Skepticism Greets Putin's Announcement Of Russian Coronavirus Vaccine

President Vladimir Putin announced Tuesday that Russia has become the first country to approve a vaccine to prevent coronavirus infection, saying one of his daughters has already received a dose of the new prophylaxis even though that it is still under development.

The announcement of the new vaccine, dubbed Sputnik-V, has been met with initial skepticism, as it has yet to complete Phase III trials in which large numbers of people are given doses to determine whether it is safe and effective in a general population.
