CNBC reports that the World Health Organization said that coronavirus vaccination rollouts using the AstraZeneca-Oxford University shot should continue while it carries out a safety review.

The latest guidance from the global public health body comes after a raft of European countries announced that they would suspend use of the shot over concerns that it could be linked to reported cases of blood clots in the region.

On Wednesday, the WHO issued a statement in which it said that “vaccination against COVID-19 will not reduce illness or deaths from other causes.”

It said that while it was routine for countries to signal potential adverse events following immunization, particularly in mass vaccination campaigns, “this does not necessarily mean that the events are linked to vaccination itself.”

Nonetheless, it added, “it is good practice to investigate them. It also shows that the surveillance system works and that effective controls are in place.”
