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.

Astra and Oxford officials said they’re preparing to submit the findings to regulators and don’t expect the different outcomes in the study to affect the process. The U.S. could potentially take longer to sign off because a clinical trial in that country will need more time before it delivers results.

The larger U.S. Astra trial, which could be key for approval there, has injected about 10,500 people with both doses. Mene Pangalos, Astra’s head of biopharma research, told reporters the team is planning to talk to the U.S. Food and Drug Administration immediately and hopes to have another arm administering the half dose-full dose regimen starting within weeks.

AstraZeneca expects to have more than 300 million doses ready to ship globally by the end of the first quarter of next year, with about 100 to 200 million doses being produced monthly. For the U.K., the company expects to have up to 4 million doses ready by year-end, and 40 million by the end of the first quarter
