Can flu shot cause vomiting?

I completely understand how awful and scary it feels to start throwing up after getting a vaccine, it makes you regret getting it in the first place. Nausea can sometimes happen due to anxiety or a mild immune reaction. Please rest, sip on electrolyte water, and consult a doctor if it doesn't stop.

While mild symptoms like fever or soreness are expected, severe vomiting is quite rare after a flu shot. Sometimes it can just be an coincidental stomach bug or a reaction to the anxiety of the injection itself. Please stay hydrated with ORS and see a physician if the vomiting continues.

I actually felt super nauseous and threw up once after my flu shot last year. My doctor said it can occasionally happen due to the body's immune response or simple nervousness. It stopped after a few hours of rest, but if you can't keep any fluids down, definitely visit a doctor.

I faced mild nausea and vomiting after my annual shot once, and my physician told me it is a rare but possible systemic reaction. My tip is to avoid heavy meals immediately after the shot and stick to simple coconut water or ginger tea. If it goes beyond a couple of episodes, seek medical advice.
