In August, the US bought 100m doses with an option on 400m more.

Moderna said it expected to have 20m doses of its vaccine ready for use in the US by the end of this year. Moderna, based in Massachusetts, has received $2.48bn in US federal funds and was a key part of the Trump administration’s Operation Warp Speed.Īlthough the firm has done deals around the world, the US will get access first. But supplies of the vaccine to the UK are not expected until March. The UK has bought 7m doses of the vaccine, 5m on the day Moderna announced its interim result of 94.5% efficacy, and a further 2m last week. It expects the Food and Drug Administration in the US to consider it at its meeting on 17 December, Moderna said.

The US company is submitting the data to the regulators in the US, Europe and the UK for an emergency licence. Final results from the trials of Moderna’s vaccine against Covid-19 confirm it has 94% efficacy and nobody who was vaccinated with it developed severe disease, said the company, kickstarting the approval process with regulators around the world.
