One jab could also offer protection of up to 76% for up to 12 weeks, a new study shows
A single dose of the Oxford/AstraZeneca vaccine may reduce transmission by 67% and give protection of 76% for up to 12 weeks, a study shows.
Vaccine efficacy from two standard doses is 82.4% with the three-month interval being used in the UK, researchers from the University of Oxford say. The data from the study, which has not yet been peer reviewed, supports the four- to 12-week prime-boost dosing interval that many global regulators have recommended.
