Scientists in the UK have discovered a cheap and available treatment for COVID-19 patients.
They've described the use of a common steroid drug as a "major breakthrough".
The drug, dexamethasone, reduced death rates by a third for patients on ventilators, and by a fifth for patients needing oxygen.
The results have been published from the Recovery trial which is assessing a number of different possible COVD-19 treatments.
It is thought the drug could have saved between 4,000 to 5,000 lives if it had been used earlier in the pandemic.
