The human immune response to COVID-19 involves both innate and adaptive pathways
Evidence robustly supports that the human immune response to COVID-19 recruits both the innate and adaptive branches of the immune system.
The claim is a specific, well-established empirical statement about viral immunology that passes Step 0. Multiple retrieved papers explicitly discuss the involvement of both innate and adaptive immune mechanisms in response to SARS-CoV-2 infection and vaccination. No papers refute the claim.

The paper outlines the engagement of both innate (macrophages, NK cells) and adaptive (CD8+ T cells, B cells) immune cells in response to SARS-CoV-2 infection.
