“Dangerous on paper”, “Less effective vaccines against him but it makes sense”: What do we know about the new variant with an “abnormal” mutation rate?

South African scientists are monitoring a new variant of the corona virus with an abnormal mutation rate and its frequency has been steadily increasing in recent months. This variant, known as C.1.2, is said to transform almost twice as fast as other types already found. So it can be very contagious and can easily escape from the immunity obtained by vaccination or from previous contamination with Govt.

If found in all provinces of South Africa and in countries such as China, Mauritius, New Zealand, DRC, Switzerland, Portugal or the United Kingdom, scientists say this variation is still insufficient. “Variation of interest” or “confusing variation”.

“Dangerous on paper, but not practical”

Tom Ventiers, Professor of Biostatistics at KULeuven, was questioned by our colleagues about this new variant Newspaper And Antwerp Gazette. If he admits the danger of this new variant, the scientist is still not worried: “On paper, it looks like a dangerous variant, but in practice it’s not. I read all these variations carefully, and by my calculations the virus must have had a greater impact than it already has. We see.

Because the law of the strong in virology also rules. “Variation with higher evolutionary power prevails compared to existing variants”, Explains Tom Ventiers. “However, by my computational method, only two types stand out: the alpha variant [variant britannique] Especially the delta variant [variant indien], The currently dominant variant. ” However, the professor says“There is a slight drawback with this calculation method because the variation is already progressing. But so far there is no other reliable method.”

And in the future?

But what can be expected from this new C.1.2 variant? “Genetic vaccines of this variant appear to be less effective against it. That makes sense.”, Explains Tom Ventiers. “Developed antibodies do not recognize the new virus. In the case of C.1.2, the evolutionary advantage is not yet known. [c’est-à-dire d’importantes mutations qui pourraient lui permettre de se propager plus efficacement par exemple]But, when a virus takes a big leap, it creates new changes, so we often see new ways to dominate. ” Mutations are very dangerous.

In short, if we do not yet have to dramatize the meaning of the C.1.2 variant, it is even more important to observe it over the next few months …
