According to reports, scientists have tested a new COVID-19 nasal spray treatment against mice which has reportedly proved "highly effective".
The spray has been developed by researchers from the University of British Columbia (UBC) in Canada.
The spray has proved to be effective against the Delta variant, reports claim, including against all COVID-19 variants. Reports say it could be the first step in developing the spray for humans which could take place after approval is granted.
The new COVID-19 subvariant isn’t yet causing concern among public health officials, but experts warn that the U.S. is not prepared for future variants or surges.
