A new variant recently discovered in South Africa, was found to be the most mutated COVID-19 strain so far. Here why scientists are alarmed.
With warning signs that it may be worse than the Delta strain, the baddest variant of concern (VOC) till date, the C.1.2 has raised alarm that this may be the beginning of a potential round 2 of ‘world vs COVID-19’.
The new COVID-19 variant, has been detected not just in South Africa and at least 7 other countries which includes China, England, New Zealand, Portugal, Switzerland, the Democratic Republic of the Congo and Mauritius.
The global alarm resulted from a pre-print study released by a group of researchers in South Africa who detected the new, rapid mutations on the original C.1 strain that was detected back in January 2021.
The C.1.2, first detected in May 2021, may be more infectious and better equipped to evade many of COVID-19 vaccines currently available, as per the new study by National Institute for Communicable Diseases and the KwaZulu-Natal Research Innovation and Sequencing Platform in South Africa. The WHO is reportedly investigating and following up on the new variant.
Here’s what we know about the potential Variant of Concern C.1.2 so far.
May be worse than Delta
Although the study awaits peer review, it is being taken seriously by authorities around the world. The study didn’t just discover substantial mutation in C.1.2, but also that it is genetically farther from the original Wuhan strain than any of the Variants of Concern (VOC) or Variants of Interest (VOI) discovered around the world till date.
Moreover, the study suggests that the C.1.2 mutates twice as fast as other variants with 41.8 mutations per year.
These significant takeaways from the results of the research point out to the possibility of C.1.2 ending up as more dangerous compared to the deadly Delta variant which is globally the most potent COVID-19 Variant of Concern so far.
However, the scientists did add that further research was needed to understand and confirm where C.1.2 stands in comparison to Delta variant.
Why it could undo much of the global vaccination progress
There are two significant mutations in C.1.2 that could likely mean that the new variant can evade types of antibodies produced by some vaccines as well as those developed in people after COVID-19 infections from Alpha and Beta variants.
The new variant has mutated so fast and so far, that it is genetically distant from the original Wuhan strain, implying that vaccines that were developed based on the original strain may be rendered ineffective.
Its faster mutation rate at 1.7x to 1.8x also mirrors the pattern of emergence seen in prior dangerous VOCs. As per a scientist part of the study, the results should be considered “a hurricane warning on the next potential variant.”
Caution for India
India is bracing itself for a potential third wave of COVID-19 in the coming months. If C.1.2 renders the vaccines being currently administered ineffective, that spells a potentially disastrous situation.
While not detected in India so far, the potential easing of travel restrictions and reopening of establishments ahead of the festive season, there needs to be more caution with the C.1.2 variant being touted as vaccine-resistant.
