But the study, which was published in the journal “Lancet”, which is edited by specialists, indicated at the same time, “the need for more long-term trials on the vaccine.”
According to the American “CNBC News”, the doctors who participated in the experiments conducted “two open studies for stage 1/2 in two Russian hospitals”, “in a non-random sample of 76 healthy volunteers between the ages of 18 and 60 years”.
So far, the vaccine has been shown to be “safe and well tolerated.”
The study reported no serious negative effects among the participants and confirmed that it “creates an antibody response.”
The journal’s report said: “Large, long-term trials, including comparison of the vaccine with a placebo and ongoing monitoring, are needed to determine the long-term safety and efficacy of the Corona virus vaccine.”
The study comes amid international doubts about the effectiveness of the Russian vaccine, after experts warned that “the vaccine did not complete the necessary experimental stages recognized in the scientific community.”
On August 11, Russia said it had “developed the world’s first vaccine against the virus that provides” sustainable immunity “against Covid-19 and is in the final stage of human trials.”
The vaccine was named “Sputnik” after the “first satellite that helped put the Soviet Union at the forefront of the space race during the Cold War in 1957.”
And Western researchers questioned this announcement, so “some considered that the vaccine that was developed in a hurry may be dangerous, while the last phase of experiments began only this week.”
The Russian vaccine, developed by the Gamalia Research Institute and the Russian Defense Ministry, is among the 28 vaccines that reached the third stage, but “the World Health Organization includes it only in the first stage.”
The organization said it was “in contact with Russian scientists and authorities and hopes to review the details of the experiments.”
So far, “Russia has not released data or data on vaccine development, adding to the ambiguity about it.”
