The vaccine initiative set up by the Trump administration, previously called Operation Warp Speed, has spent around $12.4 billion (£9bn) supporting vaccine development andacquired 1.21 billion coronavirus vaccine doses, enough to immunise the population of America twice over. President Biden promised to have administered 100 million vaccinations in his first 100 days of office, and on 19 March the US passed this goal six weeks ahead of schedule. As a result, on 25 March he revised that target upwards to 200 million, and this was also achieved ahead of schedule on 21 April.
Under the Trump administration, the US purchased 300 million doses of the Oxford-AstraZeneca vaccine, 200 million doses apiece of the Moderna and Pfizer-BioNTech vaccines, and 100 million doses from Sanofi-GSK and 110 million from Novavax. The Biden government has bought 100 million more doses of each of the Moderna and Pfizer-BioNTech vaccines, and has announced its intention to purchase a further 100 million from Johnson & Johnson although that deal hasn't been finalised as yet. The Johnson & Johnson, Moderna and Pfizer-BioNTech vaccines are currently the only ones authorised for use.
President Biden had said that there will be enough doses for all Americans by the end of May. The White House is also sending four million shots of the AstraZeneca vaccine to its neighbours Canada and Mexico (1.5 million and 2.5 million doses respectively). As part of the deal, any unused vaccine must be returned to the US. It is now also donating a further 60 million doses to other countries around the world, and India is expected to be one of the key recipients.
