70% efficacy at 2c-8c storage for $4 is indeed excellent but many comments here go to "but modena is 95% efficacy whyyyy" and "they're underselling it"
1/5th the price, and no need for freezers. This vaccine is huge. I pray for more like this.
That makes no sense since there are no tested regimes with 70% effectiveness. The reporting should say there is a vaccine regime with 90% effectiveness, and add a footnote that another regime that will not be used had a far lower rate of effectiveness.
Thee's another regime that we can all just forget about because it uses the same vaccine but with a different method of delivery that will be discarded in favor of the method proven far more effective. Averaging the two makes no sense.
