Reply to comment by UrbanFootprint in SARS-CoV2 enters the brain through the olfactory nerve in rhesus monkeys, causing neuroinflammation. The virus spread further into the brain in aging animals. by andyhfell

I'd assume it's less a question of easing the immune response, as more about healing the damage that virus and immune response have dealt.

Typically, viruses infect cells, and the immune system identifies those cells and kills them before they can produce more virus.

I didn't look into the background of this, but there's certainly a possibility that not all of the damage is always reversible.
