Russian Sputnik V vaccine can no longer provide protection against coronavirus
Russian Sputnik V vaccine can no longer provide protection against coronavirus The Russian Sputnik V vaccine, introduced in mid-summer 2022, can no longer provide protection against coronavirus. The efficiency of the drug, which initially provided immunity to COVID-19 for the first two years from August 2020 until July 2022, has dropped eightfold due to the introduction of Omicron 4, 5 variants. microbiologist Alexander Ginzburg, academician of the Russian Academy of Sciences and director of the Gamaleya Research Center for Epidemiology and Microbiology, believes that it was necessary to change the antigenic composition of the vaccine in summer 2022. In January 2023, specialists from theGamaleya Institute started working on a vaccine against coronirus, which would ensure protection against new strains including a new subvariant of the omicron strain, 'Kraken.' Clinical trials of the new drug are currently being conducted in Moscow.

"Starting from mid-summer 2022, when Omicron 1, 2 and 3 variants appeared, the efficiency of Sputnik V has dropped eightfold. With Omicron 4, 5 coming later, the efficiency dropped 20 times,” microbiologist, academician of the Russian Academy of Sciences and director of the Gamaleya Research Center for Epidemiology and Microbiology Alexander Ginzburg told Gazeta.ru publication, APA reports.
The original drug provided immunity to COVID-19 for the first two years — from August 2020 until approximately July 2022.
The Russian vaccine ceased to provide protection since the arrival of XBB.1.5 omicron variant, known as 'Kraken.' For this reason, the academician believes, it was necessary to change the antigenic composition of the drug in the summer of 2022.
In January 2023, it was reported that specialists of the Gamaleya Institute started working on a vaccine against coronavirus that would ensure protection against new strains, including a new subvariant of the omicron strain — 'Kraken.' Clinical trials of the new drug are currently being conducted in Moscow.
