The head of the Gamaleya Center, Alexander Gintsburg, said that he wants to identify those who received a placebo and vaccinate
According to him, the Ministry of Health approved the termination of the recruitment of volunteers, "due to the fact that everything is proven there, and the pandemic is coming and a placebo is not good at all."
After mass vaccination started, many of those who received a placebo found out after testing and decided to get vaccinated to be protected from coronavirus.
According to a Meduza source close tovaccine developers, with the start of mass vaccination, volunteers began to withdraw from the trials: this jeopardized the study because the placebo group was smaller, and it is not known how to compare the results of people who received the vaccine and those who received a placebo.
In essence, the study has failed; its purpose is notachieved. There was a change in the rules of the game during the game. The study will not have correct efficacy results because the placebo group was lost.
