Relevant medical history included: "Chronic Kidney Disease" (ongoing), notes: he has kidney issues. The patient's concomitant medications were not reported. Vaccination history included: Comirnaty (Dose: 1, felt tired for a few days), for COVID-19 immunisation, reaction(s): "tired"; Comirnaty (Dose: 2, felt tired for a few days), for COVID-19 immunisation, reaction(s): "tired"; Comirnaty (Dose: 2, to 20% and then got better/ 2nd shot to have raised his creatinine numbers 25% and he recovered from that), for COVID-19 immunisation, reaction(s): "creatinine went up". The following information was reported: IMMUNISATION (non-serious) with onset Oct2021, outcome "unknown", described as "booster"; FATIGUE (non-serious) with onset Oct2021, outcome "recovered" (Oct2021), described as "felt tired for a few days"; BLOOD CREATININE INCREASED (non-serious) with onset Oct2021, outcome "not recovered", described as "creatinine levels jumped another 20%/goes up 20% higher than baseline"; SLUGGISHNESS (non-serious) with onset Oct2021, outcome "recovered" (Oct2021), described as "sluggish".

Additional information: Clinical Course: Patient was advised by his provider to take the Pfizer COVID vaccine and he has since had dose 1, 2 and 3. Patient stated after receiving the document he "dealt with a few days, felt tired for a few days." Patient also reported that his creatinine level jumped 20-25% and took 4,5,6 weeks to go back to normal. He stated when he was reading and took the booster dose 1 week ago and now again noticed that his creatinine levels jumped another 20%. He stated that the levels came back to what it was and then jumped again during his dosing of the vaccines. He feels as though this time he will come back down as well but did not know if Pfizer had any recommendations. Patient stated that he felt okay now but for a week he was "sluggish." He was wondering why his kidney creatinine levels did that with the 2nd shot and then came back down after 6 weeks. With the 3rd booster dose he again stated it says it "goes up 20% higher than baseline" and was not sure if this was a listed side effect. After the "2nd shot" the creatinine went up to 20% and then got better, now happened 2 times where it went up. The patient did not feel any problems, he felt fine. Four days of sluggishness when he took the shot now he's fine. Patient had an elevated number when he took his blood test today. The events were reported as non-serious.  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
