British scientists are trialling a new drug that could prevent someone who has been exposed to coronavirus from going on to develop the disease Covid-19, which experts say could save many lives.
The antibody therapy would confer instant immunity against the disease and could be given as an emergency treatment to hospital inpatients and care home residents to help contain outbreaks.
People living in households where someone has caught Covid could be injected with the drug to ensure they do not become infected too. It could also be given to university students, among whom the virus has spread rapidly because they live, study and socialise together.
Dr Catherine Houlihan, a virologist at University College London Hospitals NHS trust (UCLH) who is leading a study called Storm Chaser into the drug, said: “If we can prove that this treatment works and prevent people who are exposed to the virus going on to develop Covid-19, it would be an exciting addition to the arsenal of weapons being developed to fight this dreadful virus.”
The drug has been developed by UCLH and AstraZeneca, the pharmaceutical company that has also, along with Oxford University, created a vaccine that the Medicines and Healthcare products Regulatory Agency is expected to approve for use in Britain next week.
The team hope the trial shows that the cocktail of antibodies protects against Covid-19 for between six and 12 months. Trial participants are receiving it as two doses, one after the other. If it is approved, it would be offered to someone who has been exposed to Covid in the previous eight days.
