No prior vaccination was taken within 4 weeks. The patient stated that her last vaccine she got as child. The patient believed she took her blood pressure medication that morning and that she wasn't told not to take anything. It was reported that on 05Jun2021, within 15 minutes after getting the vaccine the patient started to feel the dizziness. It wasn't severe. She felt a little week from it and those didn't start until probably 30 minutes after the injection and lasted for about 1 hour. The patient did not eat that morning. She did get up and before she left and she grabbed something to eat and drink (had a fruit smoothie). The patient took a car service there. The patient still felt it but not to a great degree. The patient reported that she sat there at the site for about 15-20 minutes and as she went to get up and started walking toward the door, she did feel slightly dizzy. The patient was asking if this was common or not. She stated it was not really dizzy, like faint dizzy, but she felt dizzy and weak. She stated that about 2 hours after the vaccine she felt tiredness and that lasted most of the afternoon for a good couple of hours and nothing else. The patient kept moving and pushing and stopped within a half hour after she got home and in the next hour, she started to feel tired. She was moving around getting things done (she was doing renovations at her house) and hour and half she got home she started to feel a little tired and sat down. In the evening hours she was feeling ok, not feeling as tired, feeling lethargic. It just lasted that Saturday. The patient stated weakness wasn't as bad as the feeling tired. On 06Jun2021, Sunday morning the patient had soreness in her left arm where the vaccine was administered. Most of the day she felt soreness no dizziness and not feeling tired. Today she was feeling fine and back to normal. Maybe a little tenderness at the site. The patient considered dizziness and weakness as severe allergic reaction and not just a side effect.
