With a vaccine for the novel coronavirus still likely a year or more away, the first weapon against the virus could be one of the drugs now in clinical trials with COVID-19 patients. A new analysis out today shows that many of these drugs, which are currently manufactured or in development to treat other diseases, can be made for $1 a day per patient, or less. If any prove effective against the novel coronavirus, a coordinated international effort will be needed to ensure they are made affordable for people worldwide, the researchers argue.
