The global health agency’s COVAX Facility is a multilateral initiative running trials on several potential vaccines. The latest payment will allow Mexico to acquire enough doses of a vaccine to immunize up to a fifth of the country’s population of around 125 million people, the foreign ministry said.

The foreign ministry statement added that the government had presented the “risk guarantee” paperwork for another $20.6 million, which it described as part of the contractually required commitments to access the eventual vaccine supply. The statement did not provide additional details on the second payment.

According to the health ministry, Mexico has confirmed nearly 810,000 cases of the highly-contagious respiratory disease caused by the coronavirus, along with more than 83,000 recorded deaths, though both likely represent only a fraction of the true number of infections and fatalities due to little testing.

The government signed its COVAX contract late last month.
