New Delhi: A new study has claimed that the Delta variant of COVID-19 is eight times less sensitive to coronavirus vaccine antibodies as compared to the original strain that was first reported in China s Wuhan.
The study titled Sars-Cov-2 B.1.617.2 Delta Variant Emergence and Vaccine Breakthrough: Collaborative Study , was conducted on more than 100 healthcare workers (HCWs) at three centres across India including Sir Ganga Ram Hospital (SGRH) in Delhi. The collaborative study from India was conducted along with scientists from the Cambridge Institute of Therapeutic Immunology and Infectious Disease. It, however, is yet to be peer-reviewed.
It stated that the B.1.617.2 Delta variant, first found in India, not only dominates vaccine-breakthrough infections with higher respiratory viral loads compared to non-Delta infections but also generates greater transmission among the fully vaccinated healthcare workers.

Synopsis
The study found that the Delta variant not only dominated vaccine-breakthrough infections with higher viral loads compared with non-Delta infections (Ct value of 16.5 versus 19), but also generated greater transmission among the fully vaccinated HCWs.
Reuters This is an eye-opener to the fully vaccinated people that you cannot lower your guard in the name of vaccination. Dr Chand Wattal, chairperson, Institute of Clinical Microbiology and Immunology, SGRH, said.
(This story originally appeared in on Jul 05, 2021)The Delta variant of coronavirus is eight times less sensitive to antibodies generated by vaccines compared with the original strain that came from China’s Wuhan, revealed a new study.
A study conducted on 100 healthcare workers across three centers in India has found the Delta variant eight times less sensitive to antibodies generated by the COVID-19 vaccine, a local media report said Monday.
The study, named Sars-Cov-2 B.1.617.2 Deltavariant Emergence and Vaccine Breakthrough: Collaborative Study , also found that the variant has a much higher capacity to infect more people.
The collaborative study from India was conducted along with scientists from the Cambridge Institute of Therapeutic Immunology and Infectious Disease. The B.1.617.2 Delta variant not only dominates vaccine-breakthrough infections with higher respiratory viral loads compared to non-delta infections but also generates greater transmission between fully vaccinated healthcare workers, as compared to other variants B.1.1.7 (Alpha variant) or B.1.617.1 (Kappa variant), the findings of the study revealed.
