Oxford COVID-19 vaccine up to 90% effective (with the right dose)

A third major coronavirus vaccine candidate has revealed promising results in late-stage trials, as researchers announced the so-called Oxford vaccine is around 70% effective in preventing COVID-19; and it can be 90% effective when given at a specific dose, according to a statement released on Monday (Nov. 23).

The news follows recent announcements from Pfizer and Moderna that their coronavirus vaccines were both around 95% effective. Though showing a relatively lower (but still promising) efficacy, the Oxford vaccine is cheaper and easier to distribute than the other two.
