MOSCOW, Oct 2 - All the barriers to register Russia's Sputnik V COVID-19 vaccine with the World Health Organization (WHO) have been cleared and only some paperwork remains to be completed, Russian Health Minister Mikhail Murashko said on Saturday.

The Sputnik V shot, widely used in Russia and approved for use in over 70 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.
