The whole world is stunt as the health officials in Russia has authorised the one-shot Sputnik Light version of its coronavirus vaccine for the fight against COVID-19.
This has been announced by the Russian Direct Investment Fund (RDIF) recently.
The approval is not less than a revolution as this move could help vaccine supplies go further in countries like India, with high infection rates.
As per claims while two-shot Sputnik V has 91.6 % efficacy the Sputnik Light “demonstrated 79.4% efficacy”.
“The single-dose Sputnik Light vaccine demonstrated 79.4% efficacy according to analysed data taken from 28 days after the injection was administered as part of Russia’s mass vaccination programme between 5 December 2020 and 15 April 2021,” sources quoted RDIF’s statement.
This is also claimed that the “Sputnik Light has proven effective against all new strains of coronavirus, as demonstrated by the Gamaleya Center, during laboratory tests”.
The Russian vaccine has been approved for use in over 60 countries.
But it has not yet been approved by the European Medicines Agency (EMA) or the United States’ Food and Drug Administration (FDA).
Some Western countries have been wary of Sputnik V — named after the Soviet-era satellite — over concerns the Kremlin would use it as a soft-power tool to advance its interests.
Developed by Moscow’s Gamaleya Institute, the slimmed-down vaccine, which costs under $10 a dose, has been earmarked for export and could increase the number of people with partial immunity.
One of its main potential uses is as a vaccine that can be shipped to a country in the grip of an acute outbreak which needs to be subdued quickly.
A Phase III clinical trial involving 7,000 people was under way in Russia, the United Arab Emirates, Ghana and other countries, the RDIF said. Interim results are expected later this month.
According to authorities, around 8 million Russians have so far been fully inoculated with the flagship two-dose Sputnik V, named after the Soviet-era satellite that triggered the space race in a nod to the project’s geopolitical importance for Moscow.
Russian scientists last month said Sputnik V was 97.6% effective against COVID-19 in a “real-world” assessment based on data from 3.8 million people.
The slower pace of vaccination in Russia compared to other countries with domestically produced vaccines has provoked questions over its export intentions from some European officials. The European Medicines Agency has not yet approved the shot and Austria on Tuesday said it would only buy Sputnik V after EMA approval.
“The single-dose regimen solves the challenge of immunizing large groups in a shorter time, which is especially important during the acute phase of the spread of coronavirus, achieving herd immunity faster,” said RDIF head Kirill Dmitriev.
He added that the two-dose Sputnik V vaccine would remain the main source of vaccination in Russia, which has already authorised two other vaccines for use.
Alexander Gintsburg, Director of the Gamaleya National Research Center of Epidemiology and Microbiology, said that Sputnik Light offers strong value in initial vaccination and re-vaccination, as well as boosting efficacy when taken in combination with other vaccines
“Sputnik Light will help to prevent the spread of coronavirus through the faster immunization of larger population groups, as well as supporting high immunity levels in those who have already been infected previously,” Gintsburg said.
