Use convalescent plasma
The FDA have announced they will allow doctors to use convalescent plasma, collected from people who recovered from COVID-19, to treat those who are in critical condition from the virus.
Although there is not much evidence that this is an effective treatment, the FDA believe that because this plasma contains antibodies against the virus it could help patients suffering from the disease. The use of convalescent plasma has been studied and utilized in other pandemics like the H1N1 flu pandemic, and also to treat other coronavirus epidemics like SARS and MERS.
