life-saving Covid treatment

Exactly a year on from the discovery that a cheap steroid drug prevented Covid deaths, researchers say they have found another life-saving therapy.

It is expensive - a potent intravenous infusion of antibodies to neutralise the virus, rather than dampen the body's inflammatory response to it.

Results from the Recovery trial suggest it could help one in three of those in hospital with severe Covid.

For every 100 patients treated, experts calculate, it would save six lives.
