Symptoms: Fainting, Unconciouness (repeatedly), Profusive Sweating, Low Blood Pressure (60 over unknown number), Nausea, Dizziness, Unable to stabilize quickly, not able to get an IV, extreme thirst  Signs: Immediately felt unwell within 5 minutes of the vaccine.  Time Course: Injection (1st dose - Pfizer) at 4:00pm. Adverse Reaction at 4:05/4:10 (est.) Released at 5:00pm (est.)  Description of Incident:  On March 8th, at 4:00 pm, I received my first dose of the covid vaccine. Within 5 to 7 minutes, I felt unwell while sitting in the waiting area. I walked towards a worker to inform them that I was feeling unwell and that I was going to pass out. I became unresponsive and laid on the ground. My husband was with me at the time. I was unconscious for a bit and when I regained consciousness, my legs were being raised. I regained consciousness and was able to recall my name, DOB, and address. After I was done recalling my information, I began to lose consciousness again. They brought a wheelchair and took me to the medical room. As I moved from the wheelchair to the bed, I began to lose consciousness again. They told me to lay down. I overheard a woman ask my husband if I had diabetes or heart problems. He answered ?No.?. She explained to him that my body did not know how to accept the vaccine and was trying to regulate back to normal. She explained that my body was going through ?homeostasis? (?). While I laid on the bed, some workers took my blood pressure and tried to start an IV. One of them made a comment and said I was extremely dehydrated. This was odd to hear because I normally drink 3 to 4 liters of water daily. During this entire medical event, I felt the water pushing out through my pores. I was drenched in sweat. He tried to start an IV on my left arm and was unsuccessful. He tried to start an IV on my right hand, which was also unsuccessful. He stated they were unable to start IV liquids because my veins kept popping/collapsing. My blood pressure was reading 60. They checked it again, still at 60. I laid in the bed and basically waited it out. After a few minutes, they checked my blood pressure at it was at 120. They said that was good and I was good to go. No report was given to me nor my husband about the event that occurred. Even after they agreed to let me use a wheelchair (due to feeling weak), one was not provided to me. They basically stated that I was ?good to go?, after doing a series of hand squeezes and walking a few steps upright. I am currently trying to obtain a copy of the report I saw the gentleman fill out at the time. I was given Zofran to help with my nausea, it was placed under my tongue. After going home, I felt weak, tired and somewhat lightheaded. My husband drove me home and I got some rest. I set an appointment with my doctor on Friday March 12th to determine what happened to me during my vaccine and to record the incident. After describing the incident, she determined that it was anaphylaxis. She recommended for me not to get my second dose due to the anaphylactic shock I experienced with the first dose. She was shocked to learn that they did not transport me to the hospital or provided an Epi Pen injection.  When asked why I didn?t drive myself to the hospital, I let her know that they told me I was ?good?. They did not explain what had occurred to me, no mention of anaphylaxis was explained. I was not aware that is what had occurred. The incident occurred from 4:00pm (injection time) to 5:00pm (left location).
