Moscow, March 17: Russian scientists have begun to test vaccine prototypes for the new coronavirus, and plan to present the most effective one by June, a laboratory chief at a state biotech institute said. Russia has reported 93 cases of infection but no deaths, according to official numbers published Tuesday.

"The prototypes have been created. We are starting laboratory testing on animals, to ensure effectiveness and safety," Ilnaz Imatdinov of the Vector Institute in Siberia told the Vesti Novosibirsk television channel on Monday. "In June we will present one or two showing the best results." Coronavirus Vaccine: US Begins First Human Trial of COVID-19 Vaccination in Seattle.
