LONDON – Developed by UK pharmaceutical company AstraZeneca in partnership with Oxford University, the coronavirus vaccine is the first whose late-stage study results have been independently reviewed and published in a medical journal.

The interim results from the Phase 3 studies with the Oxford-AstraZeneca vaccine were published in the Lancet on Tuesday. Peer review means that articles or studies are reviewed by other experts in the field before they are published and serve as an additional quality control measure on the results.

The study replicated the vaccine study results published a few weeks ago, which showed an average of 70% effectiveness in protecting against the coronavirus.

The two dosage regimens used were also repeated, with the two full doses exhibiting 62% effectiveness and 90% effectiveness demonstrated with the half-then-full dosage regimen.
