With First Dibs on Vaccines, Rich Countries Have ‘Cleared the Shelves’

And while Pfizer’s vaccines are already flowing to Britain, Canada and the United States, it is unclear when they will arrive in other countries. Mexico, according to an announcement, could get its first vaccines any time in the next 12 months.

Clemens Auer, a chief negotiator for the European Union, said an in an email that its contract with Pfizer for 200 million doses came with a “fixed delivery timetable,” but that he was keeping the details from the public. “Details don’t matter much,” he said, given the high volume of promising vaccines the E.U. had secured.

In Canada, the government has faced questioning over its contract with Moderna. The country secured an agreement in August for 20 million doses, with an option for an additional 36 million. The United States announced a deal for up to 500 million doses shortly after, and Britain and the European Union announced their own deals last month.
