Reporter stated the first time she went to the doctor, she took the first available appointment, so she saw a new physician and she asked for it to be recorded, but the doctor probably blew her off because she said just go get your second shot. Reporter stated she had been looking online and it said don't do it. Reporter stated she went back again to follow up with her doctor, said she said she wanted it reported and she stressed that to her so she probably did. Reporter stated her doctor is one of the head administrators and she actually had to beg to get her as her doctor, usually they just assign patients to a rotating doctor, but she got a higher up administer that also sees patients. Reporter stated after the 15 minutes they came around and asked if she is okay. Reporter stated she started to feel a little weird but she thought she was okay. Reporter stated by the time she got to her vehicle, she had extreme thirst and nausea, this was about 25 minutes after her vaccine. Reporter stated she chugged and chugged water and then it kind of went away for a good hour or 2 and then she started feeling nauseous again and drinking water and decided she needed to eat something, so she ate and then it was like after she ate, she started to get a weight on her chest so she laid down and tried to relax. Reporter stated the pressure lasted 4 hours and then all of a sudden that pressure released. Caller states her initial reaction from the shot was from 2:00pm until 9:00pm.

Reporter stated she was expecting fever, headache, aches and pains. Reporter stated she was looking at the side effects and said oh no, this is considered an allergic reaction. Reporter stated she was on the phone Monday morning to her doctor's office. Reporter stated she probably should've gone to the hospital but she was too afraid to move, she thought she needs to lay down and keep relaxed and hydrated and concentrate on breathing. Reporter stated on Monday when they called her back, she kind of had to run a bit for her phone and she almost hyperventilated, she couldn't catch her breath. Reporter stated she would not go get the second shot, she can't get the full dose. Caller states she is willing to try a lower dose. Treatment: None, Reporter stated when she talked to the doctor's office, she talked to the nurse, and she said she is not the only one calling with those same symptoms, and they should dissipate in 3-5 days. Caller states the nurse said she should have gone to the ER or the fire station to have her vitals checked. Caller states she lives near the fire station but she didn't think about it. Reporter stated she guesses everyone will make her wait until the lower dose comes out. Reporter stated the previous agent basically said the lower dose is not approved and it has never been studied in her age group. Reporter stated she is going to have to do something because she is anticipating this is not even going to go away and we'll probably be in the pandemic probably for 3 years because people won't get their shots.
