heavy headache; 101.7 fever; Muscles were burning, exactly like when she had COVID/muscle aches/Whole muscle ached and could barely move from the pain; back heavy; could not move; has no strength; can barely walk; She was sick from getting the shot; she got so sick, it looked like COVID started all over again; felt a little bit dizzy; chills; tired; This is a spontaneous report from a contactable consumer (patient). A 54-years-old female patient received BNT162B2 (PFIZER-BIONTECH COVID-19 VACCINE, Solution for injection), dose 1 via an unspecified route of administration, administered in the right arm on 29Mar2021 at 16:45 (Batch/Lot number was not reported) as 1ST DOSE, SINGLE DOSE for COVID-19 immunisation. Medical history included COVID-19 from Dec2020 to an unknown date. The patient's concomitant medications were not reported. The patient wanted to know if she should get the second shot. She previously had COVID by the end of December. She was really sick with COVID, so then she signed up for the vaccination, and had the first dose last Monday, 29Mar2021 at 4:45PM, and then around 6:00PM, she felt a little bit dizzy, she exercised herself and went to bed. Dizziness started on 29Mar2021 and ended after she worked out. The patient stated she felt better from like the bloodstream from the workout, that helped. The patient said it ended around 7:00PM that day. In the morning (30Mar2021) around 5:00AM, her whole muscles ached, and she could barely move from the pain. It was reported that she got so sick from getting the shot, it looked like COVID started all over again, it was that heavy. Her back felt heavy, she could not move, her muscles were burning, exactly like when she had COVID. She had a heavy headache that she had to take a drug; normally, she never takes drugs, she reacts very fast. On 30Mar2021 evening, it was unbearable at 9:00PM, so she took Diclofenac, the pill form of Voltaren and that helped and one hour later at 10:00PM, she got rid of the headaches and got rid of the 101.7 fever. With the fever, she took it an hour ago, it was 98, which is higher than normal. Her temperature is always 97.3, so it's a little bit higher than normal. The patient said she still has no strength, and she can barely walk which started on 30Mar2021 and ongoing. She has been bad the whole time, but it has improved. She said she could barely open her eyes and she could not hold the phone the day before, but that day (31Mar2021), she can hold the phone with Pfizer. In Mar2021, the patient had chills and felt tired. She was thinking she should report this to Pfizer Drug Safety. She stated the CDC recommended to go for the vaccination 10 days after having COVID, and it's been three months. She said that she is still in bed that day (31Mar2021), she cannot walk. She described the side effects with the first dose of the vaccine as severe. Also, she was very sick with Covid by the end of December. She said she is a vaccine promoter, she is really standing behind it and she is the only one who got sick, not her friends or anybody else. The patient stated she doesn't have a doctor, and this is the first time she was really sick since December. The patient verified that she is speaking of the Pfizer BioNtech Covid Vaccine. The patient also believed that this reaction came because she was so sick with COVID in December. She stated she already had the antibodies and thinks she was too early for the vaccination. She was unsure if she wanted to proceed with the second dose of the Covid vaccine as she had a prior Covid infection in Dec2020. She said nobody can tell her, the second vaccination was on 19Apr2021, exactly three weeks, and she was asking what she should do. She would like to know what the second dose of the Covid vaccine does. She has talked to doctors and they don't really know. She asked whom she could ask, and what they would recommend on what she's doing with the second one. She said nobody can tell her, and the CDC Broward told her she should call 911 and she said absolutely not, she is not going to the hospital, she has never been and she's not going, and nobody can answer her. She does not believe the CDCs recommendation to receive the Covid vaccine 10 days after a person tests negative is a good idea. She said the doctor has no idea, new to the whole thing and one doctor said that he's never had any patient who had gotten sick after the first dose, he did not see that before, and this was the first time. She said she would love to talk to someone in research or something who would say yes, she can go, or would strongly recommend going. She said that at the very end, she makes the decision for herself, she would just like to hear from somebody who knows what they are talking about. No relevant tests were done.
