IL-17A is a pro-inflammatory cytokine mainly produced by Th17 cells, but also by innate and other adaptive immune cell components such as natural killer T cells, macrophages, neutrophils, CD8+ T cells, γδ T cells and innate lymphoid cells [supplementary material.
Th17 responses in patients with SARS-CoV-2. They found that peripheral blood cells from patients with severe COVID-19 infection had strikingly high numbers of circulating Th17 cells which were associated with a “cytokine storm” including IL-1β, IL-2, IL-7, IL-10, IL-17, G-CSF, interferon γ-induced protein 10 (IP-10), MCP-1, macrophage inflammatory proteins (MIPs) and TNF-α. As a result of this hyper-inflammatory state, the authors suggested the use of Fedratinib, a Janus kinase 2 (JAK2) small molecule inhibitor which is involved in the suppression of signal transducer and activator of transcription 3 (STAT3), as a potential therapeutic agent for patients with elevated Th17 (but also Th1) type immune profiles

Many studies showed the elevated level of IL-17 in Severe cases of COVID-19 whose addmitted to intensive care unit. If you proposed to use IL-17 blockers as a strategy for treatment of CIVID-19 this may let the patients vulnerable for other intracellular infection.
