Sputnik Light Vaccine Description

Russia's Sputnik Light is the first component (recombinant human adenovirus 26 serotype (rAd26) of the Sputnik V vaccine. The Sputnik Light vaccine is based on a proven and well-studied platform of human adenoviral vectors, which cause the common cold and have been around for thousands of years, as demonstrated by the Russian Gamaleya Center during laboratory tests. 

Adenoviruses, which are found in the respiratory tract and regularly cause acute respiratory infections, have become the most commonly used viruses to engineer vectors. Scientists from the Gamaleya Center have been working on adenoviral vector-based vaccines since the 1980s and now lead the world to develop these vaccines.

The effectiveness of Sputnik Light was found 79.4% based on the analysis of data from the 28th day after receiving immunization by citizens of the Russian Federation as part of the mass vaccination program in the period December 5, 2020 - April 15, 2021. The Sputnik Light vaccine elicits the development of virus-neutralizing antibodies in 91.67% of individuals on the 28th-day post-immunization. And the cellular immune response against the S Protein of SARS-CoV-2 develops in 100% of volunteers on the 10th day.

On May 6, 2021, the Ministry of Health of the Russian Federation, the National Research Center for Epidemiology and Microbiology, and the Russian Direct Investment Fund (RDIF) announced the single-component Sputnik Light vaccine registration.

The immunization of individuals with pre-existing immunity against SARS-CoV-2 with Sputnik Light can elicit the increase of antigen-specific IgG antibodies by more than 40x in 100% of subjects ten days after immunization. Sputnik Light international clinical trials included about 7,000 people from Moscow, Russia, Ghana, the United Arab Emirates, and other countries.

On May 24, 2021, the RDIF announced data from a study conducted by the Institute of Virology of the National University of Cordoba (Argentina) and the authorities of Cordoba, which confirmed 85.5% of individuals developed IgG antibodies to the SARS-CoV-2 coronavirus on the 14th day after receiving the first injection of Sputnik V.

The RDIF is Russia's sovereign wealth fund established in 2011. The Federal Government Budgetary Institution, "National Research Center for Epidemiology and Microbiology," is one of Russia’s oldest scientific research centers and celebrated its 100th anniversary in 1991.
