Write-up: About 18 hours after the vaccine was given, the patient developed chest pain. The chest pain progress over about 24 hours to 9/10. He presented to the ER where he was found to have elevated troponin (up to 15) and ST changes on EKG. Echo was normal x2. He was treated for myopericarditis with NSAIDs and colchicine. He quickly improved. No clear etiology of his myopericarditis was identified, raising suspicion that it may have been an adverse reaction to the vaccine.

Write-up: Patient is a 16yo girl admitted on 5/19 with sepsis secondary to myocarditis and pneumonia, s/p IVIG, after presenting with fever, myalgia, sore throat, hypotension, elevated troponin, elevated CRP, and leukocytosis with left shift. Sore throat has been present for about a week and fevers began on 5/17 with a Tmax of 103. On 5/18, she began developing shortness of breath and upon evaluation by the PCP on 5/19, she was admitted. During initial workup on 5/19 upon admission, hospitalist was high concerned as she developed hypotension of 91/48 on 5/20 at 08:35am. CT of chest on 5/20 showed patchy consolidation of the posterior lower lobes bilaterally. At that point, I was contacted and recommended broadening regimen to clindamycin , ceftriaxone, and azithromycin. Upon transfer to Hospital, further serologies were collected which showed leukocytosis with left shift, highly elevated CRP, elevated troponin, elevated IL-6, elevated ferritin, negative Covid abs test, negative RVP, and negative Covid PCR. IVIG (2grams/kg) started on 5/20 at 22:57. Cardio and ID on board and all regular myocarditis infectious workup has been collected. ID consulted for workup and management. Of note, patient received the Covid vaccine on 5/1/21
