US President Donald Trump’s administration has secured almost all the world’s upcoming supply of the drug remdesivir.
The drug, produced by the firm Gilead Sciences, is the first approved by authorities in the US to be used to treat Covid-19.
It has been shown to help people recover faster from the disease.
A statement from the Department of Health and Human services says Trump struck an “amazing” deal with Gilead for 500,000 doses which amounts to 100% of Gilead’s production in July, 90% of it in August and 90% in September.
A treatment course of remdesivir is, on average, 6.25 vials.
