The developers of the single-dose Russian anti-COVID Sputnik Light vaccine claimed that the preparation is 70% effective against the delta variant of the coronavirus three months after inoculation.
The Gamaleya Center, which developed the vaccine – it is the first dose of the Sputnik V vaccine – and the Direct Investment Fund of Russia (FIDR) that markets Russian preparations abroad – explained that this data was published on the medRxiv website.
The analysis also shows, always according to the Russian authorities, an efficiency greater than 75% among the population under 60 years of age.
The FIDR and the Gamaleya Center assure that the efficacy of Sputnik Light “is superior in comparison with some two-dose vaccines, which have shown a significant decrease in their efficacy – down to below 50% – against the delta variant five months later. injection ”.
The Russian analysis is based on comparative data of 28,000 people who received the single-dose versus a control group of 5.6 million citizens who were not vaccinated.
The developers also affirm that the efficacy of the vaccine as a booster dose of other vaccines against the delta variant is close to that of the two-dose Sputnik V preparation, that is, 83% to avoid coronavirus infection and more than 94% to prevent hospitalization.
Studies are currently underway on combining Sputnik Light with preparations from other producers in Russia, Argentina, Azerbaijan and the United Arab Emirates.
The single-dose preparation has been authorized so far in about 15 countries and will be produced in more than ten countries (China, India, South Korea, Vietnam, Mexico, Argentina, Serbia and Turkey, among others).
