A new antibody treatment is to be trialled on Covid-19 patients in UK hospitals, the BBC reports.
Monoclonal antibodies, which are potent, laboratory-made antibodies, will be given to about 2,000 people to see if they are effective against coronavirus.
It forms part of the UK Recovery Trial, which found that a cheap steroid called dexamethasone could save lives.
The first patients will be given the new drugs in the coming weeks.
Also, UK researchers are to begin trials of inhaled coronavirus vaccines.
Delivering doses directly to the lungs might give a better immune response than conventional jabs, they say.
The Imperial College London team will use two frontrunners already in development - the Oxford one recently paused in trials and one from Imperial that entered human testing in June.
