting with each other and causing worse harm.

Rabies vaccine is not one of the infant vaccines, but a vaccination against rabies. Some people will experience some discomfort symptoms after vaccination, and some will develop rashes or fever. So, what should I do if I get a fever after getting the rabies vaccine? If the fever is not serious, it is recommended to reduce the fever by yourself.

What to do if you have a fever after getting rabies vaccine

Rabies vaccine is a vaccine used to prevent rabies. The rabies vaccine currently produced in my country is made by inoculating primary hamster kidney cells with fixed rabies virus. After cultivation, the venom is harvested, concentrated, purified, refined, and added with aluminum hydroxide adjuvant. After passing comprehensive testing, it becomes a vaccine for preventing rabies.

After vaccination with rabies vaccine, anti-rabies virus antibodies may appear in human blood. These antibodies can prevent the virus from spreading directly between cells and reduce the amount of virus proliferation. At the same time, they can also eliminate free rabies viruses and prevent the virus from reproducing and spreading, thereby preventing rabies.

Some people will have a fever after receiving the rabies vaccine, which is an immune response of the body. If the fever does not exceed 38.5 degrees, there is no need to use antipyretics. Physical cooling methods such as warm water baths can be used. Pay attention and observe, the fever may be caused by other reasons such as cold. General drugs have no effect on the immune effect of vaccines, just don't use drugs such as hormones that affect immune function. Don’t worry too much. Generally, the fever will go away after the next few shots produce enough antibodies.

The role of rabies vaccination

Rabies, also known as hydrophobia, is an acute infectious disease of natural zoonosis caused by the rabies virus. The epidemic is widespread and the mortality rate is extremely high, almost 100%.

It poses a serious threat to people's life and health. Rabies is usually transmitted to humans through bites from infected animals. The clinical manifestations include unique fear of water, fear of sound, fear of wind, fear and anxiety, pharyngeal muscle spasm, progressive paralysis, etc.

The clinical manifestations of rabies can be divided into four stages.

1. Incubation period: The incubation period varies in length, with the shortest being 3 days and the longest being 19 years, and the average is generally about 20-90 days. During the incubation period, the infected person does not have any symptoms.

2. Prodromal stage: The infected person begins to experience general discomfort, low fever, headache, nausea, fatigue, followed by fear, anxiety, irritability and insomnia, and is sensitive to sound, light, wind and other stimuli and has a feeling of tightness in the throat. There are symptoms such as itching, pain, numbness, tingling and other abnormal sensations in the healing wound and its nerve supply area. This phase lasts 2-4 days.

3. Excitement stage: manifested as high excitement, with prominent features such as extreme fear expression, fear of water and fear of wind. Elevated body temperature (38-40 degrees) and hydrophobia are the characteristics of this disease, but not in every case. Although typical patients are extremely thirsty but dare not drink, seeing water, hearing the sound of water, drinking water, or just mentioning drinking water can cause severe spasm of the pharyngeal muscles. External stimuli such as wind, light, and sound can also cause pharyngeal muscle spasms, which may cause hoarseness, slurred speech, and ventilator spasms may cause breathing difficulties and cyanosis. Sympathetic nervous system hyperactivity can be manifested as profuse sweating, increased heart rate, and increased blood pressure. However, the patient is usually conscious, but may experience mental disorders and hallucinations. This issue is 1-3 days.

4. Paralysis stage: If the patient manages to survive the excitement stage, he or she will enter the coma stage. During this stage, the patient is in a deep coma, but the various symptoms of rabies are no longer obvious. Most patients who enter this stage eventually die of exhaustion. Patients often suffocate to death due to spasms in the throat.
