It would be easier believing you if you didn't spend all your time on this site defending China...

  Just have a look at the (non China) data from a real world Sinovac vaccination campaign yourself: https://www.minsal.cl/wp-content/uploads/2021/04/Effectiveness-of-the-inactivated-CoronaVac-vaccine-against-SARS-CoV-2-in-Chile.pdf https://www.minsal.cl/wp-content/uploads/2021/04/Effectivene... I see 67% effectiveness of preventing symptomatic cases for Sinovac. I'm not sure where the 80% comes from, they could be talking about AstraZeneca.

    The Seychelles has been using a Sinopharm vaccine, not the Sinovac one. They're similar vaccines, but there could be slight differences. The WHO just approved a Sinopharm vaccine (called "BIBP"), and has stated,[1] > A large multi-country Phase 3 trial has shown that 2 doses, administered at an interval of 21 days, have an efficacy of 79% against symptomatic SARS-CoV-2 infection 14 or more days after the second dose. There are two different Sinopharm vaccines, but I think that BIBP is the one being used in the Seychelles. And yes, as you note, the Phase III studies were conducted outside of China. In order to conduct a Phase III study, there has to be community transmission of the virus, meaning that Phase III trials are impossible in China right now. You would get the same result for the vaccine and placebo arms of the trial: no infections. 1. https://www.who.int/news-room/feature-stories/detail/the-sinopharm-covid-19-vaccine-what-you-need-to-know https://www.who.int/news-room/feature-stories/detail/the-sin...
