  • According to an ICMR study, the Delta variant has the ability to infect both vaccinated and unvaccinated people.
  • The study also added that vaccination also lowers the risk of death from the Delta variant of COVID-19.

According to a research conducted by the Indian Council of Medical Research (ICMR) in Chennai, the Delta strain of coronavirus has the ability to infect both vaccinated and unvaccinated persons, though it reduces mortality in the former group.

The ICMR-National Institute of Epidemiology’s Institutional Ethics Committee authorised the study, which was published on August 17 in the Journal of Infection.

The prevalence of B.1.617.2 did not differ between the vaccinated and unvaccinated groups, according to the study’s findings. The prevalent circulating strain, Delta, was a major contributor to the second wave of SARS-CoV-2 in India.

According to the findings, “B.1.617.2 has the potential to infect both the vaccinated and unvaccinated individuals.” The report added, “However, the progression of illness seems to be prevented by vaccination. Therefore, non-pharmaceutical interventions must continue to slow down the transmission.”

To reduce the prevalence of the pandemic, the speed and scale of vaccination must be boosted. It went on to say that systematic genomic surveillance is needed to track the development of novel variants and assess their ability to evade infection/vaccine-induced immunity.

Important highlights of the study:

  • Vaccine breakthrough SARS-CoV-2 infections were recorded in India during the COVID-19 second wave.
  • There was no difference in the prevalence of the Delta (B.1.617.2) mutant between the vaccinated and unvaccinated groups.
  • When compared to the unvaccinated group, the progression of COVID-19 cases to severe illness and death was reduced in the vaccinated group.

Meanwhile, INSACOG, the organization in charge of detecting COVID19 mutations, has said that the Delta variation was primarily responsible for a breakthrough in infections in fully vaccinated individuals in India.

It went on to say that the Delta strain is still the most serious Variant of Concern (VOC) in India, and that research into any new variants is underway.
