Getting a flu shot is one of the best ways to protect yourself and your loved ones from seasonal influenza. However, it’s common for people to experience mild flu-like symptoms after vaccination. These side effects are usually a sign that your body is building immunity, not that you are sick. Understanding how long these flu shot symptoms last and which ones are normal can help ease your worries and prepare you for what to expect after vaccination.
If you haven’t gotten your annual flu shot, it’s not too late! Flu season lasts from early fall through the spring months, and the flu shot is the best way to protect yourself and your loved ones from a severe case of the flu.

Common Side Effects of the Flu Vaccine
The flu vaccine can cause a few temporary side effects as your body responds to the inactivated virus. It is important to know that the flu shot cannot make you sick with the flu because the virus in the vaccine is dead. These symptoms are just a sign that your immune system is reacting and building up immunity to the virus.
Below are some of the most common side effects of the flu shot:
Headaches
Mild headaches are a common reaction to the flu shot and are generally short-term. They occur because your immune system releases chemicals that help fight infection, which can trigger temporary inflammation. Staying hydrated, resting, and taking over-the-counter pain relievers can help ease this discomfort.
Fever
A low-grade fever is another sign that your immune system is responding to the vaccine. It is usually nothing to worry about and should resolve within 24 to 48 hours. To stay comfortable, drink plenty of fluids, wear lightweight clothing, and rest as much as possible. However, if your fever exceeds 102°F (38.9°C) or lasts several days, seek medical attention.
Nausea
Some people may feel slightly nauseated after receiving the flu shot, especially if they’re anxious or sensitive to vaccines. This symptom often disappears within a few hours. Eating light meals and drinking clear fluids can help calm your stomach. Persistent nausea or vomiting, however, may require a doctor’s evaluation.
How Long Do Flu Shot Side Effects Typically Last?
Most flu shot side effects are mild and short-lived, typically lasting one to three days. Some people may not experience any symptoms at all, while others might notice soreness at the injection site, a low-grade fever, or fatigue for a day or two. These symptoms usually appear within 24 hours of getting the shot and fade as your immune system adjusts. If symptoms last longer than three days or worsen over time, it’s best to consult a healthcare professional to rule out infection or an allergic reaction.
Is It Possible to Have an Allergic Reaction to a Flu Shot?
Although rare, allergic reactions to the flu vaccine can occur. Signs include rash, swelling of the face or throat, difficulty breathing, or dizziness. These reactions usually happen within minutes to hours after vaccination and require immediate medical care. People with severe egg allergies or previous vaccine reactions should discuss alternative vaccine options with their doctor.
