Can a Flu Shot Make You Tired?

December 22, 2022

Flu season has arrived and as we near the holiday, it’s more important than ever to be informed on the effectiveness of the flu vaccine. Influenza, or the flu, is a highly contagious virus that can lead to mild to severe illness, and in some cases, even death. An annual flu shot is the best way to protect yourself and others from getting sick with flu-like symptoms. However, like any medication, the flu shot has a few mild side effects. 

At AFC Urgent Care Aurora Saddle Rock, our medical providers are experienced in administering flu shots seven days a week. To prevent contracting influenza and spreading it to your loved ones, bring your entire family into the walk-in clinic to be properly vaccinated. 

Can flu vaccination cause fatigue?

With the rise of flu season, many questions begin to rise across the nation about the shot’s side effects. You may be wondering, can flu shots make you tired? The answer to this is both yes and no. While it’s possible that a flu shot could make you feel tired, this is not one of the most common side effects. Side effects of a flu shot typically include soreness, redness, and swelling at the injection site. Some people may also experience a low-grade fever, headache, muscle aches, and nausea. However, these side effects are short lived, and in no comparison to the symptoms of influenza itself.

That said, there is a small chance that you could feel mildly fatigued after getting a flu shot. This could result as the body is working to produce antibodies. Antibodies build immunity against the virus, which can cause fatigue or tiredness. However, this is typically mild and should subside within a few days. If you do experience fatigue after getting a flu shot, we recommend staying hydrated and getting plenty of rest. However, if your fatigue persists or worsens overtime, it is important to seek the appropriate medical attention.

How to Best Prevent Influenza 

The flu shot does not contain any live viruses, so it cannot cause you to actually get the flu. In fact, getting a flu shot is the best way to prevent influenza. Flu symptoms are sudden and generally much worse than the side effects of vaccination. Symptoms of flu include fever, chills, muscle aches, headaches, fatigue, coughing, and sore throat. It is important to seek medical attention if you experience any of these symptoms, as the flu can lead to more serious illnesses, such as pneumonia. 

Beyond getting your annual flu shot, you can prevent the spread of the flu by washing your hands regularly and avoiding close contact with people who are sick. The holiday season can be an increasingly difficult time to avoid large crowds, making the flu shot even more important than usual. If you do become ill, there are several treatments available to help alleviate your symptoms and speed up your recovery. The medical providers at AFC Urgent Care Aurora Saddle Rock can help patients discuss treatment regimens and suggest symptom relief via over-the-counter medications that can be used to reduce fever and pain. 

Can you be allergic to a flu shot?

Although rare, it is possible to be allergic to a traditional flu shot. If you’re allergic to eggs, be sure to inform your medical provider prior to vaccination as many flu shots contain egg products. Additionally, those who have developed Guillain-Barre Syndrome should consult with their provider about additional forms of prevention. 

Signs of a severe allergic reaction can include, but are not limited to:

  • Difficulty breathing
  • Hoarseness or wheezing
  • Swelling around the eyes or lips
  • Hives
  • Paleness
  • Weakness
  • A fast heart beat or dizziness
