> So those who claim that Russian vaccine is only on the 1/2 phase spread an outright lie.

Russian vaccine was announced back in August, when it was only on phase 1/2. In contrast phase 3 Pfizer/biontech had been well under way at that time.

Russia announced a not fully tested vaccine, proudly called it "Sputnik V". The exact words Putin used when announced it was: "As far as I know, a vaccine against a new coronavirus infection has been registered this morning, for the first time in the world". So geopolitical concerns and pride are correct assessment. No wonder it drew skepticism.
