Hello Doctor. I recovered from covid on 5th May 2021. I took my first dose of covidshield on 2nd August 2021. After 5 -7 mins of taking the vaccine suddenly I began sweating profusely, short of breath, dizziness, and sudden blackout. I was sitting on a chair at that time. After that I sat on the floor .. though I didn't need any help all of these dizziness blackout went away after about 1 min and I felt okay after that. I didn't have any anxiety related problems that day or any fear of needles, so I don't know why this happened. Though I took the vaccine with an empty stomach. My second dose is from 25th October to 22nd November. Should I take it? Any precautions that I need to take before that? Please help me Thank you!
