我们的理解不同：The case split between vaccinated individuals and those

The case split between vaccinated individuals and those who received the placebo indicates a vaccine efficacy rate above 90%, at 7 days after the second dose. This means that protection is achieved 28 days after the initiation of the vaccination, which consists of a 2-dose schedule. As the study continues, the final vaccine efficacy percentage may vary. The DMC has not reported any serious safety concerns and recommends that the study continue to collect additional safety and efficacy data as planned. The data will be discussed with regulatory authorities worldwide.

• 病例可能来自注射了参照物的组，也可能来自注射了疫苗的组。然后通过一些计算，得到疫苗效率。 -uptrend- ♂ (0 bytes) () 11/09/2020 postreply 20:24:18
