Delta Variant Of Coronavirus Eight Times Less Sensitive To Vaccine Antibodies, Says Study

INDIA Team Latestly|

Delta variant of coronavirus is eight times less sensitive to antibodies generated by vaccines as compared to the original strain that came from China’s Wuhan, according to a new study. The study was conducted on more than 100 healthcare workers (HCWs) at three centres in India. Sir Ganga Ram Hospital (SGRH), a centre where the study was conducted found that the B.1.617.2 Delta variant not only dominates vaccine-breakthrough infections with higher respiratory viral loads compared to non-Delta infections (Ct value of 16.5 versus 19) but also generates greater transmission among the fully vaccinated HCWs. The collaborative study, “Sars-Cov-2 B.1.617.2 Delta Variant Emergence and Vaccine Breakthrough: Collaborative Study”, from India with scientists from Cambridge Institute of Therapeutic Immunology & Infectious Disease is yet to be peer-reviewed. It revealed that in vitro, the Delta variant is approximately eight-fold less sensitive to vaccine-elicited antibodies compared to Wuhan-1. Based on recent data and the dominance of new infections by this variant, the B.1.167.2 Delta variant appears more transmissible than B.1.1.7 in the UK, the study revealed.
