Sputnik V: Proven Vaccine, Political Ploy, or Both?

is the Russian vaccine safe?
Vaccine Rollout so fast, in the west, is quite concerning. Russia putting out a vaccine faster than the west with less scientific scrutiny (like a phase III trial) is itself reckless. The only criticism against me is what are the standards' differences between Russia and Western scientific process of approving a vaccine for mass vaccination/public usage deployment?
