AstraZeneca: COVID-19 vaccine shown to be 'highly effective'

Drugmaker AstraZeneca said Monday that late-stage trials showed its COVID-19 vaccine is highly effective, buoying the prospects of a relatively cheap, easy-to-store product that may become the vaccine of choice for the developing world. The results are based on an interim analysis of trials in the U.K. and Brazil of a vaccine developed by Oxford University and manufactured by AstraZeneca. No hospitalizations or severe cases of COVID-19 were reported in those receiving the vaccine. AstraZeneca is the third major drug company to report late-stage data for a potential COVID-19 vaccine as the world waits for scientific breakthroughs that will end a pandemic that has pummeled the world economy and led to 1.4 million deaths. But unlike the others, the Oxford-AstraZeneca vaccine doesn’t have to be stored at freezer temperatures, making it potentially easier to distribute, especially in developing countries.
