We show that neutralizing autoantibodies to type I IFNs underlie a third of the life-threatening adverse reactions to yellow fever virus live-attenuated virus (YFV 17D): https://rupress.org/jem/article/218/4/e20202486/211761/Auto-antibodies-to-type-I-IFNs-can-underlie
We also report a patient with YFV 17D disease due to inherited IFNAR2 deficiency, consistent with our previous description of a patient with inherited IFNAR1 deficiency: https://rupress.org/jem/article/216/9/2057/120723/Inherited-IFNAR1-deficiency-in-otherwise-healthy
These studies indicate that at least half of the rare but devastating cases of YFV 17D disease are due to inborn errors of type I IFN immunity or their autoimmune phenocopy.
They also show that neutralizing autoantibodies to type I IFN can cause not only critical COVID-19 pneumonia ( https://science.sciencemag.org/content/370/6515/eabd4585.long), but also another viral disease. Importantly, the patients developed YFV 17D disease within a few days post vaccination.
This provides further evidence that these autoantibodies in patients with COVID-19 are not a consequence of SARS-CoV-2 infection, but pre-exist infection and are actually causal of critical COVID-19 pneumonia.
