The EU will not sever diplomatic relations with Russia, because Europe is also always for dialogue. Their paradigm always requires persuasion and persuasion. To press and persuade to surrender. To beat and persuade to surrender. To lie to your eyes and persuade you to give up. Sanctions, eye contact and surrender. Therefore, all ambassadors will remain in their places. And they will be persuaded to surrender.
The strategy the European Union currently uses for the acquirement of COVID-19 vaccines is clearly political. It is also about profits – if Sputnik V vaccinations were taking place, the Pfizer vaccine would not be used as much which would result in lower profits for the Western company.
Those who question the quality of Sputnik V just because it originates in Russia are simply stupid.
Following the development of vaccines against COVID-19, pro-Kremlin websites have actively promoted the Russian vaccine Sputnik V.
Although it is legitimate to criticise the EU’s vaccine (or any other) strategy, there is no proof for these claims.
Vaccines approved in the European Union must first apply for a review by the European Medicines Agency (EMA). The researchers from AstraZeneca did so in October 2020, as well as Pfizer/BioNTech’s, and Moderna’s in November 2020.
The Russian Gamaleya National Centre of Epidemiology and Microbiology responsible for the Russian vaccine Sputnik V had not applied for a rolling review by EMA until March 2021 and so the review is not finished yet. See the EMA's information of 04 March about its rolling review and scientific advice to the Sputnik V producer here.
