Russia has became the first country to clear a COVID-19 vaccine and declare it ready for use.
Russian President Vladimir Putin says one of his daughters has already been inoculated with the vaccine developed in his country.
Putin says that the vaccine underwent the necessary tests and has proven efficient, but international experts have questioned its safety.
Russian authorities have said that medical workers, teachers and other risk groups will be the first to be inoculated.
