On 05-Feb-2021, received second dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) dosage was changed to 1 dosage form. On an unknown date, the patient received third dose of mRNA-1273 (Moderna COVID-19 Vaccine) (unknown route) 1 dosage form. In July 2022, the patient experienced COVID-19 (Had Covid 3 weeks ago) and DRUG INEFFECTIVE (Lack of drug effect). The patient was treated with NIRMATRELVIR, RITONAVIR (PAXLOVID) for COVID-19, at an unspecified dose and frequency. In August 2022, COVID-19 (Had Covid 3 weeks ago) had resolved.
