LONDON – The Delta variant of SARS-CoV-2 originally identified in India is causing more serious illness and reducing the effectiveness of vaccines compared to the Alpha (Kent) variant, according to a nationwide study covering Scotland’s whole population of 5.4 million.
New phase III data on Celltrion Inc.'s COVID-19 therapy, regdanvimab, showed it reduced the risk of hospitalization or death related to the disease for high-risk patients to 3.1% vs. 11.1% for placebo by day 28 of the study. The treatment also proved beneficial to participants across all risk categories, reducing their risk of hospitalization or death to 2.4% vs. 8% for placebo at the same time point.
