COVID Vaccination Reduces Mortality Due To Delta Variant, Shows ICMR Study In Chennai
Highlights
  • 354 COVID vaccinated people including 241 partially vaccinated were studied
  • Progression of illness seems to be prevented by COVID vaccination: Study
  • Non-pharma interventions must continue to slow down the transmission: Study

Chennai: An Indian Council of Medical Research (ICMR) study conducted in Chennai has found that the Delta variant has the potential to infect both vaccinated and unvaccinated individuals, but it reduces mortality among the former group. According to a study published in the Journal of Infection on August 17 and approved by the Institutional Ethics Committee of ICMR-National Institute of Epidemiology, Chennai indicates that the prevalence of the Delta variant or B.1.617.2 was not different between the vaccinated and unvaccinated groups.

B.1.617.2 has the potential to infect both vaccinated and unvaccinated individuals. However, the progression of illness seems to be prevented by vaccination. Therefore, non-pharmaceutical interventions must continue to slow down the transmission. Additionally, the pace and scale of vaccination have to be increased to mitigate the further waves of the pandemic, the report read.

“Systematic genomic surveillance must be carried out to monitor the emergence of newer variants and assess their capacity to evade infection/vaccine-induced immunity,” it added.

The report also quoted other studies that have reported a reduction in neutralisation among Covishield and Covaxin vaccine beneficiaries after infection with the Delta variant.

India experienced a severe second wave of SARS-CoV-2 infections during the months of April and May 2021. COVID-19 vaccination with BBV152 vaccine (Covaxin; Bharat Biotech) and ChAdOx1 nCoV-19 (Covishield, Serum Institute of India) was started in the country in January 2021, targeting healthcare workers in the first phase and later expanded to include adult population groups. Breakthrough infections following vaccination have been reported in India, the report said.

“Breakthrough infections could be due to the emergence of newer mutant strains capable of escaping the host immune response,” it added.

According to the report, Chennai was one of the worst affected cities during the second wave of Covid-19 in India with nearly 6000 cases reported daily during the first three weeks of May 2021, despite a high seroprevalence of around 45 per cent estimated during October-November 2020. The study included patients from three triaging centres in Chennai. And the findings indicate that out of the 3,790 people who visited the triage centres between the first week of May, 373 reported receiving at least one dose of vaccine 14 days prior to their Covid-19 positive diagnosis. The remaining 3,417 were unvaccinated. However, according to the report, no deaths were reported in the fully vaccinated group, whereas three partially vaccinated (patients) and seven unvaccinated patients died.

The study enrolled 354 (94.9 per cent) of the 373 in the vaccinated group. Out of these 241 people had taken one dose or were partially vaccinated and 113 had taken two doses or were fully vaccinated. As many as 185 (5.4 per cent) of the 3417 unvaccinated individuals were included in the study. The median age of the individuals who were unvaccinated, partially vaccinated and fully vaccinated were 47 years, 53 years and 54 years respectively. The study, however, could not follow up around 5 per cent of the study participants.

NDTV – Dettol Banega Swasth India campaign is an extension of the five-year-old Banega Swachh India initiative helmed by Campaign Ambassador Amitabh Bachchan. It aims to spread awareness about critical health issues facing the country. In wake of the current COVID-19 pandemic, the need for WASH (WaterSanitation and Hygiene) is reaffirmed as handwashing is one of the ways to prevent Coronavirus infection and other diseases. The campaign highlights the importance of nutrition and healthcare for women and children to prevent maternal and child mortality, fight malnutrition, stunting, wasting, anaemia and disease prevention through vaccines. Importance of programmes like Public Distribution System (PDS), Mid-day Meal Scheme, POSHAN Abhiyan and the role of Aganwadis and ASHA workers are also covered. Only a Swachh or clean India where toilets are used and open defecation free (ODF) status achieved as part of the Swachh Bharat Abhiyan launched by Prime Minister Narendra Modi in 2014, can eradicate diseases like diahorrea and become a Swasth or healthy India. The campaign will continue to cover issues like air pollutionwaste managementplastic banmanual scavenging and sanitation workers and menstrual hygiene
