After several rounds of testing, the Covid vaccine, a joint venture between Pfizer and Bioentech, was approved for public use on December 9 as the first vaccine. Just hours after mankind began dreaming of the possibility of creating a new world by killing the coronavirus, President Vladimir Putin announced the start of commercial production of Russia's much-discussed covid vaccine, Sputnik-5. He also officially announced the mass vaccination campaign in Russia.
