Russia approves world's first coronavirus vaccine

Russian President Vladimir Putin announced Tuesday the approval of a coronavirus vaccine developed by the Moscow-based Gamaleya Institute. The vaccine is named Sputnik-V, and it has yet to go through Phase 3 trials.

Putin said, "A vaccine against coronavirus has been registered for the first time in the world this morning, I know that it works quite effectively, it forms a stable immunity."

The announcement came despite a caution last week from the World Health Organization(WHO) that Russia should not stray from the usual methods of testing a vaccine for safety and effectiveness.
