Russia requests the registration of this product in the EU. More than 15 countries are already using Sputnik V to fight the pandemic.
The researchers discussed the “intermediate results” of a major phase III trial involving 20,000 volunteers. These results are consistent with previous data. 91.6 percent. efficacy means that 91.6% of the vaccinated group was registered. fewer cases per 100 people than in the control group. Consequently, the efficacy of Sputnik V is similar to that of the Moderna and Biontech / Pfizer vaccines and superior to that of AstraZeneca.
Serut side effects have been rarely reported with Sputnik V, but researchers have not linked them to the vaccine. Most of the volunteers experienced “mild” side effects, such as flu-like symptoms or pain in the hand. Four deaths were also reported during the study, but they were not related to vaccination. One volunteer suffered a stroke.
According to Russian researchers, the Sputnik V vaccine has also been tested in more than 2,000 people over the age of 60. In this group, the vaccine was “equally effective and well tolerated.” However, this study is not yet complete. In total, the vaccine must be tested on 40,000 volunteers. The vaccine was registered in Russia more than half a year ago.
There was then international criticism for allowing the product to be widely used, even though major trials had not yet started. The first details of the vaccine were published by researchers in The Lancet in early September.
Researcher Polly Roy from the London School of Hygiene and Tropical Medicine said there has been criticism of the vaccine due to its rapid development and lack of transparency. However, the results now available are unequivocal.
Denis Logunov, from the Gamalea Center for Research in Epidemiology and Microbiology, which developed the vaccine, said: “Several vaccines based on different mechanisms of action are needed to stop the COVID-19 pandemic. Sputnik V contributes to the diversification of vaccines.
