US vaccination campaign will pick up speed now that access is broadening, leaders from Operation Warp Speed, Pfizer, Moderna, McKesson and CVS Health say at a J.P. Morgan panel discussion.

Most vaccines will be distributed centrally by McKesson, but those with ultra-cold storage requirements will be shipped directly from the manufacturer to the vaccination site. Data exchange system will enable public and private databases to talk to each other and help ensure individuals receive timely revaccination with a second dose of the same vaccine regardless of location.

Even as Pfizer and Moderna says their vaccines would need to be stored at very low temperatures, CDC official urges delay on equipment acquisition.

CDC developing vaccine distribution plans with four states and one large city that will serve as a ‘foundation’ for other jurisdictions; plans include provisions for all potential vaccines, but logistics will vary depending on product, especially given the cold chain issues associated with mRNA vaccines from Pfizer and Moderna.
