'You have sufficient protection if you take the second dose of the Covishield vaccine at 12 weeks, because this vaccine works in a way where it provides protection in the first dose.'
A team at Bristol University used recently developed techniques to validate that the vaccine accurately follows the genetic instructions programmed into it by the Oxford University team.
The Oxford/AstraZeneca vaccine is also being produced as part of a tie-up by the Serum Institute of India.
However, in two different dose regimens, the vaccine's efficacy was 90 per cent in one and 62 per cent in the other.
More than 2 million people have been diagnosed with coronavirus across the world, and the pharmaceutical industry is pulling out all stops to find potential treatments and vaccines for the global pandemic. According to the World Health Organization, there are now more than 70 potential vaccines under evelopment, with some already in clinical trials.
'On a daily basis you are saying, you do this, you do that, but where is the blueprint of the war?' 'How many isolations actually we need per hundred thousand people?' 'How many ventilators will we need for 100,000 people?'
