Continuing Covid-19 outbreaks across India are attributable to the Delta variant, a susceptible population and reduced vaccine effectiveness in blocking transmission, the INSACOG, a genome sequencing government consortium of laboratories, has said.

However, vaccination continues to be very effective in reducing severe disease and death, and public health measures to reduce transmission and inoculation remain critical, the INSACOG stressed in its latest bulletin dated August 16. As of now sequencing of vaccination breakthroughs in India is also showing a very high proportion of Delta variant, the INSACOG said.
