Disproof
This is a recurring disinformation narrative from pro-Kremlin outlets, trying to portray Russia's Sputnik V vaccine as the best in the world and accusing the West of having a prejudiced attitude towards it.
Russia's claim about the allegedly high efficacy of Sputnik V is based on an article from The Lancet which was published in February 2021. It asserted that Sputnik V’s efficacy was 91.6 per cent without considerable side effects. The article seemed to be a study carried out mostly by Russian experts. There are some doubts as to Sputnik V’s efficacy, especially where the trial procedures are concerned (see here and here).
The World Vaccine Congress Washington 2021 recognised Moderna as the world’s best anti-COVID vaccine, which made Sputnik V’s developers raise questions and call the decision ‘a strange choice’. Contrary to what is claimed, this choice was not biased. Sputnik V does have some serious disadvantages, which has made several countries reject it. Brazil rejected Sputnik V for safety concerns in April 2021 and Slovakia sold most Russian Sputnik V coronavirus vaccines back to the country of origin in July 2021. Argentina's President Alberto Fernandez tested positive for COVID in April 2021 two months after being jabbed with Sputnik V, which was negative publicity for the Russian vaccine.
There is neither Russophobia nor any political bias whatsoever in the way the European Medicines Agency (EMA) is dealing with the Sputnik V vaccine. EMA and EU leaders have publicly stated they will welcome Sputnik V if it meets the applied standards for vaccines. A rolling review by EMA is in progress and EMA Executive Director Emer Cooke said in March 2021 she hoped that the Sputnik V vaccine would be approved.
