Russia's Federal Service for Rospotrebnadzor has released new information about a vaccine tested against coronavirus infection.
Scientists plan to complete clinical trials of the vaccine in September.
The tests began on July 27.
14 volunteers were vaccinated in the first stage and 43 in the second stage.
According to Gadin.Net, Ridus quotes officials as saying that all the volunteers are feeling well and no side effects have been reported.
The only thing that worries them is the pain of the injection site, which completely disappears the next day.
Russia registered the world's first coronavirus vaccine on August 11. It was named Sputnik V.
