The action taken for aspirin [acetylsalicylic acid] was unknown.  Additional information: Patient did not believe that took prior vaccinations. Patient got some problem since he got that third shot (Clarified as COVID-19 vaccine) from Pfizer. Patient have got the first two shots and had no side effects whatsoever on either one of those shots and then that was time period and quite long after that and then he got the third shot. The reason patient got the first two from (name withheld) because it was not readily available. The shots they were in very short supply that's why he went to the (name withheld). Third shot he got from [Facility name withheld]. Ever since then, patient have not felt the same. Patient energy level was gone to put and don't have the strength he used to have. His equilibrium was kind of not good and have fallen twice since he got that shot. He never used to fall at all. He was in pretty good shape even for age. Patient have lot of aches and pains specially in legs and feet are all tingling all the time and the tingling, He don't know, get that in his feet. He was sitting here right now he got, but he don't feel steady when he was walking all the times on feet. That's how he fell. Patient never had this before and before the first two shots, never had any of this. This all happened after the third shot and muscle pain, like the biggest thing is well fatigue. Patient don't have the stamina that he used to have, that's the biggest thing. He get very winded going around the house or anything like that. He have to take a break and was never like that before. He don't know what's going on here. Patient's memory was kind of going haywire too. He don't and can't remember things like he used to. Reported that when get up in the morning, He had breakfast and if he take a 325 milligrams Aspirin, all the tingling almost goes away, almost all of that and it lasts for pretty much a day. He think its working so on, but If he don't take it, like patient haven't taken it today (at the time of report) and his feet is tingling like crazy right now. But, why would the aspirin, other than it thins your blood out and he think that's what's happening and it helps the problem. It kind of relieve some of the problem, not all of it. The biggest and the other concern he got is, he just don't feel secured while he was walking on feet. That's the biggest problem. Patient have been taking aspirin, lot of times he tried taking lesser amounts of baby Aspirin cause it's like half of the milligrams and it's not good to be taken all the time.   The information on the batch/lot number for BNT162b2, BNT162b2 omi ba.4-5 has been requested and will be submitted if and when received.
