Denmark and Norway have temporarily halted use of the Oxford-AstraZeneca vaccine as a precaution against coronavirus.
The suspension came after Danish reports of some people having blood clots after vaccination and one death, the BBC reports.
This is coming three days after Austria suspended vaccination with a batch of the vaccine after a 49-year-old woman died as a result of severe coagulation disorder, and a 35-year-old woman developed a pulmonary embolism.
The EU medicines agency has emphasised there is no indication the vaccine had caused blood clots.
It said the number of cases in vaccinated people was no higher than in the general population.
Several European countries have now stopped using two batches of the drug.
AstraZeneca said the drug’s safety had been studied extensively in clinical trials.
The suspension of AstraZeneca vaccine by the European countries is coming after Nigeria began the vaccination of its citizens with the vaccine.
Nigeria took delivery of 3.92 doses of the vaccines last week Tuesday.
President Muhammadu Buhari and Vice President Yemi Osinbajo took their first jabs on Saturday.
Many state governors and top government officials in Nigeria have started taking their shots of the vaccines.
