Russia today approved a third coronavirus vaccine for domestic use, although large-scale clinical trials of the shot, labeled CoviVac and produced by the Chumakov Centre, have yet to begin.
The Chumakov Centre, founded in 1955 in St Petersburg by Mikhail Chumakov, is known for its work with U.S. scientist Albert Sabin at the height of the Cold War, which led to the production of the widely used polio vaccine. Unlike the Sputnik V vaccine, the CoviVac vaccine is a "whole-virion" vaccine which means it is made of a coronavirus that has been inactivated or stripped of its ability to replicate. Deputy Prime Minister Tatiana Golikova said that CoviVac shot is given in two doses, 14 days apart. It is transported and stored at normal fridge temperatures, of 2 to 8 degrees Celsius.
