Is Fever Normal After Taking COVID-19 Vaccine?

A fever is when our body temperature exceeds the baseline temperature. Our body’s average temperature is around 98.6ᴼF or 37ᴼC, but it varies from person to person. Plus, this baseline temperature fluctuates throughout the day. A rise in body temperature is one of the vaccination’s most common side effects, including the COVID-19 vaccine. However, fever is no reason to skip vaccination. Both COVID-19 testing and vaccination are crucial to ensure safety during the pandemic. 

Here’s a guide to explain why some people get fever after getting a COVID-19 jab and why it is totally normal.

Why do people get fever after taking any kind of vaccine? 

Antigens present in the vaccine trigger the body’s immune response. Hence, the blood flow in the body increases to accelerate the supply of defensive immune cells throughout the body. The result of all this is an increase in body temperature or fever. People get easily scared of high or even moderate fever because they are related to various serious illnesses. While in reality, getting a fever after getting a vaccine is entirely normal, and it means your immune system is active and at work. 

Post-COVID-19 Vaccine Fever

Vaccines contain a controlled amount of inactivated virus injected into the body, which prepares the immune system to defend the body from actual infection. Therefore, it is necessary to take the vaccine to prevent the infection and transmission significantly. COVID-19 is a highly curable disease for a large percentage of the population. Thus, it is paramount that people take the recommended dosage of the vaccine as early as possible to build their immunity. Besides, RT-PCR COVID-19 and rapid COVID-19 tests are equally essential if you experience other viral infection symptoms.

When should you expect the fever to appear after taking the vaccine?

Most fevers after vaccination occur within a week or two. However, the effects of the vaccine may vary among people due to differences in individual immune responses. Also, as some vaccines need more than one dose to work effectively, the fever is likely to be more severe after the second or third dose. But this fever should not last more than a couple of days at the most. If the fever seems out of control, you should consult a doctor or get a rapid COVID-19 test or RT-PCR test is done to confirm the cause of the prolonged fever.

Follow the CDC Guidelines to Know More About What Should You Expect 

According to the CDC guidelines, getting a fever ranging from mild to severe after getting the vaccination is entirely normal. However, if it starts to hamper your daily life and severely affect your health and wellbeing, then you have to visit a doctor or go to the nearest hospital or testing center. Get RT-PCR tests done to confirm if you have COVID or not. You can visit the CDC website to know more about this topic and know more about the side effects of the COVID-19 vaccine.
