Through this report, here is the percentage vaccinated (at least one shot) by age group (I got the population numbers calculating from the mortality report in the case monitoring PDF):
25-34 11.9%
35-44 20.1%
45-54 29.6%
55-64 46.8%
65-74 79.3%
75-84 79.8%
85+ 66.8%
I have no idea why 85+ is lagging behind the rest of 65+ by so much. Mobility issues? Medical issues that prevent taking vaccines?
I must have figured out the population accurately because my calculation of 30.8% of the population with at least one dose matches the CDC. They seem to be administering around 1.2 million doses per week. Trying to swag the mix of J&J we can probably assume an average of 100,000 per day newly vaccinated. That's about 3.2% of the population per week. Maintaining that rate, 50% of the population of FL should have at least one shot in six weeks, roughly by 5/21.
Supply and rate of injections must increase to get everybody who wants to be vaccinated started by the end of May if we assume at least 70% want to be vaccinated.
