LONDON – The results of a large US study showed that the coronavirus vaccine developed by AstraZeneca and the University of Oxford is 79% effective in preventing symptomatic illness and 100% effective against serious illness and hospitalization.

The results were published on Monday.

It comes shortly after a spate of countries temporarily suspended the use of the shot after reports of blood clots in some vaccinated people.

Germany, France, Italy and Spain are among those who have resumed use of the Oxford-AstraZeneca vaccine after the European Medicines Agency found the shot was safe and effective during its initial investigation into possible side effects.

This is a developing story and will be updated shortly.
