A

Different countries or regions use different sets of vaccine boosters. We can calculate a relative protection index to indicate how efficient a country of region is with its vaccine boosters to prevent COVID-19 virus infections.

This protection index is listed below by country or region. Calculation formula and examples are provided after the list.

Booster 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 Booster Rate - Regional Booster Rate
```

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

```Global Infection Rate = 8.31%
India Infection Rate = 3.24%
Global Booster Rate = 29.46%
India Booster Rate = 16.16%

Relative Protection Index = (8.31 - 3.24) + (29.46 - 16.16) = 18.37
```

Example 2: Booster for Infection Protection Index in USA, using 2022-12-18 WHO data.

```Global Infection Rate = 8.31%
USA Infection Rate = 29.77%
Global Booster Rate = 29.46%
USA Booster Rate = 34.15%

Relative Protection Index = (8.31 - 29.77) + (29.46 - 34.15) = -26.15
```

Example 3: Booster for Infection Protection Index in China, using 2022-12-18 WHO data.

```Global Infection Rate = 8.31%
China Infection Rate = 0.68%
Global Booster Rate = 29.46%
China Booster Rate = 54.70%

Relative Protection Index = (8.31 - 0.68) + (29.46 - 54.70) = -17.61
```
