A 63-years-old male patient received first dose of bnt162b2 (Solution injection, Batch/Lot Number: EN6204, Expiration date: UNKNOWN), via an unspecified route of administration, administered in Arm Right on 11Mar2021 at 12:15 as single dose (at the age of 63-years-old) for covid-19 immunisation. Medical history included ongoing arthritis. He may have to have a knee replacement because the arthritis is pretty bad in his right knee and it swells up from time to time. Plus they gave him a brace that goes over his knee when he stands up so he has a lot of support. There were no concomitant medications. Patient did not receive any prior vaccinations within 4 weeks. Patient stated that he received the first injection and it scared him. He sat there for 15 minutes after the injection and it was fine. He had to drop something off at someone's house. Then when he was there he got sleepy and he said he had to go home to take a nap. He laid down to take a nap then all of a sudden he felt really really sleepy. All of a sudden, his right leg all the way from his hip to his knee, he does have arthritis in his knee, they are talking about doing a knee replacement and he doesn't know if that plays a role in this or not. However, all of a sudden it started hurting to the point where he could not get comfortable. He tried everything, all positioning, anything he could do, for about 30 mins at least, maybe longer, it was just constant pain like something inside was trying to get out. It was a weird feeling. He questioned if it could have happened because he has trouble with knee. He feels awake today, it hit him yesterday, he felt really groggy, he started feeling kind of groggy and started yawning. By the time he made it home then he was ready to lay down. However, the leg hadn't started hurting. When he did finally lay down, his leg really set in. It's not hurting like it did yesterday. Yesterday was tremendous hurt. It's sore today. When she gave him the shot it bled and she got some blood on his shirt and he isn't blaming her but he was surprised it bled like that. She put a band aid on it and got the bleeding stopped. The patient stated he experienced fatigue "like I was sleepy and wanted to lay down," pain on his right side (the side he received his injection, in his hip down to his knee. Patient stated, "it was not mild pain it was like someone was inside of my leg trying to beat out. Patient thought about calling someone to take him to the hospital."
