South African scientists have discovered the B.1.1.529 variant.

The latter presents an "extremely high" number of mutations according to the latter, which does not yet comment on the effectiveness of vaccines against this new form of the virus. 

A new variant of Covid-19, whose high number of mutations could threaten the effectiveness of existing vaccines, has been detected in South Africa, scientists announced Thursday.

“We have unfortunately detected a new variant which is of concern in South Africa,” virologist Tulio de Oliveira said at an online press conference.

An "extremely high" number of mutations

The B.1.1.529 variant has an "extremely high" number of mutations, according to South African scientists who had previously detected the contagious Beta variant.

At this stage, scientists are unsure of the effectiveness of anti-Covid vaccines against this new form of the virus.

The appearance of this variant is undoubtedly at the origin of the "exponential" increase in contaminations in recent weeks, according to the Minister of Health, Joe Phaahla, present at the press conference.
