The findings about remdesivir depart medical doctors unsure on how you can proceed, on condition that some international locations, together with the US, have already granted the drug emergency use authorization. Additionally they depart well being authorities, together with the World Well being Group (WHO), scrambling to assessment the most recent knowledge to replace their remedy pointers.
