Does fever play an important role after vaccination?

Fever is a body temperature which is measured higher than the normal temperature. Most of the people experience normal body temperature around 98.6ᴼF (37ᴼC). It is a temporary increase in the body temperature, frequently caused due to an illness. Some of the common symptoms of fever are general weakness, sweating, headache, dehydration, irritability, loss of appetite etc. It can be measured through digital thermometers.

Initially, vaccines develop the immune system to protect against bacteria or viruses that makes a person sick. It is a medical product, though they are invented to protect from diseases but, cause many side effects like swelling, soreness or redness at the injection site etc. It works by training the immune system to recognize and fighting pathogens, either bacteria or viruses. To perform this, certain molecules from the pathogen must be launched into the body to trigger an immune response.

Fever is a compulsory symptom after any vaccination. Vaccination is a simple, secure, and effective way of protecting people against dangerous diseases. The temperature after vaccination will decrease in 2- 3 days of time period. Vaccine uses your body’s natural defenses to raise resistance to specific infections and helps to makes your immune system stronger. It trains your immune system to create antibodies. Therefore, vaccines protect against diseases like yellow fever, typhoid, cholera, measles, polio and etc.
