Mexico will shortly begin exporting AstraZeneca coronavirus vaccines to other Latin American nations, the government has said, under a joint production agreement with Argentina hit by a series of delays.

A first shipment of 800,000 doses will be sent to Argentina this weekend, while Mexico will also receive its first batch, the government said, after delays blamed on a shortage of packaging supplies.

Mexican Foreign Minister Marcelo Ebrard told reporters that it had been a “long and complicated” process, according to AFP.
