The World Health Organisation said its review of how Russia produces the Sputnik V coronavirus vaccine had found some issues with the filling of vials at one plant, which said it had since addressed all of the WHO's concerns, Reuters reports.
The Sputnik V shot, widely used in Russia and approved for use in over 60 countries, is undergoing a review by the WHO and the European Medicines Agency (EMA).
Their approval could open up new markets for the shot, especially in Europe.
