NEW DELHI: Breakthrough infections of SARS-CoV2 after vaccination against Covid-19 are common across the globe during Delta outbreaks and genome sequencing of such cases in India currently also shows high proportion of Delta variant, the Indian SARS-CoV-2 Consortium on Genomics (INSACOG) says in its latest report.
This assumes significance amid concerns about rising breakthrough infections in the country with many wondering whether there are new variants emerging and are existing vaccines going to be effective against them.
The INSACOG report underlines that vaccination continues to be very effective in reducing severe disease and death, whereas the continuing outbreaks across India are related to Delta and reduced vaccine effectiveness in blocking transmission, among other factors.
“Continuing outbreaks across India are attributable to Delta, a susceptible population, reduced vaccine effectiveness in blocking transmission, and opportunities for transmission. Vaccination continues to be very effective in reducing severe disease and death. Public health measures to reduce transmission and vaccination remain critical,” the consortium said in its report.
It also highlighted that while investigations for new variants are ongoing, concern regarding appearance of new variants should be calibrated in the context of global outbreaks of SARS-CoV2 infection after Covid vaccination.
The UK, with a population of about 6.7 crore, has reported about 18 lakh cases and 1.2 lakh vaccination breakthroughs with Delta, since April 2021, it noted.
