Russia’s Association of Clinical Trials Organizations, a nongovernmental agency, appeared to also have safety concerns Tuesday and asked the health minister in an open letter to delay registering the vaccine until all trials have been completed, The Wall Street Journal reported.
“It hasn’t even completed testing with participation of even 100 people,” the letter said. “It’s exactly in the course of that phase when proof of the effectiveness can be ascertained as well as information about undesirable reactions, which the vaccine can cause in various patient groups.”
