In India, Delta variant continues to be the main variant of concern (VoC), said the Indian SARS-CoV-2 Genomics Consortium (INSACOG).
COVID Vaccines Lower Risk of Infection With Delta Variant
Study of 621 people in the UK with mild COVID-19 infections found that people who received two vaccine doses could still pass the infection on to vaccinated and unvaccinated household members.

‘Delta (B.1.617.2 and AY.x) continues to be the main VOC in India. No new VOI (variant of interest) or VOC are noted and other VOC and VOI other than Delta are now negligible in sequencing data from India.’
"Delta, including B.1.617.2 (AY) and AY.x sublineages, continues to be the main VOC globally. As per the latest WHO update, Delta has outcompeted other variants in most countries and there is now declining prevalence of other variants among SARSCoV-2 sequences submitted to publicly available datasets or reported to WHO," said INSACOG in its bulletin. The total number of samples processed and sequenced so far is 96,312. A total of 92,800 samples have been analysed by INSACOG.
A consortium of 28 national laboratories set up in December 2020 to monitor the genomic variations in Sars-CoV-2, the Covid-19 causing virus, the INSACOG functions under the Union Health and Family Welfare Ministry.
Delta Variant Mutation may be More Transmissible
Delta AY.4.2 - the Delta variant sub-lineage has been designated a Variant Under Investigation (VUI) under the official name VUI-21OCT-01.

Meanwhile, India on Thursday reported 13,091 fresh Covid cases in the last 24 hours. In the same time span, a total of 340 deaths have also been reported, said the Ministry.

What Made Delta, Delta Variants of Coronavirus More Dangerous
The Delta and Delta Plus COVID-19 variants were less well neutralized by antibodies from infected and vaccinated individuals compared to the original virus, making them more dangerous.

Herd Immunity Difficult to Attain Against Delta Variant: Study
Herd immunity is critical in ending outbreaks. The only way of ending or preventing outbreaks of the Delta variant is by either infection with this variant or by using vaccine boosters that raise antibody levels high enough to overcome Delta’s ability to evade neutralization.
