Another example: the cheapest vaccines against Covid19 were the Chinese Coronavac and the Russian Sputnik. Almost all the western vaccines were purchased by the western countries in the first semester of 2021. If only western vaccines were available, the developing countries could have started the mass imunization program only in the second semester of 2021. None should think that the developing countries should let more people die only to avoid the Chinese and the Russian vaccines and to support democracy.
A curious example as both vaccines were comparatively rubbish, though for different reasons (i.e. on paper Sputnik wasn't so bad, but there were severe quality control issues in the production process).
That Sinovac saved lifes in Chile is not really something that is up for debate. The problem is that they weren't effective against the new variants, but in the first semester of 2021 which is the period we are talking about they caused a very sharp reduction in the amount of contagions and deaths in those over 60 (the age group where it was applied)
