SARS-CoV-2 Delta variant's effect on COVID-19 vaccine efficacy

In a recent research paper published in the journal Infection, the scientists estimated the transmission and disease severity associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant and the effectiveness of the current coronavirus disease 2019 (COVID-19) vaccines against the same by conducting a literature review. Further, a meta-analysis was conducted to obtain a numeric estimate of the vaccine effectiveness against the Delta variant.
