We used to follow the race among companies and nations to get the first covid-19 vaccine. We've lost interest in that one as the world has gotten several vaccines of varying efficacy.
Then in the US we had the race among states to vaccinate their citizens.
Remember when West Virginia jumped out to an early lead. It seemed so unlikely, but turned out they had relied on their pharmacies and a reasonably centralized model. But WV has faded.
Four days ago Politico noted that New Mexico was leading. Again they were using a centralized registry system. Both WV and NM were working against some unfavorable demographics: older people in both, Hispanics in NM, etc.
For a while the Dakotas were right up there near the top, but I don't remember a news piece on that.
Today the Northeast seems on the verge of taking the lead, at least according to this. You can click on the column headings to sort. Maine, New Hampshire, and Connecticut lead NM, with Vermont, Massachusetts, and Rhode Island filling out the top 7 states.
I know my cousin, a MA resident, has had problems with the way they've handled registration and vaccination. Extrapolating that to the rest of New England with any additional facts to support my theories, I'm guessing that New England's general advantages have enabled their recent gains, overcoming some early problems in organization.
I'll be waiting to see how the states have done after the dust settles, and how their accomplishments compare to their work on other vaccines.
