Delta Plus variant: Transmissibility & vaccine response against new mutation

Vaccines Covishield and Covaxin work against SARS-CoV-2 variants Alpha, Beta, Gamma and Delta, while effectiveness tests against the Delta Plus variant is ongoing, the government said on Friday. There are four variants of concern of the coronavirus disease -- Alpha, Beta, Gamma and Delta -- with Delta Plus being a sub-lineage of the Delta variant which is also a variant of concern. "Covishield reduces slightly with Alpha, by 2.5 times. For the Delta variant, Covaxin is effective but antibody response is slightly reduced to three-fold reduction, and for Covishield, it is two-fold reduction, while in Pfizer and Moderna it is seven-fold reduction," he said.
