Is it normal to start having side effects from flu shot 58hrs after receiving it- low fever, nausea, body aches.usually i get side effects much sooner?

Usually coincidental: Usually, the fever, nausea, and body aches are due to minor illnesses such as viral infections. Other causes are possible, but since typical flu shots rarely cause any reactions aside from at the location of the shot, such common symptoms like fever, nausea, or body aches are generally considered to be coincidences and have some other cause rather than a flu shot.
