she felt her scalp itch like there were bugs on it/Scalp was just itching like crazy; headache; muscle and joint pains; muscle and joint pains; chills; temperature was 99.8 so the next time I took it and it was 100.8; felt lethargic; didn't get sleep that much; my throat closing up; This is a spontaneous report from a contactable consumer, the patient herself. An 81-year-old female patient received second dose of bnt162b2 (PFIZER-BIONTECH COVID-19 VACCINE, formulation: Solution for injection, Lot number: ER8732; Expiration Date: 31Jul2021), via an unspecified route of administration, on 26Mar2021 (age at vaccination: 81-year-old), as single dose for COVID-19 immunization. Medical history was reported as none (not heard anything from anybody). There were no concomitant medications; she did not take any medications because she did not know if it was permissible. The patient previously received first dose of bnt162b2 (Lot Number: EN6198 and Expiry: 30Jun2021) on 25Feb2021 and she did not experience side effects from that dose. The patient reported that, yesterday (26Mar2021) was fine, it did not hurt the arm and everything, however, at 2 o'clock this morning, on 27Mar2021, she felt her scalp itch like there were bugs on it. Her scalp was just itching like crazy, and it would not stop itching so she just had to run her fingers through there, got a little bit of alcohol and just kind of rubbed it in there but it was just something under the skin. She then experienced headache, muscle and joint pains, chills, and a fever. She took her temperature, and it was 99.8 so the next time she took it, and it was 100.8, but since then it had got down to 99.7, so she still felt like she had fever. She had a feeling that she was slow and just did not want to do anything and that was how she left the day because she did not know whether she was going to react to it or not but there was no swelling around the injection site, no nausea, did not have swollen lymph gland, heart beat was not fast, did not have a bad rash, dizziness (not clarified further if had dizziness or not), no weakness, maybe weakness from no sleep because she hardly had any sleep and also felt lethargic. She did not see any swelling of face or throat, so she was mainly worried about her throat, maybe her throat closing up. She mentioned that these not concerned her and as long as she could swallow, she did not panic and could bear it. She said that she had been through so many shots in her life and she never had a reaction like that before so she did not think she would be required to go to the emergency room or anything like that because she just did not feel, but she said yes that was important that she take care of this, but it was not emergency in her book. She was so hungry, she just had a muffin and was not vomiting yet, she did not think anything would happen like that, as she did not think it was serious. Reportedly, she did not throw up and she felt like it would be more bearable for her to have food in her belly. She told that, she purposely did not have any lab test done because she knew this COVID was coming up and she had to have 3 boosters that she needed to take, but she was going to take them 2 weeks after. She also reported that, she did not take corrective treatment for fever and itchy scalp, as someone told her not to take anything, Tylenol or an Aspirin, so she did not. The outcome for the events: fever and itchy scalp was recovering (It was improved throughout the day and she walked around the house a lot just, because she exercises), and the outcome was unknown for the rest of the events.  No follow-up attempts are possible. No further information is expected.
