Countries should not stop using AstraZeneca’s coronavirus (COVID-19) vaccine over fears it causes blood clots as there is no indication this is true, the World Health Organisation (WHO) says.
Bulgaria is the latest country to suspend use of the vaccine.
But a WHO spokeswoman told a briefing on Friday there was no link between the jab and developing a clot.
‘Excellent vaccine’
Margaret Harris said it was an “excellent vaccine” and should continue to be used.
Around five million Europeans have already received the AstraZeneca jab.
There have been about 30 cases in Europe of “thromboembolic events” – or developing blood clots – after the vaccine was administered. There were also reports that a 50-year-old man had died in Italy after developing deep vein thrombosis (DVT).
The WHO is investigating the reports, as it does any safety questions, Harris said.
No causal relationship
But no causal relationship had been established between the shot and the health problems reported, she said.
Bulgaria’s decision to pause its rollout follows similar steps by Denmark, Iceland and Norway as well as Thailand. Italy and Austria have stopped using certain batches of the drug as a precautionary measure.
“I order a halt in vaccinations with the AstraZeneca vaccine until the European Medicines Agency dismisses all doubts about its safety,” Bulgarian Prime Minister Boyko Borisov said.
The European Medicines Agency, the EU’s medicines regulator, said earlier there was no indication the jab was causing the blood clots, adding that its “benefits continue to outweigh its risks”.
AstraZeneca said the drug’s safety had been studied extensively in clinical trials.
Other countries, including the UK, Germany, Australia and Mexico, have said they are continuing their rollout. (BBC)
