Oxford University and AstraZeneca became the first Covid-19 vaccine makers to publish final-stage clinical trial results in a scientific journal, clearing a key hurdle in the global race to produce safe and effective drugs for the new coronavirus.
The study, published in the respected Lancet medical journal, confirmed that the vaccine works in an average of 70 per cent of cases, according to AFP.
It comes during a flurry of positive developments that have raised hopes the roll-out of vaccines can help begin to restrain a pandemic that has killed more than 1.5 million people and stricken societies worldwide.
