Can vaccine booster lower the COVID-19 virus death rate?

---

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 deaths.

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

Booster for Death Protection Index Formula

Relative Protection Index = Death Rate Difference + Vaccination Rate Difference
Death Rate Difference = Global Death Rate - Regional Death Rate
Vaccination Rate Difference = Global Booster Rate - Regional Booster Rate

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

Global Death Rate = 1.03%
India Death Rate = 1.19%
Global Booster Rate = 29.46%
India Booster Rate = 16.16%

Relative Protection Index = (1.03 - 1.19) + (29.46 - 16.16) = 13.13

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

Global Death Rate = 1.03%
USA Death Rate = 1.09%
Global Booster Rate = 29.46%
USA Booster Rate = 34.15%

Relative Protection Index = (1.03 - 1.09) + (29.46 -34.15) = -4.76

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