A 39-years-old patient of an unspecified gender received bnt162b2 (Pfizer-BioNTech COVID-19 Vaccine, Solution for injection), dose 2 via an unspecified route of administration, administered in (Deltoid Left) left shoulder on 18Jun2021 (at the age of 39-years-old) (Batch/Lot Number: EW0181) as DOSE 2, SINGLE for covid-19 immunisation.  The patient medical history and concomitant medications were not reported. Historical vaccine included first dose of BNT162B2 (Lot/batch number: EW0167) on 08May2021 for COVID-19 immunization. The patient experienced ended up developing a fever of about 103 on 18Jun2021. So patient got like, it just hit him like a ton of bricks that day but unfortunately lasted for like a couple of days and then it started to like taper off after like, Patient think Monday and Tuesday but patient also experience lot of tiredness, big big headache, muscle pain, chills, joint pain, fever like patient said, just felling unwell. Patient was just like, feel like patient just was overwhelmed and then patient just got like really super weak and It couldn't even get up at that time when it occurred, when it started like patient guess having the effect on, it was early in the morning the next day. So patient just momentarily, did also have difficulty breathing but it kind of like wore away because took some pill (treatment) for fever and stuff. Also, patient had a fast heartbeat too, dizziness, weakness. So that's pretty much most of the symptoms that patient had and cloudiness like confusion, notice that stays until about almost 2 weeks after. On Thursday to Friday of 2 weeks after the shot that had took in, that's when it started kind off to wear away a little bit, but patient still kind of have doubts and symptoms of that like fogginess and confusion. But it's just not as bad but sometimes patient do get that, so patient hoping that it's not like permanent and that's not long term hopefully because really got it. Actually, it was about a week and a half patient got really bad, patient still was in this hazy state mentally and that pretty much sums it up of all the effect that have for the shot. Because patient experienced maybe just a little bit maybe like a week on the first one but then the second one like really hit him/her hard like a ton of bricks like said. Patient has no recent lab test, it had been more than over a year. Patient took treatment of regular over the counter medication. Patient had not received any vaccination 4 weeks prior to COVID 19 Vaccine. The patient wants to make sure that to inform that patient did have the side effects. The patient did not want to delay any further because it was already been quite a bit, a couple of weeks after it happened. The only like said was the confusion that still kind of lingered within like one, two weeks but it seems like haziness, kind of slowly drifting away and don't know have had like some kind of doubts of loss of energy. Don't know it's been kind of sporadic. Outcome of the event cloudiness like confusion was not recovered. Outcome of the other events was unknown.  Information on Lot/Batch number was available. Additional information has been requested.
