The Netherlands has become the latest country to suspend use of the Oxford-AstraZeneca coronavirus vaccine over concerns about possible side effects.
The Dutch government said the move, which will last until at least 29 March, was a precaution.
The Republic of Ireland earlier made a similar decision over reports of blood clotting in recipients in Norway.
But the World Health Organization says there is no indication of a link between the vaccine and blood clots.
The announcements by the Netherlands and Ireland followed similar moves by Denmark, Norway, Bulgaria, Iceland and Thailand.
The European Medicines Agency (EMA) – which is currently carrying out a review into incidents of blood clots – says the vaccine’s benefits continue to outweigh its risks.
