The new results are based on data from 22,714 participants in the trial, and were published after 78 confirmed coronavirus cases were reported among the group, researchers at the Gamaleya Institute said in a statement made on Monday with the Russian Direct Investment Fund, which is marketing the shot.

Of the 78 cases, 62 occurred among participants who had received a placebo, the researchers said.
