@siusiu 智利三分之一人口、四百万人次在二月份就接种了中国科兴疫苗，现在迎来第二波更严重的新冠大爆发……
@kumano_1 @siusiu @rahuyana@unstable.icu 三個月後WSJ對印尼大量接種科興疫苗觀察:
"Indonesia is relying heavily on the Sinovac vaccine. The shot is approved by the World Health Organization for emergency use, but wide-ranging efficacy levels from different clinical trials and a lack of transparency about the data have led to concerns among some public-health experts about the degree of protection it provides as well as how long the protection lasts.
Its efficacy in preventing symptomatic infections was as low as around 50% in a study from Brazil, though the vaccine has shown higher efficacy in preventing severe Covid-19 cases. Authorities in Chile said in April the shot was 80% effective against death from Covid-19 two weeks after a second dose."
