RE:RE:RE:RE:RE:RE:RE:RE:Some Thoughts about This or ThatI don't understand the announcement because:
1. If they claim 90% effective but they did not say all 43K were under monitor and continuous testing for infection. 10% not effective would mean 4.3K people infected but why 94 confirmed cases.
2. To prove the vaccine's effectiveness, all participants have to expose to the virus to prove it is 90% effective. Did they do that? No details. If they were not exposed to the virus in a controlled manner how can they determine the effectiveness?
3. "Trial to be continue until 164 cases". Will they wait for next millenium? What is the significance of 164 cases?
