I took covishield 1st dose yesterday at 12.00 afternoon, after taking vaccine around at evening 7 o clock i started to have a mild lower back pain with injection side pain and tenderness. But at night i had a low grade fever, burning eyes, chills, light weakness and body aches. Took paracetamol and got relief. But at morning again i am having body aches, feverish and injection site pain. Is it normal to have this kind of symptoms after vaccination. What precautions to be taken post vaccination side effects.
