Short answer: No — you cannot get the flu from the flu shot. Not possible. Zero percent. ✅ Why you can’t get the flu from the flu shot The flu shot contains inactivated (killed) virus, which means: It cannot infect you It cannot multiply in your body It cannot cause the influenza illness So medically, the flu shot cannot give you the flu. ✅ Then why do some people feel sick afterward? A few normal, harmless reactions can happen as your immune system responds: Mild fever Your immune system becomes active → leads to a low-grade fever in some people. Fatigue or body aches This is a side effect, not the flu itself. Sore arm Very common due to the immune response at the injection site. You were already exposed before the shot If someone gets sick right after the vaccine, it’s often because: They were exposed to the virus a few days before the shot They caught a different virus (cold, RSV, COVID) It takes 2 weeks for the flu shot to give full protection ❗ Important note The nasal spray flu vaccine (FluMist) does contain a live-attenuated virus, but it’s weakened so much that it also cannot cause actual influenza. It may cause: Runny nose Cough Mild symptoms But not true flu illness. ✅ Bottom Line No — the flu shot does not and cannot give you the flu. You may feel mild symptoms as your immune system builds protection, but that’s a normal response — not an infection.
