MOSCOW — Russia has named its first approved COVID-19 vaccine Sputnik V for foreign markets, a reference to the world's first satellite and what Moscow sees as its success at becoming the first country to approve a vaccine, a top official said on Tuesday.

Kirill Dmitriev, head of the country's RDIF sovereign wealth fund, said Russia had already received requests from more than 20 countries for 1 billion doses of its newly-registered COVID-19 vaccine.
