MOSCOW (Reuters) - Russian scientists hailed the results of their first clinical trial of a potential coronavirus vaccine on Wednesday, saying it had been proved safe and that volunteers had developed an immune response.

Speaking to a crowded room without wearing masks, three of 18 volunteers monitored over a month at the Sechenov University said they all had experienced few side-effects.
