There is currently a Government presentation occuring around the SInovac vaccine. The study is apparently based on 2m people who have had both jabs.
On Day 14 after the second jab it is purportedly.....
65% - 69% effective at preventing symptomatic Covid-19
83% - 87% effective at preventing hospitalisation
84% - 92% effective at preventing the need for ICU
73% - 86% effective at preventing death.
I'm not really sure about how those statistics work together. Intuitively I would have expected the statistical effectiveness of the vaccine to have increased with the severity and quantity of each level.
Perhaps the answer is in the overlap.
Anyway, it's all better than 50.6% so I guess it's good news for us.
