Good News – Perhaps. Probably.

CDC Asks States to Plan for Potential Vaccine Distribution in Late October (NPR)

Even though this has been walked back a little since the initial announcement, even if a covid vaccine is available in say late November, that's still faster than anyone could reasonably have expected just six months ago.

This is encouraging, so long as the antibody-dependent enhancement (ADE) question is addressed.  You can read up on ADE here (TLDR: fading/low antibody levels can backfire and actually assist viruses in attacking cells).  Some are saying Yikes!, while others are saying this problem is unlikely, but we're watching out for it anyway.

Either way, I figure there are the Phase III trials plus several million healthcare workers and first responders in line ahead of the rest of us ordinary folks.  Any questions will be long answered before we get to line up.  But, pretty much... yeah, sign me up already.
