On 02-May-2022, the patient experienced OESOPHAGEAL FOOD IMPACTION (had an impaction of food in my esophagus due to eosinophilic esophagitis) (seriousness criteria hospitalization and medically significant). On an unknown date, the patient experienced COVID-19 (COVID-19) (seriousness criterion medically significant) and INTERCHANGE OF VACCINE PRODUCTS (Interchange of vaccine products). The patient was treated with NIRMATRELVIR, RITONAVIR (PAXLOVID) from 21-Apr-2022 to 26-Apr-2022 for COVID-19, at an unspecified dose and frequency. At the time of the report, COVID-19 (COVID-19), OESOPHAGEAL FOOD IMPACTION (had an impaction of food in my esophagus due to eosinophilic esophagitis) and INTERCHANGE OF VACCINE PRODUCTS (Interchange of vaccine products) outcome was unknown.      DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 26-Apr-2022, SARS-CoV-2 test: negative (Negative) Negative, after testing at-home rapid.. On an unknown date, SARS-CoV-2 test: positive (Positive) Positive.     The action taken with mRNA-1273 (Moderna COVID-19 Vaccine) (Unknown) was unknown.       No concomitant medication was provided.

The outcome was reported as unknown. Oesophageal food impaction can be secondary to medical history of eosinophilic esophagitis. Current pandemia could be the confounder for Covid 19. Patient has received Full dose of Moderna followed by Pfizer booster. The benefit-risk relationship of mRNA-1273 vaccine is not affected by this report.; Sender's Comments: This spontaneous case concerns a 41-year-old male patient with relevant medical history of Eosinophilic esophagitis and interchange of vaccine products, who experienced the unexpected serious (hospitalization) events Oesophageal food impaction and Covid- 19 (AESI), after receiving a dose of mRNA-1273 vaccine (date unspecified) and 177 days after receiving a dose of TOZINAMERAN - PFIZER BIONTECH COVID-19 VACCINE (received as booster).
