MUMBAI/ PUNE: In the largest study done so far in India to understand why people got Covid-19 despite taking one or two vaccine shots, scientists from the Pune-based National Institute of Virology (NIV) found a simple answer: B.1.617.2, that is better known as the Delta variant.
The Delta variant was found in 87% of the 677 throat and nasal swabs of Covid-19 patients from 17 states and union territories. While 592 of these patients had taken two doses, 85 had taken only one dose before getting infected with the SARS2 virus.
The genomic analysis showed the Delta variant’s presence in the majority of the samples, but there also were other variants such as Alpha, Kappa, Delta AY.1 (known as the Delta-plus variant in samples from Madhya Pradesh and Rajasthan) and Delta AY.2. The study, led by director Dr Priya Abraham and senior scientist Dr Pragya Yadav, also found that less than 10% of the 677 patients needed hospitalisation, alluding to the vaccine’s effectiveness in preventing a severe infection.
Three patients who had taken both the shots died, but their age and existing medical conditions were not mentioned. Over 20% of these patients had comorbidities such as diabetes, hyptertension or chronic lung, heart or kidney conditions. “The most important point of our study is that vaccination offers more than 99% protection against death even in the presence of the Delta strain,” said Dr Yadav.
