>So they can focus in continue saving millions of lives since December

Not sure. Are the researchers working on the vaccine are the one handling the claims? I mean, whats this thing about "focusing on saving lives" got to do with being not responsible for the product?

>It seems a fair deal for society

Only if these companies act in good faith. Knowing what we know about Pharmaceutical companies, It is beyond me why anyone would think they would..

If you said that "we were desperate so we have to take the risk of them possibly behaving bad", then it would have made much more sense.
