(CNN) Drugmaker AstraZeneca announced on Monday that its experimental coronavirus vaccine has shown an average efficacy of 70% in large-scale trials -- the latest of several vaccine trials worldwide to post their results this month. That averages to a 70% efficacy, AstraZeneca said. He said that the results of the trials were "exciting" and demonstrated that they had an "effective vaccine that will save many lives." Trials of the AstraZeneca Oxford vaccine were carried out around the world, including in the UK, the US, Japan, Russia, South Africa, Kenya and several Latin American countries. At 70%, the AstraZeneca vaccine's average efficacy is greater than the level of efficacy that the US Food and Drug Administration aimed for, which was at least 50% efficacy.
