The first registered vaccine to combat COVID-19 is Russian and is called Sputnik V. After its announcement, there were several reactions from countries that clearly showed that they did not trust the vaccine in the country of Vladimir Putin. The low number of tests also left some doubts!
However, the latest study findings on the Russian coronavirus vaccine reveal that it is safe, effective, and without serious side effects.
Russian COVID-19 vaccine without adverse results and with immune response
The preliminary results of the Russian vaccine are quite optimistic. On the other hand, the World Health Organization believes that a fully effective vaccine for COVID-19 will not arrive for another year. The new study was published in the well-known British scientific journal "The Lancet." The trials involved 76 people for 42 days in the first two stages of vaccine development. According to the results, "there were no adverse outcomes"From the Sputnik V between the people tested and the compound succeeded"provoke an immune response".
The vaccine was tested in two stages, applying at each stage to 38 healthy adults, aged 18 to 60, reveals the BBC. In the first phase, we tried to see if the vaccine was safe, without causing side effects in people's bodies. In the second phase, the authors said they had identified the effectiveness of the Sputnik V vaccine. According to the information, the vaccine produces a response from T cells, a type of defense cell in the body, within 28 days.
According to the BBC, the Russian vaccine uses two adenovirus vectors: one is recombinant human adenovirus type 26 (rAd26-S) and the other is recombinant human adenovirus type 5 (rAd5-S), which have been modified to express the protein S of the new coronavirus. The virus uses protein S to enter cells and infect them.
It should also be noted that the tests carried out were carried out with vaccines in frozen format, already thinking about the fact that they will be used for large-scale vaccination.
Some patients have had side effects, but none of them are considered serious: high fever (50%), headache (42%), lack of energy (28%), and joint and muscle pain (24%). The symptoms are similar to those of other types of vaccines. To evaluate the efficacy of the vaccine, the scientists compared the plasma of the inoculated volunteers with that of infected people. According to them, the antibody response was higher among the vaccine samples.
