Nine Latin American countries have so far agreed to buy vaccines from Pfizer: #Chile, Colombia, Costa Rica, Ecuador, Mexico, Panama, Peru, #Uruguay and the Dominican Republic. The terms of these deals are unknown since all of the deals included a confidentiality clause. In the case of Argentina, the government acceded to almost all of #Pfizer’s demands. But it insisted that Pfizer pay out in the event of negligence. Even that was a bridge too far for the drug maker.
