OK, a little chart for today. I have been tracking vaccine allocation to Texas and the amounts vaccinated as reported by the state.
This chart shows you a solid blue line showing total first shot federal allocations for Texas, combining Pfizer and Moderna. The date on the chart is the first date of the week of the allocation, so the earliest possible data that shots could have been received. The vertical axis shows the percent of Texans that could have been covered by the allocations. The dashed blue line shows actual first shot results, shots in arms reported to the tracking database, and then shown on the dashboard.
The orange lines show the same thing for the second shot, solid orange represents allocations and dashed orange is shots in arms, reported and shown on the tracking dashboard.
The lines go flat on the top because I assume that there will be no more allocations other than what Texas has been promised so far. That's probably not true, they will probably continue upward.
There will always be a lag between shot allocations and shots reported to the dashboard. Right now the lag is pretty big, like 2.5 weeks. The state can narrow the gap by getting better at giving shots, but ultimately can't go any faster unless allocations increase.
