A contactable nurse (patient) reported that a female patient of unspecified age (reported as 57 with units unknown) received the second dose of BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, solution for injection), via unspecified route of administration on 27Jan2021 13:00 at a single dose for COVID-19 immunization. Medical history included at the age menopause. Concomitant medications were not reported. The patient previously took levothyroxine for thyroid disease; and hydroxychloroquine (PLAQUENIL) she was taking this because she has a connective tissue disease. The patient previously received the first dose of BNT162B2 on 06Jan2021 for COVID-19 immunization and became light headed. The patient received the 1st dose of Pfizer COVID vaccine on 06Jan2021, she felt fine, she only felt a little light headed but nothing significant. The patient was fine up until the second dose. On 27Jan2021, she received the Pfizer COVID vaccine 2nd dose, while being monitored, after 10 minutes, she felt light headed, her blood pressure went up to 170/90 and her heart rate (HR) was 85. She felt weird like I was going to die, they monitored the patient for another 15 minutes, her blood pressure came down to 130/74 and HR in the 70s. On the same day, she was jittery, pulse increased, blood pressure increased, dizziness and light headed. The same day she went back to work, took the second dose around 13:00 and at 17:00 of that same day she started feeling her old self. A week later the same symptoms came back. The symptoms have not gone away as of 23Feb2021. She was wondering if this was still a reaction to the vaccine. The following Wednesday, she started feeling the same way again, feeling light headed, felt foggy and just weird. She thought she wasn't going to be able to work but got through the day. From that day on, she continued to have this feeling. The patient was always light headed, dizzy, jittery, but not as bad at first, sometimes she has a headache. She was not back to my normal self.  Sometimes, she felt like she get a little hot, she was at the age of menopause, she was not sure, it has affected her GI system, she get a little cramping and have to have a bowel movement, she never felt this way before. The patient was calling to see if anyone is calling with these symptoms and to shed some light on how long these last. The patient was still feeling light headed, dizzy, jittery, head felt hazy, foggy. The patient asked if there is a registry for patients with special conditions, underlying conditions, or comorbidities who receive the COVID-19 vaccine, this would include pregnancy and lactation as well. The outcome of the events blood pressure increased/ blood pressure went up to 170/90 and pulse increased/ heart rate (HR) was 85 were recovering; events light headed / dizziness, head felt hazy, foggy/ felt foggy and just weird, and jittery were not recovered and outcome of the other events was unknown.
