This is very interesting.
We are all assuming that, once the finish line has been crossed, that is to say, in the fall, one or more of the vaccines will have gone through the three stages and will be ready to be brought to market.
First, I would like to know what difference there will be between the two vaccines that have gone through those stages. You mentioned the effectiveness, and I would like some more details. For example, could we accept one vaccine that is 60% effective and another that is 80% effective?
Then, could you also tell us about prices in the current situation, considering all this competition, the Chinese market, and our friends and enemies all around the world?
