Oxford-AstraZeneca Covid vaccine shows 70% efficacy: All you need to know
The coronavirus vaccine developed by Oxford University & AstraZeneca has showed 70% efficacy against the disease in the trials. One dosing regimen showed vaccine efficacy of 90% when it was given as a half dose, followed by a full dose at least one month apart. AstraZeneca said that no serious safety events related to the vaccine have been confirmed and added that the vaccine was well tolerated across both dosing regimens. AstraZeneca is now preparing regulatory submissions of the data to authorities around the world that have a framework in place for conditional or early approval. The announcement was several people including UK Prime Minister Boris Johnson and Health Secretary Matt Hancock. Adar Poonawalla, the CEO of Serum Institute of India which is producing Oxford-Astrazeneca vaccine, apart from conducting trials in India, also expressed happiness at the announcement. Compared to Moderna and Pfizer which have claimed around 94% efficacy, Oxford's initial reports appear to be less promising. However, the Pfizer vaccine needs minus 70 degree Celcius temperature for storage. Watch the full video for all the details.
