It is true that there is skepticism by specialists in the USA, Germany, France and other countries about this vaccine.
But Russia is betting on everyone that the vaccine is effective.
Proof of this is that dates for massive vaccination have already been planned.
Hopefully the Sputnik-V vaccine will be a success. And we all have the opportunity to access it to be able to return to normality and recover the economy.
Before releasing it to the public, I believe it has passed all the necessary requirements of WHO. And if Putin's daughter received it (no red tape), then they are pretty confident with themselves.

Right now, we can't assess its efficiency because it will take time if that vaccine will really do its job. Let us hope that they really observe all the necessary protocols before releasing it to public use.
