Earlier this month, the EU signed an settlement with Gilead to produce as much as 500,000 therapy programs of the drug for European international locations — together with the UK — with an choice to extend orders additional.

Gilead has priced remdesivir at $2,340 per five-day course. Some public well being consultants have stated the price is just too excessive for a drug that has not been confirmed to scale back the chance of demise.
