“Vaccine for the world” found to be 79 % effective

“Vaccine for the world” – COVID-19 Vaccine by Oxford University and AstraZeneca was found to be 79 % effective against symptomatic COVID-19 and 100 % effective against severe illness. New clinical study data was released from recent studies carried out in United States, Chile and Peru. Including 32,449 adult participants in all age groups (most from United States), the study participants received either two doses of the Oxford-AstraZeneca vaccine or a placebo between four-week time. The two-shot system was completely effective at preventing severe cases of illness in the new studies. Five cases of severe illness were found in the new studies – all of them had received a placebo.
