The main cause for concern about the B.1.1.7 variant of the coronavirus is that it is believed to be even more contagious than the dominant strain to date in Europe.

Above all, the mutations of the coronavirus “relate mainly to the protein of the spikes (spicules)”, indicated the report, in other words the spikes which are on its surface of the coronavirus and allow it to attach to cells to penetrate them, thus playing a key role in viral infection.

On Tuesday, December 22, American experts began first studies on the new strain of the coronavirus and according to them, there is no evidence of a higher contagiousness. “There is no tangible evidence that this virus is indeed more contagious”, but “there is clear evidence that it is more widespread in the population,” said Moncef Slaoui, senior government program adviser. vaccination program, during a press conference.

The real good news, likely to reassure the health authorities, is that it is very likely that the vaccines, already used or about to be used, are effective against the English mutation. “In terms of vaccination, there is not too much difference between these two viruses. The vaccines as they were produced should protect us”

The CEO of the BioNtech laboratory, which developed the main vaccine with Pfizer, assures that his group will be able to provide a new vaccine “in six weeks” in the event of a significant mutation of the Covid.
