LONDON (March 18): The benefits of AstraZeneca's Covid-19 vaccine far outweigh any risks and countries across Europe should continue to use it to help save lives, the World Health Organization's (WHO) European director said on Thursday.

Hans Kluge noted that Europe's medicines regulators are investigating a small number of cases of blood clots in the region that have prompted around a dozen EU governments to suspend use of the AstraZeneca shot.
