Post Vaccination/VDMP/ Implementing Covid Free Zones

Ending Covid
Utilizing Population Density Maps to Identify Regions in the Process of Establishing Covid Free Zones

With the continuation of using population density maps as a key starting point in order to establish regions as Covid free zones. These areas can be determined by documenting a reduction in Covid-19 cases, as a result of implementing a combined strategy of vaccination in order to establish herd immunity. Herd immunity would be defined as the arrival of an arbitrary value, within a specified group of individuals, that reflects the numerical threshold, at which point the said population has a combined numerical value of antibodies present, by the means of either exposure through natural immunity, or via vaccination. 
Below, the population is documented utilizing a color coded key to reflect the density of the population per square mile within a given region. The dark green areas are a reflection of areas where there are the least amount of individuals present.

Obtaining a longitudinal section from the left side of the above population density map. 

Additional grid lines can be superimposed over or corresponding with a population density map in several ways such as, used to identify or define the following parameters:
County by county 
Least amount of population density per square mile 
As vaccination strategies are implemented defining areas for example:
Covid free zone
In progress testing zone (accumulated Covid-19 positive test data) 
Vaccinated zone (scheduled vaccinations in progress)
State which stage it is in regarding clearing 
Color identifiable variables can include: Green/ Dark Green/Dark Blue/Light blue/Yellow/Orange/Red/etc..  
Largest amount of cases/from the least at the end/ on a daily assessment.  
Ratios for the amount of vaccinations scheduled corresponding to number of vaccination sites.
Additional statistical correlations can include age demographics and pre-existing conditions.
