The frequency of the new AY.4.2 variant of COVID-19 is less than 0.1 percent of all VOI/VOC and is too low to be of concern at this time, the Indian SARS-CoV-2 Genomics Consortium (INSACOG) said. Its weekly bulletin said the vaccine effectiveness does not seem to be different for AY.4.2 when compared to other Delta variants.
