Each year, the flu shot helps protect millions of people from influenza and its complications. While the vaccine is safe and effective, it’s common to have questions about what happens after you receive it. Many patients wonder what side effects are normal, how long they last, and whether there are any activities they should avoid after getting their flu shot. Here’s a complete guide to what you can expect after your flu vaccine, and how to care for yourself in the hours and days that follow.

Common Side Effects After a Flu Shot
Most side effects of the flu shot are mild and temporary, lasting only one to two days. They’re a normal sign that your body is building protection against the flu virus. Common side effects include:
- Arm soreness or tenderness at the injection site: The most common reaction, usually improving within 24-48 hours
- Mild swelling or redness at the injection site: This may look like a small bump or patch of redness and generally goes away quickly
- Low-grade fever: Some people develop a mild fever as their immune system responds
- Fatigue: Feeling a little more tired than usual is normal and typically resolves within a day or two
- Headache or muscle aches: Some people experience mild, flu-like symptoms, but they are far less severe than actual influenza
What To Avoid After a Flu Shot
While most people can return to their regular routines right away, there are a few things you may want to avoid after getting vaccinated. This includes any intense exercise or heavy lifting. Strenuous activity can increase soreness in your arm, so consider waiting 24 hours before resuming high-intensity workouts. Additionally, it’s recommended to avoid alcohol in excess. A drink or two is typically fine, but drinking heavily may interfere with your body’s ability to recover and weaken your immune response. Lastly, don’t ignore any severe symptoms. While rare, allergic reactions or unusual side effects should not be overlooked.
How To Relieve Side Effects
If you experience discomfort after the flu shot, try these simple remedies:
- Apply a cool compress to the injection site area to reduce soreness or swelling
- Use over-the-counter pain relievers such as ibuprofen or acetaminophen
- Keep your arm moving and active – light activity can reduce stiffness and soreness
- Stay hydrated and get plenty of rest to help your immune system respond effectively
Even if you experience mild side effects, the protection you gain from the flu shot is well worth it. The vaccine reduces your risk of contracting the flu, lowers the severity of symptoms if you do get sick, and helps protect vulnerable populations such as infants, older adults, and those with weakened immune systems.
