The overarching, nagging concern: “They don’t know what they don’t know,” said a source close to the Biden Covid-19 team…

One source familiar with the Biden effort acknowledged a major gap the incoming team will have to confront is that there is currently no effective and trustworthy line of communication between states and the federal government.

Ramping up federal involvement in coronavirus testing and vaccine distribution starts with building up communications with each state to better understand their infrastructure and supply challenges, something that’s expected to be a focus in the early days of Biden’s presidency.

States are clamoring for the federal government to release larger batches of vaccine. But it’s still not clear if there will be enough vaccine available to drastically speed up the pace at which they can be distributed and administered.
