The National Centre for Disease Control (NCDC) and All India Institute of Medical Science (AIIMS) in collaboration with the Institute of Genomics and Integrative Biology (IGIB) have done two separate studies which have shown that the Delta variant of COVID-19 can infect people who have received one or two jabs of either Covishield or Covaxin. In the AIIMS-IGIB study no death has been reported in the 63 subjects, but the study has found out that the Delta variant is predominant in the reinfection cases.
The study concluded, “Reinfections and vaccine breakthrough infections are rare occurrences and genome sequencing can provide useful insights. In the present group of vaccine breakthrough infections investigated closely overlapping the COVID cases in Delhi, the Delta variants compromised the majority, but the proportions were not significantly different compared to the population prevalence of the variants during this period with high community transmission”.
While on Monday, an ICMR study claims that Bharat Biotech’s Covaxin is effective in neutralizing both COVID variants -B.1.351 (Beta) and B.1.617.2 (Delta). The study, yet to be peer-reviewed.
