Delta sub-lineages unlikely to be more transmissible than parent variant: Government panel

NEW DELHI: Delta variant sub-lineages — AY.1 and AY.2 — are unlikely to be more transmissible than Delta said INSACOG, a consortium of government panel involved in genome sequencing of coronavirus.

In a recent bulletin, it also said that AY.3 has been identified as a new sub-lineage of Delta and it is defined by ‘ORF1a:I3731V common AY.1 mutations except for S:417’.

It is primarily seen in the US with single reclassified case in the UK and India.

There are no known significant properties of this mutation but since it is a Delta VOC sub-lineage, INSACOG will continue to monitor it, the bulletin stated.

“It is likely that neither AY.1 nor AY.2 is more transmissible than Delta. They also continue to be below 1 per cent in available sequences from June in India,” the INSACOG said.

Meanwhile, the total number of COVID-19 vaccine doses administered in India so far has surpassed 39 crore, the Union Health Ministry said on Wednesday.

According to a provisional report at 7pm, more than 32.10 lakh vaccine doses were administered on Wednesday.

Cumulatively, 11,78,70,724 people in the age group 18-44 years have received the first dose and 41,92,141 their second dose since the start of phase three of the vaccination drive.

Eight states — Uttar Pradesh, Madhya Pradesh, Rajasthan, Tamil Nadu, Bihar, Gujarat, Karnataka and Maharashtra — have administered more than 50 lakh first dose of COVID-19 vaccine in the age group of 18-44 years, the ministry said.
