British scientists racing to develop the world’s first Covid-19 vaccine have accidentally given clinical trial participants the wrong dose.
The mistake will be a huge embarrassment for the Oxford Covid-19 vaccine trial viewed as being in pole position to produce the first jab.
The first of 30 million doses for Brits had been expected to be approved as soon as September. Oxford University insists “no pause to the study is required” after a smaller dose was administered.
The trial is the focus of scientists around the globe after it’s leaders took the unusual step of announcing before human trials that they were “80% confident” the vaccine candidate would work.
