ROME (Reuters) – There is a link between AstraZeneca’s COVID-19 vaccine and very rare blood clots in the brain but the possible causes are still unknown, a senior official for the European Medicines Agency (EMA) said in an interview published on Tuesday.
However, the EMA later said in a statement that its review of the vaccine was ongoing and it expected to announce its findings on Wednesday or Thursday. An AstraZeneca spokesman declined to comment on the matter.
