Was shocked at what I was seeing: South African scientists who spotted Omicron variant
Raquel Viana, Head of Science at one of South Africa's biggest private testing labs, sequenced the genes on eight coronavirus samples - and got the shock of her life. The samples, tested in the Lancet laboratory, all bore a large number of mutations, especially on the spike protein that the virus uses to enter human cells. I was quite shocked at what I was seeing. I questioned whether something had gone wrong in the process," she told Reuters.
