President Joe Biden’s administration plans to send about 4 million doses of AstraZeneca Plc’s Covid-19 vaccine to neighboring Mexico and Canada, White House Press Secretary Jen Psaki said. The deal emerged alongside an announcement by Mexico that it will crack down on the flow of migrants across the U.S. border. The vaccine export plan is under assessment, Psaki said, and would involve the U.S. sending Mexico 2.5 million doses and Canada 1.5 million doses. It would represent the first known exports by the U.S. of domestically produced vaccines. Biden has been under pressure to use its stockpile to help its neighbors, which have been struggling to obtain supplies. The administration has said the U.S. plans to acquire more doses than it needs to inoculate its population in case there’s a need for booster shots, or for other contingencies. Biden has said there will be enough vaccine by the end of May for all adults in the U.S. Subscribe to our YouTube channel: https://bit.ly/2TwO8Gm Bloomberg Quicktake brings you live global news and original shows spanning business, technology, politics and culture.
