Russian health authorities are preparing to start a mass vaccination campaign against coronavirus in October, the health minister has said.

Russian media quoted Mikhail Murashko as saying that doctors and teachers would be the first to receive the vaccine.

However, some experts are concerned at Russia's fast-track approach.

On Friday, the leading infectious disease expert in the US, Dr Anthony Fauci, said he hoped that Russia - and China - were "actually testing the vaccine" before administering them to anyone.
