A new nasal spray which could protect people from all Covid variants is set to start human trials.
The researchers used a supercomputer to design proteins which target ‘vulnerable sites’ on the surface of Covid-19.
They targeted the virus’ infectious machinery’ in three places rather than one, making the drug far less likely to detach than other treatments. ‘When we put the spike protein and our antiviral therapeutic in a test tube together for a week, they stayed connected and never fell apart.’The treatment reduced Covid symptoms and prevented infections, the researchers found after testing it on mice with a nasal spray.
Covid cannot infect the body without binding to the receptor, which suggests the treatment will work against new variants.
