severe chills; Shaking; flu-like symptoms; a lot of weakness; This is a spontaneous report received from contactable reporter(s) (Consumer or other non HCP). The reporter is the patient.  A 74 year-old male patient received bnt162b2 (BNT162B2), administered in arm right, administration date 12Mar2021 09:30 (Lot number: EN6204, Expiration Date: Jun2021) at the age of 74 years as dose, 2 single for covid-19 immunisation. The patient's relevant medical history and concomitant medications were not reported. Vaccination history included: Bnt162b2 (Dose number=1), administration date: 18Feb2021, when the patient was 74 years old, for COVID-19 immunisation. The following information was reported: CHILLS (non-serious), outcome "unknown", described as "severe chills"; TREMOR (non-serious), outcome "unknown", described as "Shaking"; INFLUENZA LIKE ILLNESS (non-serious), outcome "unknown", described as "flu-like symptoms"; ASTHENIA (non-serious), outcome "unknown", described as "a lot of weakness". Relevant laboratory tests and procedures are available in the appropriate section.  Additional information: Patient says he had no problems with the second vaccine all day on 12Mar2021 until 10:30 that night. Then, all of the sudden, at 10:30, he got the chills like one would not believe. It was just severe chills. The worst part is that he started shaking- not shivering or quivering, literally shaking. He shook from 10:30 until 3:30 in the morning violently. He had chills and flu like symptoms, and a lot of weakness for 4 days. After the 4th day, he started to try to get back to doing things, but that shaking- he cannot describe the horribleness of it. The shaking has not gone away, the shaking has remained. His motor skills are very bad- he cannot sign his name. Today, he wanted to send a sympathy card out and he was barely able to print in the sympathy card or print on the envelope. He says the shaking is not visible anymore, but the minute he puts a pen in his hand and tries to use the pen, or a wrench, or a screwdriver as he tries to put the screwdriver on the screw, all of the sudden, he can't do that. He has never had serious issues with this before especially with signing his name. He can't even fill a check out. He says many years ago, he did have a reaction to a penicillin shot. He clarifies he think this shot gave him the hives, it must have been 30 years at least. Patient didn't receive any other vaccine within 4 weeks. He never took his blood pressure or anything. To the best of his knowledge he never had any temperature. He took his temperature a couple of times because he thought he had a temperature, but when he checked his thermometer, his temperature was something like 97.5 or 98.3. He says his temperature is usually below 98.5, its a little lower than what its supposed be, it has always has been that way for him.  He said he did call his doctor and talked to his nurse, and he described everything to them. They just said the best thing to do is just wait a while and see what happens. After he tried doing that sympathy card this morning, he told himself he had to let Pfizer know how serious this is- its the shaking and the motor skills that are so serious.  No follow-up attempts are possible. No further information is expected.
