As the number of coronavirus cases in the country subsides, government officials continue to encourage people to take their vaccine shots as soon as possible. While people are still sceptical and have their own reservations about vaccine efficacy, experts bel…

In the study conducted by a team of experts from the AIIMS-IGIB (Institute of Genomics and Integrative Biology), 63 symptomatic patients, who had reported persistent fever for five to seven days, were observed and evaluated. Of the 63 individuals, 36 patients had received two doses, while 27 had received one dose of vaccine. “Ten patients received AZD1222/Covishield while 53 received BBV152/Covaxin,” the study read.
About 76.9 percent of infections by the Delta variant were reported in people who had got only one dose of the vaccine, whereas 60 percent in people who had received both doses.
The NCDC-IGIB study suggested that breakthrough infections due to the Delta variant was higher in people who had received Covishield vaccine. About 27 patients who had taken Covishield reported delta’ breakthrough infections, with an infection rate of 70.3 percent.
The study commented on the rising number of COVID patients infected with the Delta variant and said, “”Reinfections and vaccine breakthrough infections are rare occurrences and genomic sequencing of vaccine breakthrough infections can provide useful insights. In the present group of vaccine breakthrough infections investigated using genome sequencing, closely overlapping and mirroring the COVID-19 cases in the states of Delhi, the variants of concern B.1.617.2 and B.1.1.7 comprised the majority, but the proportions were not significantly different in comparison with the population prevalence of the variants during this period with high community transmission.”
