New Covid variant C.1.2 may be more infective, evade vaccines

New research has shown that the Covid-19 variant C.1.2, which was detected in South Africa and other countries worldwide, may be more transmissible than previously thought and could evade vaccine protection.

Scientists from the National Institute for Communicable Diseases and the KwaZulu-Natal Research Innovation and Sequencing Platform in South Africa stated that the variant of interest was first discovered in the country in May 2018.

According to scientists, this Covid variant was discovered in China, Mauritius and the Democratic Republic of the Congo as of August 13.

Scientists found that South Africa has a steady increase in the number C.1.2 genomes each month.

This increased from 0.2% of genomes that were sequenced in May, to 0.2% of those sequenced in May. According to them, the available sequences for C.1.2 might not be representative of the frequency and spread of the variant in South Africa or around the globe.

The peer review of the study has yet to take place.

It stated that C.1.2 had mutated significantly compared to C.1, which was one of the lines which dominated the S-CoV-2 infection in the first South African pandemic.

The study’s authors stated that this is similar to the rises seen in Beta and Delta variants during early detection.
