Write-up: myocarditis with PR segment depression and a Troponin of 9000; Chest pain; This is a spontaneous report from a contactable physician. A 16-year-old male patient received the second dose of BNT162B2 (PFIZER COVID-19 VACCINE, lot number: EW0168), at the age of 16 years old, intramuscularly in right arm on 29May2021 14:00 at single dose for covid-19 immunisation. Medical history included allergies to pollen. The patient was not diagnosed with covid-19 prior to vaccination. The patient did not receive any other vaccines within 4 weeks and any other medications within 2 weeks prior to vaccination. The patient previously received the first dose of BNT162B2 (lot number: EW0172), at the age of 16 years old, intramuscularly in right arm on 08May2021 12:00 at single dose for covid-19 immunisation. Shortly after the patient began experiencing a cough which has persisted until currently presentation. The patient received his second dose on 29May2021 14:00 and developed chest pain on 30May2021. Subsequently the patient experienced myocarditis with PR segment depression and a troponin of 9000. The patient was admitted to the hospital for 2 days. The patient underwent lab tests and procedures which included PR segment depression and troponin 9000 on 30May2021, SARS-CoV-2 by nucleic acid amplification (NAA) test (nasal swab) negative on 01Jun2021. The patient received treatment with scheduled non-steroidal anti-inflammatory drugs (NSAIDs) and at present he had improvement in symptoms and troponins. The outcome of events was recovering. No follow-up attempts are needed. No further information is expected.; Sender''s Comments: Based on available information, a possible contributory role of the subject product, BNT162B2 vaccine, cannot be excluded for the reported events of myocarditis and chest pain. There is limited information provided in this report. This case will be reassessed once additional information is available. The impact of this report on the benefit/risk profile of the Pfizer product is evaluated as part of Pfizer procedures for safety evaluation, including the review and analysis of aggregate data for adverse events. Any safety concern identified as part of this review, as well as any appropriate action in response, will be promptly notified to Regulatory Authorities, Ethics Committees and Investigators, as appropriate.

CDC Split Type:

Write-up: This is a 15 year old male without PMHx who presents with chest pain for one day after having Pfizer COVID vaccine 2-3 days prior. As per father patient had first dose without any sx except mild soreness on the site of injection. On 6/9/21 he received the second shot of Pfizer vaccine. That day he only fell mild pain on site of infection only. Next day he suffered from chills, HA, and fever. He took Tylenol for it. The day prior admission he had a mild headache and pain on the middle of the chest, dull, not radiating, and on/off. There was one episode of emesis after dinner and after taking TUMS he went to sleep. The parents check on him through the night and upon waking up he complaint still with chest pain, now increased and radiating to left side of the chest. The parents decided to bring him to ED for evaluation where he was found to have elevated troponins and he was admitted for myocarditis likely secondary to the Pfizer vaccine. His troponins were monitored q8hrs and he was started on Toradol q6hrs. See EKG and Echo results below. Due to increasing troponins 6/13, he was given IVIG with resulting improvement. At this time, we are still monitoring his troponin inpatient with plan for potential cardiac MRI. He will be discharged home on Ibuprofen 600mg TID and follow up with cardiology with exercise restriction likely for a few months, tbd by outpatient cardiology follow up.
