A Covid-19 vaccine developed by the University of Oxford and AstraZeneca Plc prevented a majority of people from getting the disease in a large trial, another promising development in the quest to end the pandemic, and the rollout could begin next month.

The vaccine stopped an average of 70% of participants from falling ill, an early analysis of the data show. The effectiveness rose to 90% for one of two regimens, using half a dose followed by a full one later, close to the high bar set by Pfizer Inc. and Moderna Inc.
