FDA chief apologises for overstating benefits of plasma on Covid-19

The top doctor at the US Food and Drug Administration (FDA) has apologised for overstating the benefits of plasma for treating Covid-19 patients. FDA Commissioner Stephen Hahn came under fire after his agency on Sunday gave emergency authorisation to use convalescent plasma on Covid patients. Echoing President Donald Trump, Mr Hahn touted the treatment as life-saving. Scientists quickly questioned the data provided by Mr Hahn, who suggested plasma could reduce deaths by 35%. This claim exaggerated preliminary findings from a clinic at the Mayo Clinic. 'I personally could have done a better job and should have done a better job at that press conference explaining what the data show regarding convalescent plasma,' Mr Hahn told CBS News on Tuesday.
