Vaccination for Infection Protection Index Formula

Relative Protection Index = Infection Rate Difference + Vaccination Rate Difference
Infection Rate Difference = Global Infection Rate - Regional Infection Rate
Vaccination Rate Difference = Global Vaccination Rate - Regional Vaccination Rate

Example 1: Vaccination for Infection Protection Index in India, using 2022-12-18 WHO data.

Global Infection Rate = 8.31%
India Infection Rate = 3.24%
Global Vaccination Rate = 162.61%
India Vaccination Rate = 132.00%

Relative Protection Index = (8.31 - 3.24) + (162.61 - 159.39) = 8.29

Example 1: Vaccination for Infection Protection Index in USA, using 2022-12-18 WHO data.

Global Infection Rate = 8.31%
USA Infection Rate = 29.77%
Global Vaccination Rate = 162.61%
USA Vaccination Rate = 195.57%

Relative Protection Index = (8.31 - 29.77) + (162.61 - 195.57) = -54.42

Example 1: Vaccination for Infection Protection Index in China, using 2022-12-18 WHO data.

Global Infection Rate = 8.31%
China Infection Rate = 0.68%
Global Vaccination Rate = 162.61%
China Vaccination Rate = 235.52%

Relative Protection Index = (8.31 - 0.68) + (162.61 - 235.52) = -65.28
