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 日期間,香港 7·4 百萬人口接種了 13·2 百萬劑疫苗。我們分析了輕度或中度 (n=5566)、重度或致命 (n=8875) 和致命 (n=6866) COVID-19 確診病例的數據。在測試呈陽性後的 28 天內,接種兩劑任一疫苗可預防嚴重疾病和死亡,在 60 歲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] ) 與 CoronaVac (69·9% [64·4–74·6]) 相比。三種劑量的任一疫苗都提供了非常高水平的保護,可防止出現嚴重或致命的後果(97·9% [97·3–98·4])。
