@broadmind hello and welcome to KU Buckets! How’s life on the other side? This is an excellent question. This article provides some answers: https://www.statnews.com/2020/07/20/study-provides-first-glimpse-of-efficacy-of-oxford-astrazeneca-covid-19-vaccine/ Basically, the vaccine developed by Oxford with AstraZennica is in phase 3 trials (being tested on 15k people) and the Cansino vaccine developed in China is about to start phase 3 (ie large group) testing. We will have the results in October or November. Assuming success, from there I don’t know the turnaround to widespread availability in various parts of the globe.
