The preliminary results of a clinical trial suggest a new treatment for Covid-19 dramatically reduces the number of patients needing intensive care, according to the UK company that developed it.
The treatment from Southampton-based biotech Synairgen uses a protein called interferon beta which the body produces when it gets a viral infection.
The protein is inhaled directly into the lungs of patients with coronavirus, using a nebuliser, in the hope that it will stimulate an immune response.
The initial findings suggest the treatment cut the odds of a Covid-19 patient in hospital developing severe disease - such as requiring ventilation - by 79%.
