Del Bigtree has really packed a lot into this 2 hour show. Watch Episode 190 of the Highwire titled “The Great COVID Reset” and is found on https://thehighwire.com/watch/
Among the discussion he points out the flawed logic in both the Pzifer and now the Moderna vaccine trials announcements of 95% efficacy. Pzifer announced first this sort of number in their phase 3 trial with 48,000 participants of which something like 94 got the COVID19 disease. Amongst those 9 were in the vaccine group and 86 in the control or placebo group.
In the case of Moderna, they had 30,000 in the phase 3 trial. They are split 15,000 in the vaccine group and 15,000 in the placebo group. In this case the placebo is actually something like a saline solution according to Del. In most other trials, like AstraZeneca, those in the control group got a Meningitis vaccine.
