hard to hear at times; horrible pain from head to toe; couldn't see anything; couldn't breathe at all; face turned green; fever; aching in her legs; extreme exhaustion; blacking out; diarrhea; sweating; unable to talk; This is a spontaneous report from a contactable consumer. A 30-year-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE), dose 1 via an unspecified route of administration, administered in Arm Left on 06Apr2021 12:00 (Batch/Lot Number: EW0150) as 1st dose, single, at the age of 30-years-old for COVID-19 immunization. The patient had no medical/family history and concomitant medications. The patient went to go get her second shot of Pfizer covid vaccine but they wouldn't give it to her based on her reactions to the first dose. They said there was a chance of anaphylaxis reaction to the second shot. The patient reported blacking out, diarrhea, sweating and unable to talk. She consulted with her healthcare professional regarding whether to get the second shot and they didn't know. She asked if her reactions were normal. She doesn't know what to do whether to get a second shot given her reaction. It was mentioned that the patient was hard to hear at times. She got the vaccine on 06Apr2021 around noon and she was fine until around 3:30 am. She woke up in horrible pain from head to toe, she thought maybe she just needed to pee, she didn't know what was going on. She stood up and she blacked out like she was about to faint. She couldn't see anything, like it was completely black. She got to bathroom and she couldn't breathe at all, she couldn't talk. She thought she needs to go to the hospital, but she couldn't talk. Her face turned green, she had diarrhea, she was like dripping wet. At this point, she could sort of breathe. She felt like she was being held under water, still dripping sweat. She has recovered completely from these symptoms. The severity of symptoms was so severe she doesn't know if she had a fever at the same time, it was hard to tell. With the breathing part, she was so freaked out by that, so it's hard to know for sure, maybe yes. She may have had a low fever. She had a fever that night to the point where she was dripping on the floor. She has aching in her legs. She went to the doctor thinking she had Lyme disease, which she doesn't. Since that vaccine, she's had very, somewhat severe leg aches and extreme exhaustion like all the time. she can hardly go to work sometimes. Everybody has days they are tired, but this was different. She had to come home at 2pm and lay down for like five hours. She stated it was persisting. She had a blood test recently and everything came back perfect on 26Apr2021. She thought she had Lyme disease because of all the symptoms she was having, and it all came back negative. She didn't exactly get turned away. They said they didn't feel comfortable giving her the second dose of vaccine. The patient stated if a nurse tells her they don't feel comfortable, she wouldn't feel comfortable until she speaks to Pfizer. The nurse told her she had to go to an allergist and rheumatologist. The nurse said the same thing, the nurse told her that she should have gone to the hospital, but she wasn't thinking at that moment. She was just at a loss of what to do. That day at the hospital, they were scared with the second vaccine that she could go into anaphylaxis and she's not sure what to do. The patient had no other vaccines administered on the same date of Pfizer suspect and no other vaccinations within 4 weeks. The event hard to hear at times started on an unknown date while other events started on 07Apr2021 and ended the same day. The outcome of the events aching in her legs and exhaustion was not recovered, hard to hear at times was unknown while for other events was recovered. The events "she blacked out, like she was about to faint" was assessed as serious medically significant.  No follow-up attempts are needed. No further information expected.
