Treatment of Severe Pneumonia due to COVID-19 with Peginterferon alfa 2a

Abstract The outbreak of the new coronavirus disease 2019 (COVID-19) has spread rapidly worldwide. Until now, no definite effective treatment has been identified. We reported 3 patients with severe COVID-19 treated with pegylated interferon alfa 2a with satisfactory recovery. Based on these observations, randomized studies with interferons should be considered in deteriorating patients infected with COVID-19.
