According to European experts, the effectiveness of the product is 77.8%. At the same time, more than 24.4 thousand Indian residents aged 18 to 97 took part in the test. They were randomly divided into two groups: one injected with two doses of the drug, and the other with a placebo.
Of the important points of the experiment, it can be noted that scientists recorded 16 cases of severe COVID-19, with only one in the experimental group, while the placebo group accounted for 15 cases.
Recall that at the beginning of 2021, The Lancet also published the results of the third phase of the Sputnik V trials. Then the pages of the magazine said about 91.6% of the effectiveness of the domestic vaccine.
