Covid vaccine distribution by state: Tracking the doses

Distribution to more than 600 locations in all 50 states was set to begin within 24 hours of federal clearance of the Pfizer-BioNTech vaccine. These locations are primarily large health-care systems able to handle the vaccines and their storage at ultracold temperatures. If the Moderna vaccine is approved in December, supply to the states will increase greatly.

According to the official CDC guidance to the states, the first to receive the vaccine are health-care personnel — because of their exposure to the virus and their critical role of keeping the hospitals functioning — and residents and staff of nursing homes, as they account for nearly 40 percent of deaths from covid-19.

The next priorities may be essential workers (think of food, utilities, transportation, police and maybe teachers), then everyone with a preexisting condition like diabetes, heart problems or obesity, and older adults. These are provisional priority groups, based largely on federal recommendations. States will have the final say on who gets the shots and where they are administered. In Illinois, for instance, Gov. J.B. Pritzker (D) said he would send the first vaccines to health-care workers in the counties with the highest death rates.

The CDC advisory committee spent several months modeling allocation scenarios that would spread the disease while also offsetting health inequities. Black, Hispanic, Asian and Native American people are dying from covid-19 at a higher rate than White people because they often work in jobs that require daily interaction with the public, and they have unequal access to health services and insurance.

Methodology

The share of vaccines to be distributed to each state was estimated based on the proportion of adults in that state, unless states have reported the numbers.

The national and state counts of the prioritized groups such as medical workers and residents of adult congregate care facilities are from estimates by Ariadne Labs of Boston and Surgo Ventures in a project funded by the Patrick J. McGovern Foundation. The estimates prevent double-counting from overlaps between groups. For instance, medical workers can also have preexisting conditions. The groups were modeled on vaccine distribution guidance from the National Academies of Science, Engineering and Medicine. You can read the list of sources and the full methodology used by Ariadne Labs for counting the number of people in each group and adjusting for overlap here.

The Post worked with Ariadne Labs to adjust the prioritized groups to be closer in order to directions that have been given so far by the CDC Advisory Committee on Immunization Practices. ACIP has only formally identified a priority for the first set of vaccines being distributed in December, but proposed priority groupings were used for subsequent vaccine distributions for 142 million high-risk people. The priority recommendations from the CDC are not binding on states or large cities to which the vaccines are being sent. The Post will update this graphic with details from states on how vaccines are being distributed and prioritized in states.

Vaccines are also being distributed to the Defense Department, State Department, Department of Veterans Affairs, Federal Bureau of Prisons and Indian Health Service. Descriptions for how those will be allocated by state or particular populations are not included at this time.
