Covid vaccine side effects: Is feeling tired a side effect of the Covid vaccine?

It’s normal to develop some side effects from having the Covid vaccine, including fatigue.

But if the symptoms are getting worse, or you’re worried about your side effects, you should consider calling 111.

Of course, your tiredness may also be caused by something else, and isn’t necessarily linked to the vaccine.

Tiredness could be caused by obesity, being underweight, pregnancy, sleep apnoea, anaemia, and even an underachieve thyroid.
