new AY.4.2 mutation of the coronavirus is less than 0.1% of all variants of interest or concern at the moment, said the Indian SARS-CoV-2 Genomics Consortium (INSACOG) in its weekly bulletin on Sunday.
As per the panel, the frequency currently is too low to be concerning and the vaccine effectiveness against it does not seem to be different when compared to other Delta variants. "There is currently no biological basis for increased transmissibility of AY.4.2, as judged epidemiologically, and assays are in progress," it said.
The INSACOG noted that Delta (B.1.617.2 and AY.x) continues to be the main variant of concern in India and no new variant of interest have been noted till now.
