Good news keeps coming. Critically important that states and federal gov't use these next few weeks to prepare their vaccine administration sites/programs (and scheduling systems, IT, etc.) to rapidly scale up to handle this expected surge in supply. https://t.co/WxeRLTQqY4

Pfizer, Moderna promising many more vaccine doses for the US in the coming weeks after solving some manufacturing issues.

Pfizer says 120 million, Moderna 100 million doses, by the end of March, which would imply a major acceleration from current supply.https://t.co/ijkDRPmJKV
