In May 2022, the patient experienced COVID-19 (Symptoms never fully disappeared, still had a cough.On 27-May-2022  Patient tested positive again, no change in symptoms). The patient was treated with NIRMATRELVIR, RITONAVIR (PAXLOVID) from 18-May-2022 to 22-May-2022 for COVID-19, at an unspecified dose and frequency and METHYLPREDNISOLONE ACETATE (METHYLPREDNISOLONE [METHYLPREDNISOLONE ACETATE]) at an unspecified dose and frequency.

DIAGNOSTIC RESULTS (normal ranges are provided in parenthesis if available): On 23-May-2022, SARS-CoV-2 test: negative (Negative) Negative. On 27-May-2022, SARS-CoV-2 test: positive (Positive) Positive.         An unspecified 'Cough suppressant/expectorant with nasal decongestant' was reported as concomitant medication which was started on 17May2022.  Patient was taking other medications/products within 2 weeks of starting COVID-19 treatment. Patient previously received a COVID-19 vaccine.  Device Date was reported as 28May2022.  Company Comment: This is a spontaneous case of interchange of vaccine products for this 33-year-old, female patient with relevant medical history of Asthma and Depression, and past drug history of administration of one dose of the Johnson & Johnson COVID-19 vaccine, who experienced the unexpected, non-serious AESI of COVID-19. The event occurred approximately 6 months after receiving a dose (second dose in COVID-19 vaccination series) of the mRNA-1273 vaccine. On an unspecified date, the patient experienced COVID-19 symptoms which included cough. She initially took an unspecified cough suppressant/expectorant with nasal decongestant. The following day, the patient took and completed a 5-day course of Paxlovid (nirmatrelvir, ritonavir) from 18May2022 to 22May2022. It was reported that after the last dose of Paxlovid, the symptoms never fully resolved and the patient still had a cough. One day after the last dose of Paxlovid, the patient also experienced moderate shortness of breath but she tested negative for SARS-CoV-2. It was reported that the symptoms continued all week. Five days after the last dose of Paxlovid, the patient tested positive for SARS-CoV-2. The patient was treated with methylprednisolone (unspecified dosage, frequency and duration). However, the event had not resolved at the time of the report. The medical history of Asthma and Depression, which are known risk factors for COVID-19, remain as confounders. The benefit-risk relationship of the mRNA-1273 vaccine is not affected by this report.; Sender's Comments: This is a spontaneous case of interchange of vaccine products for this 33-year-old, female patient with relevant medical history of Asthma and Depression, and past drug history of administration of one dose of the Johnson & Johnson COVID-19 vaccine, who experienced the unexpected, non-serious AESI of COVID-19.
