Russia is starting its COVID-19 vaccination programme, with clinics in the capital Moscow vaccinating those most at risk from the virus.
Its own vaccine Sputnik V, which was registered in August, is being used.
Developers say it is 95% effective and causes no major side effects, but it is still undergoing mass testing.
BBC News reports thousands of people have already registered to get the first of two jabs over the weekend, but it is unclear how much Russia can manufacture.
Producers are only expected to make two million doses of the vaccine by the end of the year.
