According to the researchers, about 20,000 people participated in clinical trials in Russia last fall. followed by a 91% vaccine efficacy. Additionally, the vaccine prevents people from getting seriously ill with COVID-19 if they become infected. The full study can be found here.
It is true that independent scientists who commented on the study, unrelated to the study, acknowledged that the Russian vaccine was criticized for its rush to develop it and the lack of transparent information.
The developers of the Sputnik V vaccine have been criticized for their inadequate haste, attempts to cut corners and lack of transparency, according to a separate comment published in the journal by Ian Jones, a virologist at the University of Reading, and Polly Roy, a professor of the London School of Hygiene and Tropical Medicine.
“However, the results published here are clear, demonstrating the scientific principle of vaccination, which means that another vaccine can join the fight to reduce the incidence of COVID-19,” the comment said.
The Russian government approved the Sputnik V vaccine with fanfare in August. The country’s President Vladimir Putin even said that one of his daughters had been vaccinated, although only a few dozen people had participated in vaccine trials at the time.

Some of the results of the first studies were published in September, but they did not meet international standards: the condition of the participants was monitored only for 42 days and there was no comparison with the results.
Meanwhile, the latest study is based on a third-stage clinical trial involving 20,000 people over the age of 18. 75 percent. they were vaccinated with two doses of Sputnik V and the rest received placebo.
2.1 thousand people participated in the research. People over 60 years. The effectiveness of the vaccine in these individuals is 92%.
Side effects are similar to those seen with the flu. No serious consequences of vaccination have been identified, and although four people died, their deaths were not related to the vaccine.

Sputnik V stimulates the body’s immune response with synthetic viral proteins and modified adenoviruses that cause common colds are used in the production of the vaccine.
The same technology is used to make the AstraZeneca vaccine, but Russian scientists are using a slightly different adenovirus for the second dose. Some experts say that this explains why Sputnik V is more effective than AstraZeneca vaccines (60-70%).

“The goal is to elicit a stronger immune response with two slightly different vaccines,” said Alexander Edwards, professor of biomedical technology at the University of Reading in the UK.
“If both doses are equal, it is possible that the immune system does not respond to the second as it should,” added the scientist, who believes that the Russian vaccine should be produced as much as possible.
In Russia, vaccination of people with Sputnik V began in December. Doctors and teachers were vaccinated first, and the campaign was then expanded to include more than a million Russians vaccinated in early January.
Outside of Russia, the vaccine is intended for use in more than ten countries: Belarus, Armenia, Turkmenistan, Argentina, Bolivia, Venezuela, Serbia, Iran, Palestine, the United Arab Emirates, and some African countries.
It is true that the countries of the European Union, including its most influential member, Germany, are already showing interest. The country’s health minister, Jens Spahn, recently said that the European Medicines Agency should approve Sputnik V if the vaccine is to be shown to be safe and effective.
Hungary also hopes to use the vaccine, with a total of more than 50 countries officially declaring a supply of $ 2.4 billion. dose of vaccine.

By the way, German Marshall analyst Daniel Heged last year 15 minutes He stated that the Russian vaccine formula was almost certainly downloaded from the servers of Western companies, which means that the vaccine is likely to be reliable and effective.
“The Russian vaccine is based on Western research and the material was obtained by the Russians with the help of cybercrime. It was hacked from the servers of several pharmaceutical companies.
Western services also confirmed that such attacks were being prepared. This means that Sputnik V is essentially a Western vaccine. The only difference is that the Russian vaccine does not go through all the lengthy screening process that is required in the West, ”Heged said.
