Daily Monitor Sunday May 02 2021 Covid-19 Pfizer vaccine. The effects of these vaccines have nearly been proven to affect people differently. PHOTO/NET Summary Advertisement Three weeks ago, I took the first dose of the Pfizer vaccine shot. The next day I felt pain in my whole body and was a bit feverish, at the same time my husband took the same shot, but he had almost no apparent reactions or symptoms related to the vaccine. A couple of days ago, I took the second dose of the vaccine, and I have to say that this time it completely knocked me down. I spent the first night with a high fever, shivers, and my husband said I was hallucinating all night.
