Findings
Between Dec 31, 2020, and March 16, 2022, 13·2 million vaccine doses were administered in Hong Kong’s 7·4-million population. We analysed data from confirmed cases with mild or moderate (n=5566), severe or fatal (n=8875), and fatal (n=6866) COVID-19. Two doses of either vaccine protected against severe disease and death within 28 days of a positive test, with higher effectiveness among adults aged 60 years or older with BNT162b2 (vaccine effectiveness 89·3% [95% CI 86·6–91·6]) compared with CoronaVac (69·9% [64·4–74·6]). Three doses of either vaccine offered very high levels of protection against severe or fatal outcomes (97·9% [97·3–98·4]).
2020 年 12 月 31 日至 2022 年 3 月 16 日期间,香港 7·4 百万人口接种了 13·2 百万剂疫苗。我们分析了轻度或中度 (n=5566)、重度或致命 (n=8875) 和致命 (n=6866) COVID-19 确诊病例的数据。在测试呈阳性后的 28 天内,接种两剂任一疫苗可预防严重疾病和死亡,在 60 岁或以上的成年人中使用 BNT162b2 的有效性更高(疫苗有效性 89·3% [95% CI 86·6–91·6] ) 与 CoronaVac (69·9% [64·4–74·6]) 相比。三种剂量的任一疫苗都提供了非常高水平的保护,可防止出现严重或致命的后果(97·9% [97·3–98·4])。
