• AstraZeneca issues a press release from a 32,449- person, placebo-controlled, randomized phase III trial of its coronavirus vaccine which took place in the US, Chile and Peru. Overall, the two-dose vaccine, given four weeks apart, was 79 percent effective at preventing symptomatic COVID-19, and 100 percent effective at preventing severe COVID-19 and hospitalization; a longer dosing interval may boost effectiveness. There were no significant safety concerns- including cases of thrombosis –  among  21,583 participants given at least one  dose of vaccine. Source
