Preprint: Prevalent evidence of coronavirus variant B.1.617.2 Delta in post-vaccinated individuals in India
“We sequenced all samples of vaccination-breakthrough cases at NCDC, Delhi, over the period of the study. Two VOC lineages were seen amongst 27 cases: B.1.617.1 (n=2; 8%), B.1.617.2 (n=19; 76%). Other samples had the background B.1 lineages (16%).
It is noted that when compared to population prevalence, B.1.617.2 was over-represented and B.1.1.7 was not even detected in vaccination breakthroughs, suggesting higher breakthrough risk of B.1.617.2 compared to B.1.1.7.”
