It is the second occasion that Dutch health authorities halt AstraZeneca vaccine use after a two-week suspension approved last month.
Recently, the European Medicines Agency authorized a new name (Vaxzevria) after AstraZeneca applied for the change. The agency maintains that the vaccine is "effective and safe" but does not rule out isolated risks.
"The key question is whether the problems observed in these people are due to conditions before, or after, the vaccine. Until then, it is best to press the caution button," De Jonge stressed.
