Scientists are currently interested in the C.1.2 variant, because according to many analyzes it has genetic mutations similar to some other dangerous strains such as Delta.
1. What is the C.1.2 variant?
LA Times said that the C.1.2 variant was first discovered in South Africa, in May, and in July, South African researchers officially followed this mutation. According to the researchers, C.1.2 evolved from the C.1 variant that dominated the first infection in South Africa.
According to a report published in MedRxiv, this strain in May accounted for only 0.2% of the 1,054 genomes decoded by the expert team in South Africa. But after only 1 month, over 2,177 gene samples analyzed C.1.2 was present in 1.6%. At the peak, out of 1,326 genetic sequencing samples analyzed by experts, 7.2% were of the C.1.2 variant.
2. How dangerous is the C.1.2 mutation?
Regarding the growth rate of this strain, the researchers estimate it to be equivalent to the Delta and Beta strains when these two strains are present in South Africa. Scientists also said that C.1.2 has now spread from Africa to Asian countries, Oceania and even Europe. Specifically, this strain is now present in the Congo, Botswana, Mauritius, China, Portugal, New Zealand, Switzerland and the United Kingdom.
According to research by scientists in South Africa, the C.1.2 strain has a very worrying “collection” of mutations and warns that it is these mutations that can increase the spread of nCoV. or help them evade the Covid-19 vaccine.
Regarding C.1.2, Dr. Stuart Ray of Johns Hopkins University School of Medicine – immunologist, who specializes in infectious diseases, and virologist Ramon Lorenzo-Redondo, of Northwestern University, USA, Now, we should be careful with this mutation, but we don’t need to worry too much.
Sharing the same view, many experts around the world also said that it is too early to draw conclusions that the C.1.2 strain is resistant or not resistant to the Covid-19 vaccine. Therefore, it takes time to continue to monitor, research and analyze before making accurate conclusions.
The World Health Organization WHO is currently classifying the detected strains into two groups, including VOIs – that is, strains of interest including Eta, Iota, Kappa, Lambda, Mu, and VOCs – that is worrisome strains include Delta, Beta, Gamma, Alpha.
The basis for classifying strains into groups is based on their ability to spread, cause disease or reduce the effectiveness of vaccines. According to WHO, C.1.2 has not yet been classified by the unit.
