At the microphone of Europe 1, researcher Alain Fischer returned to the announcement of Vladimir Putin, who said on Tuesday that Russia had developed the "first" vaccine against the coronavirus. "We have no information of a scientific nature," he laments. 

Barely unveiled, the announcement provoked reactions that were sometimes cautious, such as that of the World Health Organization, but also others, very critical. On Tuesday, Russian President Vladimir Putin assured that Russia had developed the "first" vaccine against the coronavirus, specifying that it gave "lasting immunity". At the microphone of Europe 1, Alain Fischer, immunologist at Necker hospital, denounces an "non-credible" announcement.

For the researcher, the Russian announcement is "completely surprising and not scientifically founded, therefore not credible". Listing the shortcomings of this vaccine, Alain Fischer notes in particular "that there is no scientific publication reporting the development of this vaccine. So we have no information of a scientific nature."

"A political announcement effect"

"We know that they probably started some clinical trials in humans not long ago," Alain Fischer said of Russian researchers working on this famous vaccine. But, he adds, "they have not taken the essential step which is to do a clinical trial on a large number of volunteers."

Alain Fischer therefore considers that Vladimir Poutine's declaration is "an effect of political announcement". And the doctor concluded: "The fact of giving some kind of official authorization to a vaccine at this stage is nonsense. It is scientifically totally non-rigorous".

Regarding the Russian announcement, the World Health Organization said that before any "prequalification" on its part, it had to examine by "rigorous procedures" all the data "collected during clinical trials" . For its part, Berlin expressed doubts Tuesday on "the quality, effectiveness and safety" of the vaccine.
