Clinical narrative: felt tired for a few days; This is a spontaneous report received from a non-contactable reporter(s) (Consumer or other non HCP) from medical information team. The reporter is the patient.  A male patient received bnt162b2 (BNT162B2) (Batch/Lot number: unknown) as dose 1, single for covid-19 immunisation. Relevant medical history included: "Chronic Kidney Disease" (unspecified if ongoing). The patient's concomitant medications were not reported. The following information was reported: FATIGUE (non-serious), outcome "recovered", described as "felt tired for a few days".  Additional information: Patient had kidney issues, Chronic Kidney Disease. He was advised by his provider to take the Pfizer COVID vaccine and he has since had dose 1, 2 and 3. Patient after receiving the document he dealt with a few days, felt tired for a few days. 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 felt as though this time he will come back down as well but didn't know if Pfizer MI had any recommendations. He wanted to get better, and he did read in the paperwork from the Pfizer website that the numbers do go higher than 20% at the baseline. 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. He does not regret taking the vaccine & he hopes he gets better. He 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. It could be a good chance that it will get better like it did the 1st time. He doesn't want to panic with seeing an elevated number as he was under medical care. He wanted to know if an alternative vaccine, such as the Moderna or J&J would be better for those with renal issues. If he kept having to take it and it kept elevating his kidney levels, but he noted that it was otherwise you "die" if you have COVID with kidney issues. He felt as though he did the right thing and does not want his provider to send him for dialysis like they almost did last time due to elevated numbers, but he got better 20%. He did not felt any problems, he felt fine. Four days of sluggishness when he took the shot now, he was fine. He has an elevated number when he took blood test today. 2nd shot raised his creatinine numbers 25% and he recovered from that. The booster was received one week ago, and it went up 20% which was exactly what the paper says. He wanted to know that long does it take for the booster to get into the system and work so he can better help gauge possibly how long his concerns may be around for. He wanted to know if the booster dose is the same or if it is half the dose. The booster dose was the same vaccine that was used for the primary series  No follow-up attempts are possible; information about lot/batch number cannot be obtained. No further information is expected.
