At earliest, the top infectious disease official in the United States says a coronavirus vaccine may be deployable at scale by the very tail end of 2020. If everything goes right, and the vaccine works. And not for everybody, at least not until early 2021. Again, this is at the earliest if everything goes exactly right. In unrelated news, CES thinks it can hold a giant convention next January.

CES brings well over a hundred thousand people down on the city of Las Vegas via airplanes from every corner of the globe. CES is known for its extreme human density, not just in the convention center, but in hotels, restaurants, public transit (yes, people use the monorail at CES), event venues, taxis, buses, clubs, and bars.
