Russian study says Sputnik V vaccine has been shown to be 97.6% effective

the Gamaleya National Research Center for Epidemiology and Microbiology of the Ministry of Health of the Russian Federation and Russian direct investment fund (RDIF) has just announced that The Sputnik V vaccine has been shown to be 97.6% effective, based on the analysis of data on the rate of coronavirus infection among people vaccinated in Russia with the two dose components of the inoculant.

This is due to the fact that the Russian Ministry of Health maintains a register of vaccinated persons, as well as citizens who have been infected with COVID as part of the state’s Unified Health Information System.

This is how the data 3.8 million Russians vaccinated with the two components of Sputnik V from December 5, 2020 to March 31, 2021, the infection rate from day 35 from the date of the first injection was only 0.027%.

At the same time, the incidence in the unvaccinated adult population was 1.1% for a comparable period from the 35th day after the launch of large-scale vaccination in Russia.

As detailed, they used the following formula to calculate vaccine efficacy: infection rate among unvaccinated adult population – infection rate among fully vaccinated population – infection rate among unvaccinated adult population = 1 , 1% -0.027% 1.1%, which gave the final figure of 97.6%. Russian health authorities have also announced that vaccine efficacy data and estimates to be published in a peer-reviewed medical journal in May.

Sputnik V is approved for use in 60 countries with a total population of 3 billion people. It ranks second in the world for coronavirus vaccines in terms of the number of approvals issued by government regulators.

Among the countries where it has been approved are Russia, Belarus, Argentina, Bolivia, Serbia, Algeria, Palestine, Venezuela, Paraguay, Turkmenistan, Hungary, United Arab Emirates, Iran, Republic of Guinea, Tunisia, Armenia, Mexico, Nicaragua, Republika. Srpska (entity of Bosnia and Herzegovina), Lebanon, Myanmar, Pakistan, Mongolia, Bahrain, Montenegro, Saint Vincent and the Grenadines, Kazakhstan, Uzbekistan, Gabon, San Marino, Ghana, Syria, Kyrgyzstan, Guyana, Egypt, Honduras, Guatemala, Moldova, Slovakia, Angola, Republic of Congo, Djibouti, Sri Lanka, Laos, Iraq, North Macedonia, Kenya, Morocco, Jordan, Namibia, Azerbaijan, Philippines, Cameroon, Seychelles, Mauritius, Vietnam, Antigua-et -Barbuda, Mali, Panama and India.

As detailed, Alexander Gintsburg, director of the Gamaleya Epidemiology and Microbiology Research Institute, “the actual efficacy of the Sputnik V vaccine may be even higher than our analysis results show, since the data in the case recording system allows a time lapse between sample collection (the actual date of illness) and diagnosis. . Sputnik V has once again confirmed its high effectiveness in preventing coronavirus infections. “

On the other hand, for Kirill Dmitriev, executive director of the Russian Direct Investment Fund, “the data published by the leading medical journal The Lancet demonstrated the effectiveness of Sputnik V at 91.6%. Analysis of data on the infection rate of nearly 4 million people vaccinated in Russia shows that the effectiveness of the vaccine is even higher, reaching 97.6%.. These data confirm that Sputnik V has one of the best rates of protection against the coronavirus of any vaccine. The 60 countries which have approved the use of Sputnik V have made the right decision by choosing one of the most effective tools for the prevention of the coronavirus ”.

Main features of Sputnik V:

-The Sputnik V vaccine is based on a proven and well-studied platform of human adenoviral vectors, which cause colds and have been around for thousands of years.

-Uses two different vectors for the two injections in a vaccination cycle, providing longer lasting immunity than vaccines that use the same delivery mechanism for both injections

-The safety, efficacy and absence of long-term negative effects of adenoviral vaccines have been proven by more than 250 clinical studies over two decades

-There is no record of strong allergies caused by Sputnik V

-The Sputnik V’s storage temperature is over 2-8 ° C, which means it can be stored in a conventional refrigerator without the need to invest in additional cold chain infrastructure.

-The price of Sputnik V is less than $ 10 per dose, making it affordable worldwide.
