Interesting points, I did not know about these actions in South America. I don't want to be too generous to Pfizer/Biontech and you rightly point out the need to be cautious with these companies especially if they are in such an influential position. However my guess would be that legal risks in countries with weaker rule of law protections (for reference see this report https://worldjusticeproject.org/rule-of-law-index/) is a lot higher. You might find yourself in a position where a court rules against you although you did not commit any crime – or you might presume that there is a possibility that you will be in such a position. If you want to protect yourself and have an extremely strong negotiation position, you might write very far-reaching liability clauses.

This in itself could – imo rightfully – be seen as a deplorable strategy because you are dictating these rules for a life saving vaccine. But it does not imply that you are committing any crimes at the moment.
