Great post and points....I agree. As you allude to, I think we will also be seeing annual covid shots with varied effectiveness due to mutation....following the receipt of a safe, effective one.....whenever that day comes.
I still think by spring 2021 and the GSE PO, we will at the very least have achieved some semblance of herd immunity, although I think we may be living with wearing masks in public for the foreseeable future, a la Asia.
