Russian President Vladimir Putin on Tuesday announced the launch of the world's first Coronavirus vaccine, reported AFP news agency.
The president also asked Health Minister Mikhail Murashko to keep him informed about the vaccine, while at the same time noting that he knows "it works quite effectively" and "forms a stable immunity".
Putin emphasized that the vaccine underwent the necessary tests. He added that one of his two daughters has received a shot of the vaccine and is feeling well, according to Associated Press.
The vaccine's registration is conditional and trials will continue while production gets underway, said Murashko.
Russian health ministry had earlier said mass vaccinations could begin by October. Murashko had said members of "risk groups," such as medical workers, may be offered the vaccine this month.
In an earlier report, the final check-up of volunteers testing the coronavirus vaccine, which is developed by Gamaleya National Research Center of Epidemiology and Microbiology, showed immunity in all participants, the Russian Defence Ministry said.
Clinical trials of the vaccine began on June 18 and included 38 volunteers. All of the participants developed immunity. The first group was discharged on July 15 and the second group on July 20.
