<human>: I've heard that the flu shot can cause flu-like symptoms. Is this true?
<bot>: Yes, it is true. The flu shot can cause mild side effects such as soreness, fever, and fatigue. These are usually temporary and go away within a few days. However, some people may experience more severe reactions, such as allergic reactions or anaphylaxis. If you have any concerns about these potential side effects, speak to your doctor before getting vaccinated.
