British health authorities have so far identified 30 cases of blood clots developing after someone was vaccinated with the corona vaccine from pharmaceutical AstraZeneca.

That is 25 more than was reported last month.

In 22 cases, a vaccinated person experienced blood clots (thrombosis). The remaining 8 cases had a platelet deficiency. According to the agency, there are no known cases of people getting blood clots after being vaccinated with the Pfizer / BioNTech vaccine.

The UK Office for the Regulation of Medicines and Health Products reported on March 18 that 5 cases were known in the UK, while 11 million Britons had been injected with the vaccine at the time. Some 18.1 million injections are said to have been taken with the AstraZeneca vaccine.

The European Medicines Agency (EMA) still sees no evidence of a link between rare blood problems and AstraZeneca’s corona vaccine. The European regulator’s safety committee spoke on Wednesday about reports of thrombosis and platelet deficiency in a tiny proportion of people who have received the injection. So far, the experts do not see a causal relationship, but they believe it is possible.

British health authorities said on Thursday they still believe the benefits of the vaccine outweigh the potential risk of blood clots.

However, some countries restrict the use of the AstraZeneca vaccine because of the potential risk. As a precaution, the German government has decided to only give the vaccine to people aged 60 and older.

EMA expects to come up with new conclusions and recommendations at the end of next week, between 6 and 9 April. The findings of the safety committee are leading for the Dutch government and health authorities.
