The world is still fighting the coronavirus that has knocked out its second new variant. Researchers in South Africa say a new strain of the coronavirus Sars-CoV-2 has been discovered in the country. He warns that this variant can spread quickly and that the coronavirus vaccine may be less effective. This type of coronavirus is named C12 (Covid C12 variant in South Africa).
Scientists at the National Institute for Communicable Diseases (NICD) and their counterparts at the KwaZulu-Natal Innovation and Sequencing Platform (KRISP) have described C12 as a “potential type of interest.” He said the variant was found in South Africa in May this year. Researchers claim that this type has since appeared in the Democratic Republic of the Congo, Mauritius, China, England, New Zealand, Portugal and Switzerland. He added that C12 has more variations than other “Variants of Concern” and “Variants of Interests” variants.
Genome sequence of variants is increasing every month
The study, conducted by researchers, is pending review and was posted in the pre-print repository MedRxiv on August 24. That said, the number and frequency of C12 sequences present in the world, including South Africa, are not properly represented. It has also been found that the genome number of these new variants is increasing every month in South Africa. Genome ranking was 0.2 percent in May, rising to 1.2 percent in June and then 2 percent in July. The authors of the study likened the increase to an increase in beta and delta variants in South Africa.
How does the C12 variant make the vaccine less effective?
Researchers have described how C12 penetrates the protection provided by the Covid-19 vaccine. He wrote, Mutations N440K and Y449H have been found in the sequence of C12, which are known to eliminate immunity from certain antibodies. These mutations help avoid antibodies to other parts of the virus as well. This phenomenon of weakening of antibodies can also be seen in people whose body has made antibodies to fight beta and delta variants. According to John Hopkins University, 3,08,747 cases have been reported in South Africa in the last 28 days.
