Ever since China commenced its vaccine diplomacy programme, with president Xi Jinping pledging to make China's easy-to-store, state-developed vaccines available across the world, hundreds of millions of doses have been shipped to more than 80 countries worldwide.Most of the doses administered in countries such as Seychelles, Chile, Bahrain, and Mongolia, which have the highest rates of inoculated populations in the world, were developed by Chinese companies Sinovac and Sinopharm.

For the below countries, their case and death trends unlikely explained by vaccination effectiveness as only 17% / 40% fully vaccinated in INDO and BRAZIL
Indonesia - 17%/31%
Brazil - 40%/70%

For China, think their their case and death trends cannot be used as proof their vaccines' effectiveness, for obvious reasons.
