Interferon is a cytokine that is produced by our own bodies as part of the immune response against an invading virus or bacteria.
It is produced at the end of an attack, and helps the body reduce its own immune reaction and the severity of the inflammation caused. Call it a modulator if you will.
It is currently used to treat multiple sclerosis.
As some Covid-19 patients have a cytokine storm that causes their lungs to fill with fluid, requiring them to be ventilated, a drug like interferon-beta can help to “calm” this storm and prevent the need for ventilation.
