Looking at Fig 7 one can see the top 20 states by daily confirmed cases on 7/21/2021. The shift to weekly instead of daily reporting in Florida (FL) (also Nebraska (NE), Iowa (IA) and South Dakota (SD) have done this) results in delayed reporting of surges , (e.g. Florida updated its cases ( an increase in daily cases per Mpop from 320/day to 515/day on 7/23/2021 i.e. a 60% surge in reported cases) and a step function like curve. Figure 8 shows a scatter plot of COVID-19 confirmed cases vs the fraction of the population fully vaccinated on 7/22/2021, the bubbles are colored by the presidential candidate who won the state and the size of the bubble is proportional to the population, the two letter acronym for many states is included, the formula is the formula for the Pearson trendline (shown in blue dots) and the correlation R2.

Fig 9 plots the US daily confirmed cases and deaths against the % population vaccinated. Fig 10 plots the daily confirmed cases and deaths versus the date. It is seen that as the % of the vaccinated population increases the daily cases and deaths decrease, however as one gets to July the confirmed cases start to increase. Looking at Fig this is when the Delta variant % start to exceed 60%.
