The World Health Organisation's chief scientist said on Friday that no vaccine for the new coronavirus should be approved for a worldwide rollout until it had undergone sufficient scrutiny and proved its safety and efficacy.
"No vaccine is going to be mass-deployed until regulators are confident, governments are confident, and the WHO is confident it has met the minimum standard of safety" WHO chief scientist Soumya Swaminathan said at a news briefing in Geneva.
